### <a id="225"></a> ClickHouse release 22.5, 2022-05-19
#### Upgrade Notes
* Now, background merges, mutations and `OPTIMIZE` will not increment `SelectedRows` and `SelectedBytes` metrics. They (still) will increment `MergedRows` and `MergedUncompressedBytes` as it was before. This only affects the metric values, and makes them better. This change does not introduce any incompatibility, but you may wonder about the changes of metrics, so we put in this category. [#37040](https://github.com/ClickHouse/ClickHouse/pull/37040) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
* Updated the BoringSSL module to the official FIPS compliant version. This makes ClickHouse FIPS compliant. [#35914](https://github.com/ClickHouse/ClickHouse/pull/35914) ([Meena-Renganathan](https://github.com/Meena-Renganathan)). The ciphers `aes-192-cfb128` and `aes-256-cfb128` were removed, because they are not included in the FIPS certified version of BoringSSL.
* `max_memory_usage` setting is removed from the default user profile in `users.xml`. This enables flexible memory limits for queries instead of the old rigid limit of 10 GB.
* Disable `log_query_threads` setting by default. It controls the logging of statistics about every thread participating in query execution. After supporting asynchronous reads, the total number of distinct thread ids became too large, and logging into the `query_thread_log` has become too heavy. [#37077](https://github.com/ClickHouse/ClickHouse/pull/37077) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Remove function `groupArraySorted` which has a bug. [#36822](https://github.com/ClickHouse/ClickHouse/pull/36822) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
#### New Feature
* Enable memory overcommit by default. [#35921](https://github.com/ClickHouse/ClickHouse/pull/35921) ([Dmitry Novik](https://github.com/novikd)).
* Add support of GROUPING SETS in GROUP BY clause. This implementation supports a parallel processing of grouping sets. [#33631](https://github.com/ClickHouse/ClickHouse/pull/33631) ([Dmitry Novik](https://github.com/novikd)).
* Added `system.certificates` table. [#37142](https://github.com/ClickHouse/ClickHouse/pull/37142) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
* Adds `h3Line`, `h3Distance` and `h3HexRing` functions. [#37030](https://github.com/ClickHouse/ClickHouse/pull/37030) ([Bharat Nallan](https://github.com/bharatnc)).
* New single binary based diagnostics tool (clickhouse-diagnostics). [#36705](https://github.com/ClickHouse/ClickHouse/pull/36705) ([Dale McDiarmid](https://github.com/gingerwizard)).
* Add output format `Prometheus` [#36051](https://github.com/ClickHouse/ClickHouse/issues/36051). [#36206](https://github.com/ClickHouse/ClickHouse/pull/36206) ([Vladimir C](https://github.com/vdimir)).
* Add `MySQLDump` input format. It reads all data from INSERT queries belonging to one table in dump. If there are more than one table, by default it reads data from the first one. [#36667](https://github.com/ClickHouse/ClickHouse/pull/36667) ([Kruglov Pavel](https://github.com/Avogar)).
* Show the `total_rows` and `total_bytes` fields in `system.tables` for temporary tables. [#36401](https://github.com/ClickHouse/ClickHouse/issues/36401). [#36439](https://github.com/ClickHouse/ClickHouse/pull/36439) ([xiedeyantu](https://github.com/xiedeyantu)).
* Allow to override `parts_to_delay_insert` and `parts_to_throw_insert` with query-level settings. If they are defined, they will override table-level settings. [#36371](https://github.com/ClickHouse/ClickHouse/pull/36371) ([Memo](https://github.com/Joeywzr)).
#### Experimental Feature
* Implemented L1, L2, Linf, Cosine distance functions for arrays and L1, L2, Linf norm functions for arrays.
[#37033](https://github.com/ClickHouse/ClickHouse/pull/37033) ([qieqieplus](https://github.com/qieqieplus)). Caveat: the functions will be renamed.
* Improve the `WATCH` query in WindowView: 1. Reduce the latency of providing query results by calling the `fire_condition` signal. 2. Makes the cancel query operation(ctrl-c) faster, by checking `isCancelled()` more frequently. [#37226](https://github.com/ClickHouse/ClickHouse/pull/37226) ([vxider](https://github.com/Vxider)).
* Introspection for remove filesystem cache. [#36802](https://github.com/ClickHouse/ClickHouse/pull/36802) ([Han Shukai](https://github.com/KinderRiven)).
* Added new hash function `wyHash64` for SQL. [#36467](https://github.com/ClickHouse/ClickHouse/pull/36467) ([olevino](https://github.com/olevino)).
* Improvement for replicated databases: Added `SYSTEM SYNC DATABASE REPLICA` query which allows to sync tables metadata inside Replicated database, because currently synchronisation is asynchronous. [#35944](https://github.com/ClickHouse/ClickHouse/pull/35944) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Improvement for remote filesystem cache: Better read from cache. [#37054](https://github.com/ClickHouse/ClickHouse/pull/37054) ([Kseniia Sumarokova](https://github.com/kssenii)). Improve `SYSTEM DROP FILESYSTEM CACHE` query: `<path>` option and `FORCE` option. [#36639](https://github.com/ClickHouse/ClickHouse/pull/36639) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Improvement for semistructured data: Allow to cast columns of type `Object(...)` to `Object(Nullable(...))`. [#36564](https://github.com/ClickHouse/ClickHouse/pull/36564) ([awakeljw](https://github.com/awakeljw)).
* Improvement for parallel replicas: We create a local interpreter if we want to execute query on localhost replica. But for when executing query on multiple replicas we rely on the fact that a connection exists so replicas can talk to coordinator. It is now improved and localhost replica can talk to coordinator directly in the same process. [#36281](https://github.com/ClickHouse/ClickHouse/pull/36281) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
#### Performance Improvement
* Improve performance of `avg`, `sum` aggregate functions if used without GROUP BY expression. [#37257](https://github.com/ClickHouse/ClickHouse/pull/37257) ([Maksim Kita](https://github.com/kitaisreal)).

