# mysql.tables\_priv Table

1. PARTITION BY SYSTEM\_TIME is not supported for transaction-precise system-versioned tables. Attempting

The `mysql.tables_priv` table contains information about table-level privileges. The table can be queried and although it is possible to directly update it, it is best to use [GRANT](/docs/server/reference/sql-statements/account-management-sql-statements/grant.md) for setting privileges.

Note that the MariaDB privileges occur at many levels. A user may be granted a privilege at the table level, but may still not have permission on a database level, for example. See [privileges](/docs/server/reference/sql-statements/account-management-sql-statements/grant.md) for a more complete view of the MariaDB privilege system.

The [INFORMATION\_SCHEMA.TABLE\_PRIVILEGES](/docs/server/reference/system-tables/information-schema/information-schema-tables/information-schema-table_privileges-table.md) table derives its contents from `mysql.tables_priv`.

This table uses the [Aria](/docs/server/server-usage/storage-engines/aria.md) storage engine.

The `mysql.tables_priv` table contains the following fields:
