Default value - `false`.
## BSONEachRow {#bsoneachrow}
In this format, ClickHouse formats/parses data as a sequence of BSON documents without any separator between them.
Each row is formatted as a single document and each column is formatted as a single BSON document field with column name as a key.
For output it uses the following correspondence between ClickHouse types and BSON types:

Other BSON types are not supported. Also, it performs conversion between different integer types (for example, you can insert BSON int32 value into ClickHouse UInt8).
Big integers and decimals (Int128/UInt128/Int256/UInt256/Decimal128/Decimal256) can be parsed from BSON Binary value with `\x00` binary subtype. In this case this format will validate that the size of binary data equals the size of expected value.
Note: this format don't work properly on Big-Endian platforms.
### BSON format settings {#bson-format-settings}
- [output_format_bson_string_as_string](../operations/settings/settings.md#output_format_bson_string_as_string) - use BSON String type instead of Binary for String columns. Default value - `false`.
- [input_format_bson_skip_fields_with_unsupported_types_in_schema_inference](../operations/settings/settings.md#input_format_bson_skip_fields_with_unsupported_types_in_schema_inference) - allow skipping columns with unsupported types while schema inference for format BSONEachRow. Default value - `false`.
## Native {#native}
The most efficient format. Data is written and read by blocks in binary format. For each block, the number of rows, number of columns, column names and types, and parts of columns in this block are recorded one after another. In other words, this format is “columnar” it does not convert columns to rows. This is the format used in the native interface for interaction between servers, for using the command-line client, and for C++ clients.

You can define one or more projections for a table, and during the query analysis the projection with the least data to scan will be selected by ClickHouse without modifying the query provided by the user.
:::note Disk usage
Projections will create internally a new hidden table, this means that more IO and space on disk will be required.
Example, If the projection has defined a different primary key, all the data from the original table will be duplicated.
:::
You can see more technical details about how projections work internally on this [page](/docs/en/guides/improving-query-performance/sparse-primary-indexes/sparse-primary-indexes-multiple.md/#option-3-projections).

A `SELECT` query can contain `DISTINCT`, `GROUP BY`, `ORDER BY`, `LIMIT`. Note that the corresponding conversions are performed independently on each block of inserted data. For example, if `GROUP BY` is set, data is aggregated during insertion, but only within a single packet of inserted data. The data wont be further aggregated. The exception is when using an `ENGINE` that independently performs data aggregation, such as `SummingMergeTree`.
The execution of [ALTER](../../../sql-reference/statements/alter/view.md) queries on materialized views has limitations, so they might be inconvenient. If the materialized view uses the construction `TO [db.]name`, you can `DETACH` the view, run `ALTER` for the target table, and then `ATTACH` the previously detached (`DETACH`) view.

You can use `WITH TOTALS` in subqueries, including subqueries in the [JOIN](../../../sql-reference/statements/select/join.md) clause (in this case, the respective total values are combined).
## GROUP BY ALL
`GROUP BY ALL` is equivalent to listing all the SELECT-ed expressions that are not aggregate functions.
For example:
``` sql
SELECT
a * 2,
b,
count(c),
FROM t
GROUP BY ALL
```
is the same as
``` sql
SELECT
a * 2,
b,
count(c),
FROM t
GROUP BY a * 2, b
```
For a special case that if there is a function having both aggregate functions and other fields as its arguments, the `GROUP BY` keys will contain the maximum non-aggregate fields we can extract from it.
For example:
``` sql
SELECT
substring(a, 4, 2),
substring(substring(a, 1, 2), 1, count(b))
FROM t
GROUP BY ALL
```
is the same as
``` sql
SELECT
substring(a, 4, 2),
substring(substring(a, 1, 2), 1, count(b))
FROM t
GROUP BY substring(a, 4, 2), substring(a, 1, 2)
```
