Syntax

DROP USER user_name [, user_name] ...
MariaDB starting with 10.1.3

In MariaDB 10.1.3, the DROP USER syntax was updated to:

DROP USER [IF EXISTS] user_name [, user_name] ...

Description

The DROP USER statement removes one or more MariaDB accounts. It removes privilege rows for the account from all grant tables. To use this statement, you must have the global CREATE USER privilege or the DELETE privilege for the mysql database. Each account is named using the same format as for the CREATE USER statement; for example, 'jeffrey'@'localhost'. If you specify only the user name part of the account name, a host name part of '%' is used. For additional information about specifying account names, see CREATE USER.

Note that, if you specify an account that is currently connected, it will not be deleted until the connection is closed. The connection will not be automatically closed.

If any of the specified user accounts do not exist, ERROR 1396 (HY000) results. If an error occurs, DROP USER will still drop the accounts that do not result in an error. Only one error is produced for all users which have not been dropped:

ERROR 1396 (HY000): Operation DROP USER failed for 'u1'@'%','u2'@'%'

Failed CREATE or DROP operations, for both users and roles, produce the same error code.

Examples

DROP USER bob;
MariaDB starting with 10.1.3

The same thing using the optional IF EXISTS clause:

DROP USER IF EXISTS bob;
