# mysql.db Table
The `mysql.db` table contains information about database-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 not be granted a privilege at the database level, but may still have permission on a table 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.
This table uses the [Aria](/docs/server/server-usage/storage-engines/aria.md) storage engine.
The `mysql.db` table contains the following fields:
| Field | Type | Null | Key | Default | Description |
| ------------------------ | ------------- | ---- | --- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Host | char(60) | NO | PRI | | Host (together with User and Db makes up the unique identifier for this record. Until MariaDB 5.5, if the host field was blank, the corresponding record in the [mysql.host](/docs/server/reference/system-tables/the-mysql-database-tables/obsolete-mysql-database-tables/mysql-host-table.md) table would be examined. From MariaDB 10.0, a blank host field is the same as the % wildcard. |
| Db | char(64) | NO | PRI | | Database (together with User and Host makes up the unique identifier for this record. |
| User | char(80) | NO | PRI | | User (together with Host and Db makes up the unique identifier for this record. |

| Index\_priv | enum('N','Y') | NO | | N | Can create an index on a table using the [CREATE INDEX](/docs/server/reference/sql-statements/data-definition/create/create-index.md) statement. Without the INDEX privilege, user can still create indexes when creating a table using the [CREATE TABLE](/docs/server/server-usage/tables/create-table.md) statement if the user has have the CREATE privilege, and user can create indexes using the [ALTER TABLE](/docs/server/reference/sql-statements/data-definition/alter/alter-table.md) statement if they have the ALTER privilege. |
| Alter\_priv | enum('N','Y') | NO | | N | Can perform [ALTER TABLE](/docs/server/reference/sql-statements/data-definition/alter/alter-table.md) statements. |
| Create\_tmp\_table\_priv | enum('N','Y') | NO | | N | Can create temporary tables with the [CREATE TEMPORARY TABLE](/docs/server/server-usage/tables/create-table.md) statement. |
| Lock\_tables\_priv | enum('N','Y') | NO | | N | Acquire explicit locks using the [LOCK TABLES](/docs/server/reference/sql-statements/transactions/lock-tables.md) statement; user also needs to have the SELECT privilege on a table in order to lock it. |
| Create\_view\_priv | enum('N','Y') | NO | | N | Can create a view using the [CREATE\_VIEW](/docs/server/server-usage/views/create-view.md) statement. |
| Show\_view\_priv | enum('N','Y') | NO | | N | Can show the [CREATE VIEW](/docs/server/server-usage/views/create-view.md) statement to create a view using the [SHOW CREATE VIEW](/docs/server/reference/sql-statements/administrative-sql-statements/show/show-create-view.md) statement. |
| Create\_routine\_priv | enum('N','Y') | NO | | N | Can create stored programs using the [CREATE PROCEDURE](/docs/server/server-usage/stored-routines/stored-procedures/create-procedure.md) and [CREATE FUNCTION](/docs/server/reference/sql-statements/data-definition/create/create-function.md) statements. |
| Alter\_routine\_priv | enum('N','Y') | NO | | N | Can change the characteristics of a stored function using the [ALTER FUNCTION](/docs/server/reference/sql-statements/data-definition/alter/alter-function.md) statement. |
| Execute\_priv | enum('N','Y') | NO | | N | Can execute [stored procedure](/docs/server/server-usage/stored-routines/stored-procedures.md) or functions. |
| Event\_priv | enum('N','Y') | NO | | N | Create, drop and alter [events](/docs/server/server-usage/triggers-events/event-scheduler.md). |
| Trigger\_priv | enum('N','Y') | NO | | N | Can execute [triggers](/docs/server/server-usage/triggers-events/triggers.md) associated with tables the user updates, execute the [CREATE TRIGGER](/docs/server/server-usage/triggers-events/triggers/create-trigger.md) and [DROP TRIGGER](/docs/server/reference/sql-statements/data-definition/drop/drop-trigger.md) statements. |
| Delete\_history\_priv | enum('N','Y') | NO | | N | Can delete rows created through [system versioning](/docs/server/reference/sql-structure/temporal-tables/system-versioned-tables.md). |
The [Acl\_database\_grants](/docs/server/server-management/variables-and-modes/server-status-variables.md#acl_database_grants) status variable indicates how many rows the `mysql.db` table contains.
