# RENAME Statement
|
|
|
|
Renames databases, tables, or dictionaries. Several entities can be renamed in a single query.
|
|
Note that the `RENAME` query with several entities is non-atomic operation. To swap entities names atomically, use the [EXCHANGE](./exchange.md) statement.
|
|
|
|
:::note
|
|
The `RENAME` query is supported by the [Atomic](../../engines/database-engines/atomic.md) database engine only.

**Syntax**
|
|
|
|
```sql
|
|
RENAME DATABASE|TABLE|DICTIONARY name TO new_name [,...] [ON CLUSTER cluster]
|
|
```
|
|
|
|
## RENAME DATABASE
|
|
|
|
Renames databases.
|
|
|
|
**Syntax**
|
|
|
|
```sql
|
|
RENAME DATABASE atomic_database1 TO atomic_database2 [,...] [ON CLUSTER cluster]
|
|
```
|
|
|
|
## RENAME TABLE
|
|
|
|
Renames one or more tables.
|
|
|
|
Renaming tables is a light operation. If you pass a different database after `TO`, the table will be moved to this database. However, the directories with databases must reside in the same file system. Otherwise, an error is returned.
|
|
If you rename multiple tables in one query, the operation is not atomic. It may be partially executed, and queries in other sessions may get `Table ... does not exist ...` error.
|
|
|
|
**Syntax**
|
|
|
|
``` sql
|
|
RENAME TABLE [db1.]name1 TO [db2.]name2 [,...] [ON CLUSTER cluster]
|
|
```
|
|
|
|
**Example**
|
|
|
|
```sql
|
|
RENAME TABLE table_A TO table_A_bak, table_B TO table_B_bak;
|
|
```
|
|
|
|
## RENAME DICTIONARY
|
|
|
|
Renames one or several dictionaries. This query can be used to move dictionaries between databases.
|
|
|
|
**Syntax**
|
|
|
|
```sql
|
|
RENAME DICTIONARY [db0.]dict_A TO [db1.]dict_B [,...] [ON CLUSTER cluster]
|
|
```