[#37289](https://github.com/ClickHouse/ClickHouse/pull/37289) ([Maksim Kita](https://github.com/kitaisreal)).
* Improve performance of ORDER BY, MergeJoin, insertion into MergeTree using JIT compilation of sort columns comparator. [#34469](https://github.com/ClickHouse/ClickHouse/pull/34469) ([Maksim Kita](https://github.com/kitaisreal)).
* Change structure of `system.asynchronous_metric_log`. It will take about 10 times less space. This closes [#36357](https://github.com/ClickHouse/ClickHouse/issues/36357). The field `event_time_microseconds` was removed, because it is useless. [#36360](https://github.com/ClickHouse/ClickHouse/pull/36360) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Load marks for only necessary columns when reading wide parts. [#36879](https://github.com/ClickHouse/ClickHouse/pull/36879) ([Anton Kozlov](https://github.com/tonickkozlov)).
* Improves performance of file descriptor cache by narrowing mutex scopes. [#36682](https://github.com/ClickHouse/ClickHouse/pull/36682) ([Anton Kozlov](https://github.com/tonickkozlov)).
* Improve performance of reading from storage `File` and table functions `file` in case when path has globs and matched directory contains large number of files. [#36647](https://github.com/ClickHouse/ClickHouse/pull/36647) ([Anton Popov](https://github.com/CurtizJ)).
* Apply parallel parsing for input format `HiveText`, which can speed up HiveText parsing by 2x when reading local file. [#36650](https://github.com/ClickHouse/ClickHouse/pull/36650) ([李扬](https://github.com/taiyang-li)).
* The default `HashJoin` is not thread safe for inserting right table's rows and run it in a single thread. When the right table is large, the join process is too slow with low cpu utilization. [#36415](https://github.com/ClickHouse/ClickHouse/pull/36415) ([lgbo](https://github.com/lgbo-ustc)).
* Allow to rewrite `select countDistinct(a) from t` to `select count(1) from (select a from t groupBy a)`. [#35993](https://github.com/ClickHouse/ClickHouse/pull/35993) ([zhanglistar](https://github.com/zhanglistar)).
* Transform OR LIKE chain to multiMatchAny. Will enable once we have more confidence it works. [#34932](https://github.com/ClickHouse/ClickHouse/pull/34932) ([Daniel Kutenin](https://github.com/danlark1)).
* Improve performance of some functions with inlining. [#34544](https://github.com/ClickHouse/ClickHouse/pull/34544) ([Daniel Kutenin](https://github.com/danlark1)).
* Add a branch to avoid unnecessary memcpy in readBig. It improves performance somewhat. [#36095](https://github.com/ClickHouse/ClickHouse/pull/36095) ([jasperzhu](https://github.com/jinjunzh)).
* Implement partial GROUP BY key for optimize_aggregation_in_order. [#35111](https://github.com/ClickHouse/ClickHouse/pull/35111) ([Azat Khuzhin](https://github.com/azat)).
#### Improvement
* Show names of erroneous files in case of parsing errors while executing table functions `file`, `s3` and `url`. [#36314](https://github.com/ClickHouse/ClickHouse/pull/36314) ([Anton Popov](https://github.com/CurtizJ)).
* Allowed to increase the number of threads for executing background operations (merges, mutations, moves and fetches) at runtime if they are specified at top level config. [#36425](https://github.com/ClickHouse/ClickHouse/pull/36425) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Now date time conversion functions that generates time before 1970-01-01 00:00:00 with partial hours/minutes timezones will be saturated to zero instead of overflow. This is the continuation of https://github.com/ClickHouse/ClickHouse/pull/29953 which addresses https://github.com/ClickHouse/ClickHouse/pull/29953#discussion_r800550280 . Mark as improvement because it's implementation defined behavior (and very rare case) and we are allowed to break it. [#36656](https://github.com/ClickHouse/ClickHouse/pull/36656) ([Amos Bird](https://github.com/amosbird)).
* Add a warning if someone running clickhouse-server with log level "test". The log level "test" was added recently and cannot be used in production due to inevitable, unavoidable, fatal and life-threatening performance degradation. [#36824](https://github.com/ClickHouse/ClickHouse/pull/36824) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Parse collations in CREATE TABLE, throw exception or ignore. closes [#35892](https://github.com/ClickHouse/ClickHouse/issues/35892). [#36271](https://github.com/ClickHouse/ClickHouse/pull/36271) ([yuuch](https://github.com/yuuch)).
* Option `compatibility_ignore_auto_increment_in_create_table` allows ignoring `AUTO_INCREMENT` keyword in a column declaration to simplify migration from MySQL. [#37178](https://github.com/ClickHouse/ClickHouse/pull/37178) ([Igor Nikonov](https://github.com/devcrafter)).
* Add aliases `JSONLines` and `NDJSON` for `JSONEachRow`. Closes [#36303](https://github.com/ClickHouse/ClickHouse/issues/36303). [#36327](https://github.com/ClickHouse/ClickHouse/pull/36327) ([flynn](https://github.com/ucasfl)).
* Limit the max partitions could be queried for each hive table. Avoid resource overruns. [#37281](https://github.com/ClickHouse/ClickHouse/pull/37281) ([lgbo](https://github.com/lgbo-ustc)).
* Added implicit cast for `h3kRing` function second argument to improve usability. Closes [#35432](https://github.com/ClickHouse/ClickHouse/issues/35432). [#37189](https://github.com/ClickHouse/ClickHouse/pull/37189) ([Maksim Kita](https://github.com/kitaisreal)).
* Fix progress indication for `INSERT SELECT` in `clickhouse-local` for any query and for file progress in client, more correct file progress. [#37075](https://github.com/ClickHouse/ClickHouse/pull/37075) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Fix bug which can lead to forgotten outdated parts in MergeTree table engines family in case of filesystem failures during parts removal. Before fix they will be removed only after first server restart. [#37014](https://github.com/ClickHouse/ClickHouse/pull/37014) ([alesapin](https://github.com/alesapin)).
* Implemented a new mode of handling row policies which can be enabled in the main configuration which enables users without permissive row policies to read rows. [#36997](https://github.com/ClickHouse/ClickHouse/pull/36997) ([Vitaly Baranov](https://github.com/vitlibar)).
* Play UI: Nullable numbers will be aligned to the right in table cells. This closes [#36982](https://github.com/ClickHouse/ClickHouse/issues/36982). [#36988](https://github.com/ClickHouse/ClickHouse/pull/36988) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Play UI: If there is one row in result and more than a few columns, display the result vertically. Continuation of [#36811](https://github.com/ClickHouse/ClickHouse/issues/36811). [#36842](https://github.com/ClickHouse/ClickHouse/pull/36842) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Cleanup CSS in Play UI. The pixels are more evenly placed. Better usability for long content in table cells. [#36569](https://github.com/ClickHouse/ClickHouse/pull/36569) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Finalize write buffers in case of exception to avoid doing it in destructors. Hope it fixes: [#36907](https://github.com/ClickHouse/ClickHouse/issues/36907). [#36979](https://github.com/ClickHouse/ClickHouse/pull/36979) ([Kruglov Pavel](https://github.com/Avogar)).
* After [#36425](https://github.com/ClickHouse/ClickHouse/issues/36425) settings like `background_fetches_pool_size` became obsolete and can appear in top level config, but clickhouse throws and exception like `Error updating configuration from '/etc/clickhouse-server/config.xml' config.: Code: 137. DB::Exception: A setting 'background_fetches_pool_size' appeared at top level in config /etc/clickhouse-server/config.xml.` This is fixed. [#36917](https://github.com/ClickHouse/ClickHouse/pull/36917) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Add extra diagnostic info (if applicable) when sending exception to other server. [#36872](https://github.com/ClickHouse/ClickHouse/pull/36872) ([tavplubix](https://github.com/tavplubix)).
* Allow to execute hash functions with arguments of type `Array(Tuple(..))`. [#36812](https://github.com/ClickHouse/ClickHouse/pull/36812) ([Anton Popov](https://github.com/CurtizJ)).
* Added `user_defined_path` config setting. [#36753](https://github.com/ClickHouse/ClickHouse/pull/36753) ([Maksim Kita](https://github.com/kitaisreal)).
* Allow cluster macro in `s3Cluster` table function. [#36726](https://github.com/ClickHouse/ClickHouse/pull/36726) ([Vadim Volodin](https://github.com/PolyProgrammist)).
* Properly cancel INSERT queries in `clickhouse-client`/`clickhouse-local`. [#36710](https://github.com/ClickHouse/ClickHouse/pull/36710) ([Azat Khuzhin](https://github.com/azat)).
* Allow to cancel a query while still keeping a decent query id in `MySQLHandler`. [#36699](https://github.com/ClickHouse/ClickHouse/pull/36699) ([Amos Bird](https://github.com/amosbird)).

