### ClickHouse release v24.5.2.34-stable (45589aeee49) FIXME as compared to v24.5.1.1763-stable (647c154a94d)
|
||||
|
||||
#### Improvement
|
||||
* Backported in [#65096](https://github.com/ClickHouse/ClickHouse/issues/65096): The setting `allow_experimental_join_condition` was accidentally marked as important which may prevent distributed queries in a mixed versions cluster from being executed successfully.

By default, tunneling (i.e, `HTTP CONNECT`) is used to make `HTTPS` requests over `HTTP` proxy. This setting can be used to disable it.
|
||||
|
||||
### no_proxy
|
||||
By default, all requests will go through the proxy. In order to disable it for specific hosts, the `no_proxy` variable must be set.
|
||||
It can be set inside the `<proxy>` clause for list and remote resolvers and as an environment variable for environment resolver.
|
||||
It supports IP addresses, domains, subdomains and `'*'` wildcard for full bypass. Leading dots are stripped just like curl does.
|
||||
|

Example:
|
||||
|
||||
The below configuration bypasses proxy requests to `clickhouse.cloud` and all of its subdomains (e.g, `auth.clickhouse.cloud`).
|
||||
The same applies to GitLab, even though it has a leading dot. Both `gitlab.com` and `about.gitlab.com` would bypass the proxy.

This query calculates the sample variance of the `value` column in the `example_table` using the `varSampStable()` function. The result shows that the sample variance of the values `[10.5, 12.3, 9.8, 11.2, 10.7]` is approximately 0.865, which may differ slightly from the result of `varSamp` due to the more precise handling of floating-point arithmetic.

For cache dictionaries, the expiration [lifetime](#dictionary-updates) of data in the cache can be set.

This is the least effective of all the ways to store dictionaries. The speed of the cache depends strongly on correct settings and the usage scenario.

[S2](https://s2geometry.io/) is a geographical indexing system where all geographical data is represented on a three-dimensional sphere (similar to a globe).
|
||||
|
||||
In the S2 library points are represented as the S2 Index - a specific number which encodes internally a point on the surface of a unit sphere, unlike traditional (latitude, longitude) pairs. To get the S2 point index for a given point specified in the format (latitude, longitude) use the [geoToS2](#geotos2) function. Also, you can use the [s2ToGeo](#s2togeo) function for getting geographical coordinates corresponding to the specified S2 point index.

Changing the column type is the only complex action – it changes the contents of files with data. For large tables, this may take a long time.
|

The query also can change the order of the columns using `FIRST | AFTER` clause, see [ADD COLUMN](#alter_add-column) description, but column type is mandatory in this case.

The query does the following:

- Using the keyword `ALL`. It can be used only with DROP/DETACH/ATTACH. For example, `ALTER TABLE visits ATTACH PARTITION ALL`.
|
||||
- As a tuple of expressions or constants that matches (in types) the table partitioning keys tuple. In the case of a single element partitioning key, the expression should be wrapped in the `tuple (...)` function. For example, `ALTER TABLE visits DETACH PARTITION tuple(toYYYYMM(toDate('2019-01-25')))`.
|
||||
- Using the partition ID. Partition ID is a string identifier of the partition (human-readable, if possible) that is used as the names of partitions in the file system and in ZooKeeper. The partition ID must be specified in the `PARTITION ID` clause, in a single quotes. For example, `ALTER TABLE visits DETACH PARTITION ID '201901'`.
|
||||
- In the [ALTER ATTACH PART](#alter_attach-partition) and [DROP DETACHED PART](#alter_drop-detached) query, to specify the name of a part, use string literal with a value from the `name` column of the [system.detached_parts](/docs/en/operations/system-tables/detached_parts.md/#system_tables-detached_parts) table. For example, `ALTER TABLE visits ATTACH PART '201901_1_1_0'`.
|
||||
- In the [ALTER ATTACH PART](#attach-partitionpart) and [DROP DETACHED PART](#drop-detached-partitionpart) query, to specify the name of a part, use string literal with a value from the `name` column of the [system.detached_parts](/docs/en/operations/system-tables/detached_parts.md/#system_tables-detached_parts) table. For example, `ALTER TABLE visits ATTACH PART '201901_1_1_0'`.
|
||||
|
||||
Usage of quotes when specifying the partition depends on the type of partition expression. For example, for the `String` type, you have to specify its name in quotes (`'`). For the `Date` and `Int*` types no quotes are needed.
