**Parameters**
- `window` — Length of the sliding window in seconds.
- `window` — Length of the sliding window. The unit of `window` depends on the timestamp itself and varies. Determined using the expression `timestamp of cond2 <= timestamp of cond1 + window`.
- `mode` - It is an optional argument.
- `'strict'` - When the `'strict'` is set, the windowFunnel() applies conditions only for the unique values.
- `timestamp` — Name of the column containing the timestamp. Data types supported: [Date](../../sql-reference/data-types/date.md), [DateTime](../../sql-reference/data-types/datetime.md#data_type-datetime) and other unsigned integer types (note that even though timestamp supports the `UInt64` type, it’s value can’t exceed the Int64 maximum, which is 2^63 - 1).

## aes_encrypt_mysql {#aes_encrypt_mysql}
Compatible with mysql encryption and can be decrypted with [AES_DECRYPT](https://dev.mysql.com/doc/refman/8.0/en/encryption-functions.html#function_aes-decrypt) function.
Compatible with mysql encryption and resulting ciphertext can be decrypted with [AES_DECRYPT](https://dev.mysql.com/doc/refman/8.0/en/encryption-functions.html#function_aes-decrypt) function.
Will produce same ciphertext as `encrypt` on equal inputs. But when `key` or `iv` are longer than they should normally be, `aes_encrypt_mysql` will stick to what MySQL's `aes_encrypt` does: 'fold' `key` and ignore excess bits of `IV`.

## aes_decrypt_mysql {#aes_decrypt_mysql}
Compatible with mysql encryption and decrypts data encrypted with [AES_ENCRYPT](https://dev.mysql.com/doc/refman/8.0/en/encryption-functions.html#function_aes-encrypt) function.
Will produce same plaintext as `decrypt` on equal inputs. But when `key` or `iv` are longer than they should normally be, `aes_decrypt_mysql` will stick to what MySQL's `aes_decrypt` does: 'fold' `key` and ignore excess bits of `IV`.
Supported decryption modes:
- aes-128-ecb, aes-192-ecb, aes-256-ecb

# Движок EmbeddedRocksDB {#EmbeddedRocksDB-engine}
Этот движок позволяет интегрировать ClickHouse с [rocksdb](http://rocksdb.org/).
## Создание таблицы {#table_engine-EmbeddedRocksDB-creating-a-table}
``` sql
CREATE TABLE [IF NOT EXISTS] [db.]table_name [ON CLUSTER cluster]
(
name1 [type1] [DEFAULT|MATERIALIZED|ALIAS expr1],
name2 [type2] [DEFAULT|MATERIALIZED|ALIAS expr2],
...
) ENGINE = EmbeddedRocksDB
PRIMARY KEY(primary_key_name);
```
Обязательные параметры:
- `primary_key_name` может быть любое имя столбца из списка столбцов.
- Указание первичного ключа `primary key` является обязательным. Он будет сериализован в двоичном формате как ключ `rocksdb`.
- Поддерживается только один столбец в первичном ключе.
- Столбцы, которые отличаются от первичного ключа, будут сериализованы в двоичном формате как значение `rockdb` в соответствующем порядке.
- Запросы с фильтрацией по ключу `equals` или `in` оптимизируются для поиска по нескольким ключам из `rocksdb`.
Пример:
``` sql
CREATE TABLE test
(
`key` String,
`v1` UInt32,
`v2` String,
`v3` Float32,
)
ENGINE = EmbeddedRocksDB
PRIMARY KEY key;
```

Консольный клиент ClickHouse по умолчанию использует часовой пояс сервера, если для значения `DateTime` часовой пояс не был задан в явном виде при инициализации типа данных. Чтобы использовать часовой пояс клиента, запустите [clickhouse-client](../../interfaces/cli.md) с параметром `--use_client_time_zone`.
ClickHouse отображает значения типа `DateTime` в формате `YYYY-MM-DD hh:mm:ss`. Отображение можно поменять с помощью функции [formatDateTime](../../sql-reference/data-types/datetime.md#formatdatetime).