* Now clickhouse-benchmark can read authentication info from environment variables. [#36497](https://github.com/ClickHouse/ClickHouse/pull/36497) ([Anton Kozlov](https://github.com/tonickkozlov)).
* `clickhouse-keeper` improvement: add support for force recovery which allows you to reconfigure cluster without quorum. [#36258](https://github.com/ClickHouse/ClickHouse/pull/36258) ([Antonio Andelic](https://github.com/antonio2368)).
* Improve schema inference for JSON objects. [#36207](https://github.com/ClickHouse/ClickHouse/pull/36207) ([Kruglov Pavel](https://github.com/Avogar)).
* Refactor code around schema inference with globs. Try next file from glob only if it makes sense (previously we tried next file in case of any error). Also it fixes [#36317](https://github.com/ClickHouse/ClickHouse/issues/36317). [#36205](https://github.com/ClickHouse/ClickHouse/pull/36205) ([Kruglov Pavel](https://github.com/Avogar)).
* Add a separate `CLUSTER` grant (and `access_control_improvements.on_cluster_queries_require_cluster_grant` configuration directive, for backward compatibility, default to `false`). [#35767](https://github.com/ClickHouse/ClickHouse/pull/35767) ([Azat Khuzhin](https://github.com/azat)).
* If the required amount of memory is available before the selected query stopped, all waiting queries continue execution. Now we don't stop any query if memory is freed before the moment when the selected query knows about the cancellation. [#35637](https://github.com/ClickHouse/ClickHouse/pull/35637) ([Dmitry Novik](https://github.com/novikd)).
* Nullables detection in protobuf. In proto3, default values are not sent on the wire. This makes it non-trivial to distinguish between null and default values for Nullable columns. A standard way to deal with this problem is to use Google wrappers to nest the target value within an inner message (see https://github.com/protocolbuffers/protobuf/blob/master/src/google/protobuf/wrappers.proto). In this case, a missing field is interpreted as null value, a field with missing value if interpreted as default value, and a field with regular value is interpreted as regular value. However, ClickHouse interprets Google wrappers as nested columns. We propose to introduce special behaviour to detect Google wrappers and interpret them like in the description above. For example, to serialize values for a Nullable column `test`, we would use `google.protobuf.StringValue test` in our .proto schema. Note that these types are so called "well-known types" in Protobuf, implemented in the library itself. [#35149](https://github.com/ClickHouse/ClickHouse/pull/35149) ([Jakub Kuklis](https://github.com/jkuklis)).
* Added support for specifying `content_type` in predefined and static HTTP handler config. [#34916](https://github.com/ClickHouse/ClickHouse/pull/34916) ([Roman Nikonov](https://github.com/nic11)).
* Warn properly if use clickhouse-client --file without preceeding --external. Close [#34747](https://github.com/ClickHouse/ClickHouse/issues/34747). [#34765](https://github.com/ClickHouse/ClickHouse/pull/34765) ([李扬](https://github.com/taiyang-li)).
* Improve MySQL database engine to compatible with binary(0) dataType. [#37232](https://github.com/ClickHouse/ClickHouse/pull/37232) ([zzsmdfj](https://github.com/zzsmdfj)).
* Improve JSON report of clickhouse-benchmark. [#36473](https://github.com/ClickHouse/ClickHouse/pull/36473) ([Tian Xinhui](https://github.com/xinhuitian)).
* Server might refuse to start if it cannot resolve hostname of external ClickHouse dictionary. It's fixed. Fixes [#36451](https://github.com/ClickHouse/ClickHouse/issues/36451). [#36463](https://github.com/ClickHouse/ClickHouse/pull/36463) ([tavplubix](https://github.com/tavplubix)).

