All tables are renamed under global locking. Renaming tables is a light operation. If you indicated another 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).
## SET
## SET {#query-set}
``` sql
```sql
SET param = value
```
Allows you to set `param` to `value`. You can also make all the settings from the specified settings profile in a single query. To do this, specify 'profile' as the setting name. For more information, see the section "Settings".
The setting is made for the session, or for the server (globally) if `GLOBAL` is specified.
When making a global setting, the setting is not applied to sessions already running, including the current session. It will only be used for new sessions.
Assigns `value` to the `param` configurations settings for the current session. You cannot change [server settings](../operations/server_settings/index.md) this way.
When the server is restarted, global settings made using `SET` are lost.
To make settings that persist after a server restart, you can only use the server's config file.
You can also set all the values from the specified settings profile in a single query.
```sql
SET profile = 'profile-name-from-the-settings-file'
```
For more information, see [Settings](../operations/settings/settings.md).
