# Map(key, value) {#data_type-map}
|
||||
|
||||
`Map(key, value)` data type stores `key:value` pairs.
|
||||
|
||||
**Parameters**
|
||||
- `key` — The key part of the pair. [String](../../sql-reference/data-types/string.md) or [Integer](../../sql-reference/data-types/int-uint.md).
|
||||
- `value` — The value part of the pair. [String](../../sql-reference/data-types/string.md), [Integer](../../sql-reference/data-types/int-uint.md) or [Array](../../sql-reference/data-types/array.md).
|
||||
|
||||
!!! warning "Warning"
|
||||
Currently `Map` data type is an experimental feature. To work with it you must set `allow_experimental_map_type = 1`.
|
||||
|
||||
To get the value from an `a Map('key', 'value')` column, use `a['key']` syntax. This lookup works now with a linear complexity.
|
||||
|
||||
**Examples**
|
||||
|
||||
Consider the table:
|
||||
|
||||
``` sql
|
||||
CREATE TABLE table_map (a Map(String, UInt64)) ENGINE=Memory;
|
||||
INSERT INTO table_map VALUES ({'key1':1, 'key2':10}), ({'key1':2,'key2':20}), ({'key1':3,'key2':30});
|
||||
```
|
||||
|
||||
Select all `key2` values:
|
||||
|
||||
```sql
|
||||
SELECT a['key2'] FROM table_map;
|
||||
```
|
||||
Result:
|
||||
|
||||
```text
|
||||
┌─arrayElement(a, 'key2')─┐
|
||||
│ 10 │
|
||||
│ 20 │
|
||||
│ 30 │
|
||||
└─────────────────────────┘
|
||||
```
|
||||
|
||||
If there's no such `key` in the `Map()` column, the query returns zeros for numerical values, empty strings or empty arrays.
|
||||
|
||||
```sql
|
||||
INSERT INTO table_map VALUES ({'key3':100}), ({});
|
||||
SELECT a['key3'] FROM table_map;
|
||||
```
|
||||
|
||||
Result:
|
||||
|
||||
```text
|
||||
┌─arrayElement(a, 'key3')─┐
|
||||

|
||||

```
|
||||
|
||||
## Convert Tuple to Map Type {#map-and-tuple}
|
||||
|
||||
You can cast `Tuple()` as `Map()` using [CAST](../../sql-reference/functions/type-conversion-functions.md#type_conversion_function-cast) function:
|
||||
|
||||
``` sql
|
||||
SELECT CAST(([1, 2, 3], ['Ready', 'Steady', 'Go']), 'Map(UInt8, String)') AS map;
|
||||
```
|
||||

# Map(key, value) {#data_type-map}
|
||||
|
||||
Тип данных `Map(key, value)` хранит пары `ключ:значение`.
|
||||
|
||||
**Параметры**
|
||||
- `key` — ключ. [String](../../sql-reference/data-types/string.md) или [Integer](../../sql-reference/data-types/int-uint.md).
|
||||
- `value` — значение. [String](../../sql-reference/data-types/string.md), [Integer](../../sql-reference/data-types/int-uint.md) или [Array](../../sql-reference/data-types/array.md).
|
||||
|
||||
!!! warning "Предупреждение"
|
||||
Сейчас использование типа данных `Map` является экспериментальной возможностью. Чтобы использовать этот тип данных, включите настройку `allow_experimental_map_type = 1`.
|
||||
|
||||
Чтобы получить значение из колонки `a Map('key', 'value')`, используйте синтаксис `a['key']`. В настоящее время такая подстановка работает по алгоритму с линейной сложностью.
|
||||
|
||||
**Примеры**
|
||||
|
||||
Рассмотрим таблицу:
|
||||
|
||||
``` sql
|
||||
CREATE TABLE table_map (a Map(String, UInt64)) ENGINE=Memory;
|
||||
INSERT INTO table_map VALUES ({'key1':1, 'key2':10}), ({'key1':2,'key2':20}), ({'key1':3,'key2':30});
|
||||
```
|
||||
|
||||
Выборка всех значений ключа `key2`:
|
||||
|
||||
```sql
|
||||
SELECT a['key2'] FROM table_map;
|
||||
```
|
||||
Результат:
|
||||
|
||||
```text
|
||||
┌─arrayElement(a, 'key2')─┐
|
||||
│ 10 │
|
||||
│ 20 │
|
||||
│ 30 │
|
||||
└─────────────────────────┘
|
||||
```
|
||||
|
||||
Если для какого-то ключа `key` в колонке с типом `Map()` нет значения, запрос возвращает нули для числовых колонок, пустые строки или пустые массивы.
|
||||
|
||||
```sql
|
||||
INSERT INTO table_map VALUES ({'key3':100}), ({});
|
||||
SELECT a['key3'] FROM table_map;
|
||||
```
|
||||
|
||||
Результат:
|
||||
|
||||
```text
|
||||
┌─arrayElement(a, 'key3')─┐

||||