* Fix timeouts in Hedged requests. Connection hang right after sending remote query could lead to eternal waiting. [#36749](https://github.com/ClickHouse/ClickHouse/pull/36749) ([Kruglov Pavel](https://github.com/Avogar)).
* Experimental feature: Fix a bug of `groupBitmapAndState`/`groupBitmapOrState`/`groupBitmapXorState` on distributed table. [#36739](https://github.com/ClickHouse/ClickHouse/pull/36739) ([Zhang Yifan](https://github.com/zhangyifan27)).
* Experimental feature: During the [test](https://s3.amazonaws.com/clickhouse-test-reports/36376/1cb1c7275cb53769ab826772db9b71361bb3e413/stress_test__thread__actions_/clickhouse-server.clean.log) in [PR](https://github.com/ClickHouse/ClickHouse/pull/36376), I found that the one cache class was initialized twice, it throws a exception. Although the cause of this problem is not clear, there should be code logic of repeatedly loading disk in ClickHouse, so we need to make special judgment for this situation. [#36737](https://github.com/ClickHouse/ClickHouse/pull/36737) ([Han Shukai](https://github.com/KinderRiven)).
* Fix vertical merges in wide parts. Previously an exception `There is no column` can be thrown during merge. [#36707](https://github.com/ClickHouse/ClickHouse/pull/36707) ([Anton Popov](https://github.com/CurtizJ)).
* Fix server reload on port change (do not wait for current connections from query context). [#36700](https://github.com/ClickHouse/ClickHouse/pull/36700) ([Azat Khuzhin](https://github.com/azat)).
* Experimental feature: In the previous [PR](https://github.com/ClickHouse/ClickHouse/pull/36376), I found that testing (stateless tests, flaky check (address, actions)) is timeout. Moreover, testing locally can also trigger unstable system deadlocks. This problem still exists when using the latest source code of master. [#36697](https://github.com/ClickHouse/ClickHouse/pull/36697) ([Han Shukai](https://github.com/KinderRiven)).
* Experimental feature: Fix server restart if cache configuration changed. [#36685](https://github.com/ClickHouse/ClickHouse/pull/36685) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Fix possible heap-use-after-free in schema inference. Closes [#36661](https://github.com/ClickHouse/ClickHouse/issues/36661). [#36679](https://github.com/ClickHouse/ClickHouse/pull/36679) ([Kruglov Pavel](https://github.com/Avogar)).
* Fixed parsing of query settings in `CREATE` query when engine is not specified. Fixes https://github.com/ClickHouse/ClickHouse/pull/34187#issuecomment-1103812419. [#36642](https://github.com/ClickHouse/ClickHouse/pull/36642) ([tavplubix](https://github.com/tavplubix)).
* Experimental feature: Fix merges of wide parts with type `Object`. [#36637](https://github.com/ClickHouse/ClickHouse/pull/36637) ([Anton Popov](https://github.com/CurtizJ)).
* Fix format crash when default expression follow EPHEMERAL not literal. Closes [#36618](https://github.com/ClickHouse/ClickHouse/issues/36618). [#36633](https://github.com/ClickHouse/ClickHouse/pull/36633) ([flynn](https://github.com/ucasfl)).
* Fix `Missing column` exception which could happen while using `INTERPOLATE` with `ENGINE = MergeTree` table. [#36549](https://github.com/ClickHouse/ClickHouse/pull/36549) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
* Fix potential error with literals in `WHERE` for join queries. Close [#36279](https://github.com/ClickHouse/ClickHouse/issues/36279). [#36542](https://github.com/ClickHouse/ClickHouse/pull/36542) ([Vladimir C](https://github.com/vdimir)).
* Fix offset update ReadBufferFromEncryptedFile, which could cause undefined behaviour. [#36493](https://github.com/ClickHouse/ClickHouse/pull/36493) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Fix hostname sanity checks for Keeper cluster configuration. Add `keeper_server.host_checks_enabled` config to enable/disable those checks. [#36492](https://github.com/ClickHouse/ClickHouse/pull/36492) ([Antonio Andelic](https://github.com/antonio2368)).
* Fix usage of executable user defined functions in GROUP BY. Before executable user defined functions cannot be used as expressions in GROUP BY. Closes [#36448](https://github.com/ClickHouse/ClickHouse/issues/36448). [#36486](https://github.com/ClickHouse/ClickHouse/pull/36486) ([Maksim Kita](https://github.com/kitaisreal)).
* Fix possible exception with unknown packet from server in client. [#36481](https://github.com/ClickHouse/ClickHouse/pull/36481) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Experimental feature (please never use `system.session_log`, it is going to be removed): Add missing enum values in system.session_log table. Closes [#36474](https://github.com/ClickHouse/ClickHouse/issues/36474). [#36480](https://github.com/ClickHouse/ClickHouse/pull/36480) ([Memo](https://github.com/Joeywzr)).
* Fix bug in s3Cluster schema inference that let to the fact that not all data was read in the select from s3Cluster. The bug appeared in https://github.com/ClickHouse/ClickHouse/pull/35544. [#36434](https://github.com/ClickHouse/ClickHouse/pull/36434) ([Kruglov Pavel](https://github.com/Avogar)).
* Fix nullptr dereference in JOIN and COLUMNS matcher. This fixes [#36416](https://github.com/ClickHouse/ClickHouse/issues/36416). This is for https://github.com/ClickHouse/ClickHouse/pull/36417. [#36430](https://github.com/ClickHouse/ClickHouse/pull/36430) ([Amos Bird](https://github.com/amosbird)).
* Fix dictionary reload for `ClickHouseDictionarySource` if it contains scalar subqueries. [#36390](https://github.com/ClickHouse/ClickHouse/pull/36390) ([lthaooo](https://github.com/lthaooo)).
* Fix assertion in JOIN, close [#36199](https://github.com/ClickHouse/ClickHouse/issues/36199). [#36201](https://github.com/ClickHouse/ClickHouse/pull/36201) ([Vladimir C](https://github.com/vdimir)).
* Queries with aliases inside special operators returned parsing error (was broken in 22.1). Example: `SELECT substring('test' AS t, 1, 1)`. [#36167](https://github.com/ClickHouse/ClickHouse/pull/36167) ([Maksim Kita](https://github.com/kitaisreal)).
* Experimental feature: Fix insertion of complex JSONs with nested arrays to columns of type `Object`. [#36077](https://github.com/ClickHouse/ClickHouse/pull/36077) ([Anton Popov](https://github.com/CurtizJ)).
* Fix ALTER DROP COLUMN of nested column with compact parts (i.e. `ALTER TABLE x DROP COLUMN n`, when there is column `n.d`). [#35797](https://github.com/ClickHouse/ClickHouse/pull/35797) ([Azat Khuzhin](https://github.com/azat)).
* Fix substring function range error length when `offset` and `length` is negative constant and `s` is not constant. [#33861](https://github.com/ClickHouse/ClickHouse/pull/33861) ([RogerYK](https://github.com/RogerYK)).

