**Parameters**
- `key` — The key part of the pair. [String](../../sql-reference/data-types/string.md), [Integer](../../sql-reference/data-types/int-uint.md), [LowCardinality](../../sql-reference/data-types/lowcardinality.md), or [FixedString](../../sql-reference/data-types/fixedstring.md).
- `value` — The value part of the pair. [String](../../sql-reference/data-types/string.md), [Integer](../../sql-reference/data-types/int-uint.md), [Array](../../sql-reference/data-types/array.md), [LowCardinality](../../sql-reference/data-types/lowcardinality.md), or [FixedString](../../sql-reference/data-types/fixedstring.md).
- `key` — The key part of the pair. [String](../../sql-reference/data-types/string.md), [Integer](../../sql-reference/data-types/int-uint.md), [LowCardinality](../../sql-reference/data-types/lowcardinality.md), [FixedString](../../sql-reference/data-types/fixedstring.md), [UUID](../../sql-reference/data-types/uuid.md), [Date](../../sql-reference/data-types/date.md), [DateTime](../../sql-reference/data-types/datetime.md), [Date32](../../sql-reference/data-types/date32.md), [Enum](../../sql-reference/data-types/enum.md).
- `value` — The value part of the pair. Arbitrary type, including [Map](../../sql-reference/data-types/map.md) and [Array](../../sql-reference/data-types/array.md).
To get the value from an `a Map('key', 'value')` column, use `a['key']` syntax. This lookup works now with a linear complexity.

**Параметры**
- `key` — ключ. [String](../../sql-reference/data-types/string.md), [Integer](../../sql-reference/data-types/int-uint.md), [LowCardinality](../../sql-reference/data-types/lowcardinality.md) или [FixedString](../../sql-reference/data-types/fixedstring.md).
- `value` — значение. [String](../../sql-reference/data-types/string.md), [Integer](../../sql-reference/data-types/int-uint.md), [Array](../../sql-reference/data-types/array.md), [LowCardinality](../../sql-reference/data-types/lowcardinality.md) или [FixedString](../../sql-reference/data-types/fixedstring.md).

- `value` — значение. Любой тип, включая [Map](../../sql-reference/data-types/map.md) и [Array](../../sql-reference/data-types/array.md).
Чтобы получить значение из колонки `a Map('key', 'value')`, используйте синтаксис `a['key']`. В настоящее время такая подстановка работает по алгоритму с линейной сложностью.
