DROP USER user [, user] ...

The DROP USER statement removes one or more MySQL accounts and their privileges. It removes privilege rows for the account from all grant tables. An error occurs for accounts that do not exist. To use this statement, you must have the global CREATE USER privilege or the DELETE privilege for the mysql database.

Each account name uses the format described in Section 6.2.3, “Specifying Account Names”. For example:

DROP USER 'jeffrey'@'localhost';

If you specify only the user name part of the account name, a host name part of '%' is used.

DROP USER does not automatically drop or invalidate databases or objects within them that the old user created. This includes stored programs or views for which the DEFINER attribute names the dropped user. Attempts to access such objects may produce an error if they execute in definer security context. (For information about security context, see Section 20.6, “Access Control for Stored Programs and Views”.)