### ClickHouse release v22.5.1.2079-stable FIXME as compared to v22.4.1.2305-prestable
#### Backward Incompatible Change
* Updated the BoringSSL module to the official FIPS compliant version. This makes ClickHouse FIPS compliant. [#35914](https://github.com/ClickHouse/ClickHouse/pull/35914) ([Meena-Renganathan](https://github.com/Meena-Renganathan)).
* Now, background merges, mutations and `OPTIMIZE` will not increment `SelectedRows` and `SelectedBytes` metrics. They (still) will increment `MergedRows` and `MergedUncompressedBytes` as it was before. [#37040](https://github.com/ClickHouse/ClickHouse/pull/37040) ([Nikolai Kochetov](https://github.com/KochetovNicolai)).
#### New Feature
* add implementation of MeiliSearch storage and table function. [#33332](https://github.com/ClickHouse/ClickHouse/pull/33332) ([Mikhail Artemenko](https://github.com/Michicosun)).
* Add support of GROUPING SETS in GROUP BY clause. Follow up after [#33186](https://github.com/ClickHouse/ClickHouse/issues/33186). This implementation supports a parallel processing of grouping sets. [#33631](https://github.com/ClickHouse/ClickHouse/pull/33631) ([Dmitry Novik](https://github.com/novikd)).
* According to the design mentioned at ：[#19627](https://github.com/ClickHouse/ClickHouse/issues/19627)#issuecomment-1068772646. [#35318](https://github.com/ClickHouse/ClickHouse/pull/35318) ([徐炘](https://github.com/weeds085490)).
* Added `SYSTEM SYNC DATABASE REPLICA` query which allows to sync tables metadata inside Replicated database, because currently synchronisation is asynchronous. [#35944](https://github.com/ClickHouse/ClickHouse/pull/35944) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* - Add output format Prometheus, [#36051](https://github.com/ClickHouse/ClickHouse/issues/36051). [#36206](https://github.com/ClickHouse/ClickHouse/pull/36206) ([Vladimir C](https://github.com/vdimir)).
* Parse collations in CREATE TABLE, throw exception or ignore. closes [#35892](https://github.com/ClickHouse/ClickHouse/issues/35892). [#36271](https://github.com/ClickHouse/ClickHouse/pull/36271) ([yuuch](https://github.com/yuuch)).
* Add aliases JSONLines and NDJSON for JSONEachRow. Closes [#36303](https://github.com/ClickHouse/ClickHouse/issues/36303). [#36327](https://github.com/ClickHouse/ClickHouse/pull/36327) ([flynn](https://github.com/ucasfl)).
* Set parts_to_delay_insert and parts_to_throw_insert as query-level settings. If they are defined, they can override table-level settings. [#36371](https://github.com/ClickHouse/ClickHouse/pull/36371) ([Memo](https://github.com/Joeywzr)).
* temporary table can show total rows and total bytes. [#36401](https://github.com/ClickHouse/ClickHouse/issues/36401). [#36439](https://github.com/ClickHouse/ClickHouse/pull/36439) ([xiedeyantu](https://github.com/xiedeyantu)).
* Added new hash function - wyHash64. [#36467](https://github.com/ClickHouse/ClickHouse/pull/36467) ([olevino](https://github.com/olevino)).
* Window function nth_value was added. [#36601](https://github.com/ClickHouse/ClickHouse/pull/36601) ([Nikolay](https://github.com/ndchikin)).
* Add MySQLDump input format. It reads all data from INSERT queries belonging to one table in dump. If there are more than one table, by default it reads data from the first one. [#36667](https://github.com/ClickHouse/ClickHouse/pull/36667) ([Kruglov Pavel](https://github.com/Avogar)).
* New single binary based diagnostics tool. [#36705](https://github.com/ClickHouse/ClickHouse/pull/36705) ([Dale McDiarmid](https://github.com/gingerwizard)).
* **Description:** It is used to count the system table of a request for remote file access, which can help users analyze the causes of performance fluctuations in the scenario of separation of storage and computer. The current system table structure is as follows. When a query reads a segment of a remote file, a record is generated. Read type include **READ_FROM_FS_AND_DOWNLOADED_TO_CACHE、READ_FROM_CACHE、READ_FROM_FS_BYPASSING_CACHE**, which used to indicate whether the query accesses the segment from the cache or from a remote file. [#36802](https://github.com/ClickHouse/ClickHouse/pull/36802) ([Han Shukai](https://github.com/KinderRiven)).
* Adds `h3Line`, `h3Distance` and `h3HexRing` functions. [#37030](https://github.com/ClickHouse/ClickHouse/pull/37030) ([Bharat Nallan](https://github.com/bharatnc)).
* Related issue - [#35101](https://github.com/ClickHouse/ClickHouse/issues/35101). [#37033](https://github.com/ClickHouse/ClickHouse/pull/37033) ([qieqieplus](https://github.com/qieqieplus)).
* Added system.certificates table. [#37142](https://github.com/ClickHouse/ClickHouse/pull/37142) ([Yakov Olkhovskiy](https://github.com/yakov-olkhovskiy)).
#### Performance Improvement
* Improve performance or ORDER BY, MergeJoin, insertion into MergeTree using JIT compilation of sort columns comparator. [#34469](https://github.com/ClickHouse/ClickHouse/pull/34469) ([Maksim Kita](https://github.com/kitaisreal)).
* First commit is to increase the inline threshold. Next commits will improve queries by inlining for those who have shown better performance. This way we will not increase the compile time and binary size and optimize the program. [#34544](https://github.com/ClickHouse/ClickHouse/pull/34544) ([Daniel Kutenin](https://github.com/danlark1)).
* Transform OR LIKE chain to multiMatchAny. Will enable once we have more confidence it works. [#34932](https://github.com/ClickHouse/ClickHouse/pull/34932) ([Daniel Kutenin](https://github.com/danlark1)).
* Rewrite 'select countDistinct(a) from t' to 'select count(1) from (select a from t groupBy a)'. [#35993](https://github.com/ClickHouse/ClickHouse/pull/35993) ([zhanglistar](https://github.com/zhanglistar)).
* Change structure of `system.asynchronous_metric_log`. It will take about 10 times less space. This closes [#36357](https://github.com/ClickHouse/ClickHouse/issues/36357). The field `event_time_microseconds` was removed, because it is useless. [#36360](https://github.com/ClickHouse/ClickHouse/pull/36360) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* The default `HashJoin` is not thread safe for inserting right table's rows and run it in a single thread. When the right table is large, the join process is too slow with low cpu utilization. [#36415](https://github.com/ClickHouse/ClickHouse/pull/36415) ([lgbo](https://github.com/lgbo-ustc)).
* Improve performance of reading from storage `File` and table functions `file` in case when path has globs and matched directory contains large number of files. [#36647](https://github.com/ClickHouse/ClickHouse/pull/36647) ([Anton Popov](https://github.com/CurtizJ)).
* Appy parallel parsing for input format `HiveText`, which can speed up HiveText parsing by 2x when reading local file. [#36650](https://github.com/ClickHouse/ClickHouse/pull/36650) ([李扬](https://github.com/taiyang-li)).
* Improves performance of file descriptor cache by narrowing mutex scopes. [#36682](https://github.com/ClickHouse/ClickHouse/pull/36682) ([Anton Kozlov](https://github.com/tonickkozlov)).
* This PR improves the `WATCH` query in WindowView: 1. Reduce the latency of providing query results by calling the `fire_condition` signal. 2. Makes the cancel query operation(ctrl-c) faster, by checking `isCancelled()` more frequently. [#37226](https://github.com/ClickHouse/ClickHouse/pull/37226) ([vxider](https://github.com/Vxider)).
* Improve performance of `avg`, `sum` aggregate functions if used without GROUP BY expression. [#37257](https://github.com/ClickHouse/ClickHouse/pull/37257) ([Maksim Kita](https://github.com/kitaisreal)).
* Improve performance of unary arithmetic functions (`bitCount`, `bitNot`, `abs`, `intExp2`, `intExp10`, `negate`, `roundAge`, `roundDuration`, `roundToExp2`, `sign`) using dynamic dispatch. [#37289](https://github.com/ClickHouse/ClickHouse/pull/37289) ([Maksim Kita](https://github.com/kitaisreal)).
#### Improvement
* Remind properly if use clickhouse-client --file without preceeding --external. Close [#34747](https://github.com/ClickHouse/ClickHouse/issues/34747). [#34765](https://github.com/ClickHouse/ClickHouse/pull/34765) ([李扬](https://github.com/taiyang-li)).
* Added support for specifying `content_type` in predefined and static HTTP handler config. [#34916](https://github.com/ClickHouse/ClickHouse/pull/34916) ([Roman Nikonov](https://github.com/nic11)).

* Nullables detection in protobuf using Google wrappers. [#35149](https://github.com/ClickHouse/ClickHouse/pull/35149) ([Jakub Kuklis](https://github.com/jkuklis)).
* If the required amount of memory is available before the selected query stopped, all waiting queries continue execution. Now we don't stop any query if memory is freed before the moment when the selected query knows about the cancellation. [#35637](https://github.com/ClickHouse/ClickHouse/pull/35637) ([Dmitry Novik](https://github.com/novikd)).
* Enable memory overcommit by default. [#35921](https://github.com/ClickHouse/ClickHouse/pull/35921) ([Dmitry Novik](https://github.com/novikd)).

* Add support for force recovery which allows you to reconfigure cluster without quorum. [#36258](https://github.com/ClickHouse/ClickHouse/pull/36258) ([Antonio Andelic](https://github.com/antonio2368)).
* We create a local interpreter if we want to execute query on localhost replica. But for when executing query on multiple replicas we rely on the fact that a connection exists so replicas can talk to coordinator. It is now improved and localhost replica can talk to coordinator directly in the same process. [#36281](https://github.com/ClickHouse/ClickHouse/pull/36281) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Show names of erroneous files in case of parsing errors while executing table functions `file`, `s3` and `url`. [#36314](https://github.com/ClickHouse/ClickHouse/pull/36314) ([Anton Popov](https://github.com/CurtizJ)).
* Allowed to increase the number of threads for executing background operations (merges, mutations, moves and fetches) at runtime if they are specified at top level config. [#36425](https://github.com/ClickHouse/ClickHouse/pull/36425) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).

* Allow names of tuple elements that start from digits. [#36544](https://github.com/ClickHouse/ClickHouse/pull/36544) ([Anton Popov](https://github.com/CurtizJ)).
* Allow file descriptors in table function file if it is run in clickhouse-local. [#36562](https://github.com/ClickHouse/ClickHouse/pull/36562) ([wuxiaobai24](https://github.com/wuxiaobai24)).
* Allow to cast columns of type `Object(...)` to `Object(Nullable(...))`. [#36564](https://github.com/ClickHouse/ClickHouse/pull/36564) ([awakeljw](https://github.com/awakeljw)).
* Cleanup CSS in Play UI. The pixels are more evenly placed. Better usability for long content in table cells. [#36569](https://github.com/ClickHouse/ClickHouse/pull/36569) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* The metrics about time spent reading from s3 now calculated correctly. Close [#35483](https://github.com/ClickHouse/ClickHouse/issues/35483). [#36572](https://github.com/ClickHouse/ClickHouse/pull/36572) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Improve `SYSTEM DROP FILESYSTEM CACHE` query: `<path>` option and `FORCE` option. [#36639](https://github.com/ClickHouse/ClickHouse/pull/36639) ([Kseniia Sumarokova](https://github.com/kssenii)).
* Add `is_all_data_sent` column into `system.processes`, and improve internal testing hardening check based on it. [#36649](https://github.com/ClickHouse/ClickHouse/pull/36649) ([Azat Khuzhin](https://github.com/azat)).
* Now date time conversion functions that generates time before 1970-01-01 00:00:00 with partial hours/minutes timezones will be saturated to zero instead of overflow. This is the continuation of https://github.com/ClickHouse/ClickHouse/pull/29953 which addresses https://github.com/ClickHouse/ClickHouse/pull/29953#discussion_r800550280 . Mark as improvement because it's implementation defined behavior (and very rare case) and we are allowed to break it. [#36656](https://github.com/ClickHouse/ClickHouse/pull/36656) ([Amos Bird](https://github.com/amosbird)).
* Allow to cancel query while still keep decent query id in MySQLHandler. [#36699](https://github.com/ClickHouse/ClickHouse/pull/36699) ([Amos Bird](https://github.com/amosbird)).

* Allow cluster macro in s3Cluster table function. [#36726](https://github.com/ClickHouse/ClickHouse/pull/36726) ([Vadim Volodin](https://github.com/PolyProgrammist)).
* Added `user_defined_path` config setting. [#36753](https://github.com/ClickHouse/ClickHouse/pull/36753) ([Maksim Kita](https://github.com/kitaisreal)).
* Allow to execute hash functions with arguments of type `Array(Tuple(..))`. [#36812](https://github.com/ClickHouse/ClickHouse/pull/36812) ([Anton Popov](https://github.com/CurtizJ)).
* Add warning if someone running clickhouse-server with log level "test". The log level "test" was added recently and cannot be used in production due to inevitable, unavoidable, fatal and life-threatening performance degradation. [#36824](https://github.com/ClickHouse/ClickHouse/pull/36824) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Play UI: If there is one row in result and more than a few columns, display the result vertically. Continuation of [#36811](https://github.com/ClickHouse/ClickHouse/issues/36811). [#36842](https://github.com/ClickHouse/ClickHouse/pull/36842) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Add extra diagnostic info (if applicable) when sending exception to other server. [#36872](https://github.com/ClickHouse/ClickHouse/pull/36872) ([Alexander Tokmakov](https://github.com/tavplubix)).
* After [#36425](https://github.com/ClickHouse/ClickHouse/issues/36425) settings like `background_fetches_pool_size` became obsolete and can appear in top level config, but clickhouse throws and exception like `Error updating configuration from '/etc/clickhouse-server/config.xml' config.: Code: 137. DB::Exception: A setting 'background_fetches_pool_size' appeared at top level in config /etc/clickhouse-server/config.xml.` This is fixed. [#36917](https://github.com/ClickHouse/ClickHouse/pull/36917) ([Nikita Mikhaylov](https://github.com/nikitamikhaylov)).
* Finalize write buffers in case of exception to avoid doing it in destructors. Hope it fixes: [#36907](https://github.com/ClickHouse/ClickHouse/issues/36907). [#36979](https://github.com/ClickHouse/ClickHouse/pull/36979) ([Kruglov Pavel](https://github.com/Avogar)).
* Play UI: Nullable numbers will be aligned to the right in table cells. This closes [#36982](https://github.com/ClickHouse/ClickHouse/issues/36982). [#36988](https://github.com/ClickHouse/ClickHouse/pull/36988) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Implemented a new mode of handling row policies which can be enabled in the main configuration which enables users without permissive row policies to read rows. [#36997](https://github.com/ClickHouse/ClickHouse/pull/36997) ([Vitaly Baranov](https://github.com/vitlibar)).
* Fix bug which can lead to forgotten outdated parts in MergeTree table engines family in case of filesystem failures during parts removal. Before fix they will be removed only after first server restart. [#37014](https://github.com/ClickHouse/ClickHouse/pull/37014) ([alesapin](https://github.com/alesapin)).
* Modify query div in play.html to be extendable beyond 200px height. In case of very long queries it is helpful to extend the textarea element, only today, since the div is fixed height, the extended textarea hides the data div underneath. With this fix, extending the textarea element will push the data div down/up such the extended textarea won't hide it. [#37051](https://github.com/ClickHouse/ClickHouse/pull/37051) ([guyco87](https://github.com/guyco87)).

* Disable `log_query_threads` setting by default. It controls the logging of statistics about every thread participating in query execution. After supporting asynchronous reads, the total number of distinct thread ids became too large, and logging into the `query_thread_log` has become too heavy. [#37077](https://github.com/ClickHouse/ClickHouse/pull/37077) ([Alexey Milovidov](https://github.com/alexey-milovidov)).
* Option `compatibility_ignore_auto_increment_in_create_table` allows ignoring `AUTO_INCREMENT` keyword in a column declaration to simplify migration from MySQL. [#37178](https://github.com/ClickHouse/ClickHouse/pull/37178) ([Igor Nikonov](https://github.com/devcrafter)).
* Added implicit cast for `h3kRing` function second argument to improve usability. Closes [#35432](https://github.com/ClickHouse/ClickHouse/issues/35432). [#37189](https://github.com/ClickHouse/ClickHouse/pull/37189) ([Maksim Kita](https://github.com/kitaisreal)).

#### Bug Fix
* Extracts Version ID if present from the URI and adds a request to the AWS HTTP URI. Closes [#31221](https://github.com/ClickHouse/ClickHouse/issues/31221). - [x] Extract `Version ID` from URI if present and reassemble without it. - [x] Configure `AWS HTTP URI` object with request. - [x] Unit Tests: [`gtest_s3_uri`](https://github.com/ClickHouse/ClickHouse/blob/2340a6c6849ebc05a8efbf97ba8de3ff9dc0eff4/src/IO/tests/gtest_s3_uri.cpp) - [x] Drop instrumentation commit.

* In the previous [PR](https://github.com/ClickHouse/ClickHouse/pull/36376), I found that testing **(stateless tests, flaky check (address, actions))** is timeout. Moreover, testing locally can also trigger unstable system deadlocks. This problem still exists when using the latest source code of master. [#36697](https://github.com/ClickHouse/ClickHouse/pull/36697) ([Han Shukai](https://github.com/KinderRiven)).
* Fix server reload on port change (do not wait for current connections from query context). [#36700](https://github.com/ClickHouse/ClickHouse/pull/36700) ([Azat Khuzhin](https://github.com/azat)).
* Fix vertical merges in wide parts. Previously an exception `There is no column` can be thrown during merge. [#36707](https://github.com/ClickHouse/ClickHouse/pull/36707) ([Anton Popov](https://github.com/CurtizJ)).

Although the cause of this problem is not clear, there should be code logic of repeatedly loading disk in ClickHouse, so we need to make special judgment for this situation.

Each functional test sends one or multiple queries to the running ClickHouse server and compares the result with reference.
Tests are located in `queries` directory. There are two subdirectories: `stateless` and `stateful`. Stateless tests run queries without any preloaded test data - they often create small synthetic datasets on the fly, within the test itself. Stateful tests require preloaded test data from CLickHouse and it is available to general public.

Stateless tests run queries without any preloaded test data - they often create small synthetic datasets on the fly, within the test itself. Stateful tests require preloaded test data from ClickHouse and it is available to general public.
Each test can be one of two types: `.sql` and `.sh`. `.sql` test is the simple SQL script that is piped to `clickhouse-client --multiquery`. `.sh` test is a script that is run by itself. SQL tests are generally preferable to `.sh` tests. You should use `.sh` tests only when you have to test some feature that cannot be exercised from pure SQL, such as piping some input data into `clickhouse-client` or testing `clickhouse-local`.

- `max_data_part_size_bytes` — the maximum size of a part that can be stored on any of the volume’s disks. If the a size of a merged part estimated to be bigger than `max_data_part_size_bytes` then this part will be written to a next volume. Basically this feature allows to keep new/small parts on a hot (SSD) volume and move them to a cold (HDD) volume when they reach large size. Do not use this setting if your policy has only one volume.
- `move_factor` — when the amount of available space gets lower than this factor, data automatically starts to move on the next volume if any (by default, 0.1). ClickHouse sorts existing parts by size from largest to smallest (in descending order) and selects parts with the total size that is sufficient to meet the `move_factor` condition. If the total size of all parts is insufficient, all parts will be moved.
- `prefer_not_to_merge` — Disables merging of data parts on this volume. When this setting is enabled, merging data on this volume is not allowed. This allows controlling how ClickHouse works with slow disks.
- `perform_ttl_move_on_insert` — Disables TTL move on data part INSERT. By default if we insert a data part that already expired by the TTL move rule it immediately goes to a volume/disk declared in move rule. This can significantly slowdown insert in case if destination volume/disk is slow (e.g. S3).

Since https://github.com/ClickHouse/ClickHouse/commit/4076ae77b46794e73594a9f400200088ed1e7a6e , there be a separate type for boolean values.
Type `bool` is stored as UInt8. Possible values `true` (1), `false` (0).
For versions before that, there is no separate type for boolean values. Use UInt8 type, restricted to the values 0 or 1.

# JSON {#json-data-type}
Stores JavaScript Object Notation (JSON) documents in a single column.
`JSON` is an alias for `Object('json')`.
:::warning
The JSON data type is an experimental feature. To use it, set `allow_experimental_object_type = 1`.
:::
## Example {#usage-example}
**Example 1**
Creating a table with a `JSON` column and inserting data into it:
```sql
CREATE TABLE json
(
o JSON
)
ENGINE = Memory
```
```sql
INSERT INTO json VALUES ('{"a": 1, "b": { "c": 2, "d": [1, 2, 3] }}')
```
```sql
SELECT o.a, o.b.c, o.b.d[3] FROM json
```
```text
┌─o.a─┬─o.b.c─┬─arrayElement(o.b.d, 3)─┐
│ 1 │ 2 │ 3 │
└─────┴───────┴────────────────────────┘
```
**Example 2**
To be able to create an ordered `MergeTree` family table the sorting key has to be extracted into its column. For example, to insert a file of compressed HTTP access logs in JSON format:
```sql
CREATE TABLE logs
(
timestamp DateTime,
message JSON
)
ENGINE = MergeTree
ORDER BY timestamp
```
```sql
INSERT INTO logs
SELECT parseDateTimeBestEffort(JSONExtractString(json, 'timestamp')), json
FROM file('access.json.gz', JSONAsString)
```
## Displaying JSON columns
When displaying a `JSON` column ClickHouse only shows the field values by default (because internally, it is represented as a tuple). You can display the field names as well by setting `output_format_json_named_tuples_as_objects = 1`:
```sql
SET output_format_json_named_tuples_as_objects = 1
SELECT * FROM json FORMAT JSONEachRow
```
```text
{"o":{"a":1,"b":{"c":2,"d":[1,2,3]}}}
```

# Можно ли использовать ClickHouse как базу данных временных рядов? {#can-i-use-clickhouse-as-a-time-series-database}
ClickHouse — это универсальное решение для [OLAP](../../faq/general/olap.md) операций, в то время как существует много специализированных СУБД временных рядов. Однако [высокая скорость выполнения запросов](../../faq/general/why-clickhouse-is-so-fast.md) позволяет CLickHouse во многих случаях "побеждать" специализированные аналоги. В подтверждение этому есть много примеров с конкретными показателями производительности, так что мы не будем останавливаться на этом подробно. Лучше рассмотрим те возможности ClickHouse, которые стоит использовать.

## hex {#hex}
接受`String`，`unsigned integer`，`Date`或`DateTime`类型的参数。返回包含参数的十六进制表示的字符串。使用大写字母`A-F`。不使用`0x`前缀或`h`后缀。对于字符串，所有字节都简单地编码为两个十六进制数字。数字转换为大端（«易阅读»）格式。对于数字，去除其中较旧的零，但仅限整个字节。例如，`hex（1）='01'`。 `Date`被编码为自Unix时间开始以来的天数。 `DateTime`编码为自Unix时间开始以来的秒数。
返回包含参数的十六进制表示的字符串。
## unhex(str) {#unhexstr}
别名为： `HEX`。
接受包含任意数量的十六进制数字的字符串，并返回包含相应字节的字符串。支持大写和小写字母A-F。十六进制数字的数量不必是偶数。如果是奇数，则最后一位数被解释为00-0F字节的低位。如果参数字符串包含除十六进制数字以外的任何内容，则返回一些实现定义的结果（不抛出异常）。
如果要将结果转换为数字，可以使用«reverse»和«reinterpretAsType»函数。
**语法**
``` sql

```
该函数使用大写字母`A-F`，不使用任何前缀（如`0x`）或后缀（如`h`）
对于整数参数，它从高到低（大端或“人类可读”顺序）打印十六进制数字（“半字节”）。它从左侧第一个非零字节开始（省略前导零字节），但即使前导数字为零，也始终打印每个字节的两个数字。
类型为[Date](../../sql-reference/data-types/date.md)和[DateTime](../../sql-reference/data-types/datetime.md)的值将被格式化为相应的整数（日期为 Epoch 以来的天数，DateTime 为 Unix Timestamp 的值）。
对于[String](../../sql-reference/data-types/string.md)和[FixedString](../../sql-reference/data-types/fixedstring.md)，所有字节都被简单地编码为两个十六进制数字。零字节不会被省略。
类型为[Float](../../sql-reference/data-types/float.md)和[Decimal](../../sql-reference/data-types/decimal.md)的值被编码为它们在内存中的表示。由于我们支持小端架构，它们以小端编码。零前导尾随字节不会被省略。

## unhex {#unhexstr}
执行[hex](#hex)函数的相反操作。它将每对十六进制数字（在参数中）解释为一个数字，并将其转换为该数字表示的字节。返回值是一个二进制字符串 (BLOB)。
如果要将结果转换为数字，可以使用 [reverse](../../sql-reference/functions/string-functions.md#reverse) 和 [reinterpretAs&lt;Type&gt;](../../sql-reference/functions/type-conversion-functions.md#type-conversion-functions) 函数。
:::注意
如果从 `clickhouse-client` 中调用 `unhex`，二进制字符串将使用 UTF-8 显示。
:::
别名为：`UNHEX`。
**语法**
``` sql
unhex(arg)
```
**参数**
- `arg` — 包含任意数量的十六进制数字的字符串。类型为：[String](../../sql-reference/data-types/string.md)。
支持大写和小写字母A-F。十六进制数字的数量不必是偶数。如果是奇数，则最后一位数被解释为00-0F字节的低位。如果参数字符串包含除十六进制数字以外的任何内容，则返回一些实现定义的结果（不抛出异常）。对于数字参数， unhex()不执行 hex(N) 的倒数。
**返回值**
- 二进制字符串 (BLOB)。
类型为： [String](../../sql-reference/data-types/string.md)。
**示例**
查询语句：
``` sql
SELECT unhex('303132'), UNHEX('4D7953514C');
```
结果：
``` text
┌─unhex('303132')─┬─unhex('4D7953514C')─┐
│ 012 │ MySQL │
└─────────────────┴─────────────────────┘
```
查询语句：
``` sql
SELECT reinterpretAsUInt64(reverse(unhex('FFF'))) AS num;
```
结果：
``` text
┌──num─┐
│ 4095 │
└──────┘
```
## bin {#bin}
返回一个包含参数二进制表示的字符串。
**语法**
``` sql
bin(arg)
```
别名为： `BIN`。
对于整数参数，它从最高有效到最低有效（大端或“人类可读”顺序）打印 bin 数字。它从最重要的非零字节开始（省略前导零字节），但如果前导数字为零，则始终打印每个字节的八位数字。
类型为[Date](../../sql-reference/data-types/date.md)和[DateTime](../../sql-reference/data-types/datetime.md)的值被格式化为相应的整数（`Date` 为 Epoch 以来的天数，`DateTime` 为 Unix Timestamp 的值）。
对于[String](../../sql-reference/data-types/string.md)和[FixedString](../../sql-reference/data-types/fixedstring.md)，所有字节都被简单地编码为八个二进制数。零字节不会被省略。
类型为[Float](../../sql-reference/data-types/float.md)和[Decimal](../../sql-reference/data-types/decimal.md)的值被编码为它们在内存中的表示。由于我们支持小端架构，它们以小端编码。零前导尾随字节不会被省略。
类型为[UUID](../data-types/uuid.md)的值被编码为大端顺序字符串。
**参数**
- `arg` — 要转换为二进制的值。类型为[String](../../sql-reference/data-types/string.md)，[FixedString](../../sql-reference/data-types/fixedstring.md)，[UInt](../../sql-reference/data-types/int-uint.md)，[Float](../../sql-reference/data-types/float.md)，[Decimal](../../sql-reference/data-types/decimal.md)，[Date](../../sql-reference/data-types/date.md)或者[DateTime](../../sql-reference/data-types/datetime.md)。
**返回值**
- 具有参数的二进制表示的字符串。
类型为： [String](../../sql-reference/data-types/string.md)。
**示例**
查询语句：
``` sql
SELECT bin(14);
```
结果：
``` text
┌─bin(14)──┐
│ 00001110 │

## unbin {#unbinstr}
将每对二进制数字（在参数中）解释为一个数字，并将其转换为该数字表示的字节。这些函数执行与 [bin](#bin) 相反的操作。
**语法**
``` sql
unbin(arg)
```
别名为： `UNBIN`。
对于数字参数，`unbin()` 不会返回 `bin()` 的倒数。如果要将结果转换为数字，可以使用[reverse](../../sql-reference/functions/string-functions.md#reverse) 和 [reinterpretAs&lt;Type&gt;](../../sql-reference/functions/type-conversion-functions.md#reinterpretasuint8163264) 函数。
:::note
如果从 `clickhouse-client` 中调用 `unbin`，则使用 UTF-8 显示二进制字符串。
:::
支持二进制数字`0`和`1`。二进制位数不必是八的倍数。如果参数字符串包含二进制数字以外的任何内容，则返回一些实现定义的结果（不抛出异常）。
**参数**
- `arg` — 包含任意数量的二进制数字的字符串。类型为[String](../../sql-reference/data-types/string.md)。
**返回值**
- 二进制字符串 (BLOB)。
类型为：[String](../../sql-reference/data-types/string.md)。
**示例**
查询语句：
``` sql
