13.5.1.5. REVOKE Syntax

REVOKE priv_type [(column_list)] [, priv_type [(column_list)]] ...
    ON [object_type] {tbl_name | * | *.* | db_name.*}
    FROM user [, user] ...

REVOKE ALL PRIVILEGES, GRANT OPTION FROM user [, user] ...

The REVOKE statement enables system administrators to revoke privileges from MySQL accounts. To use REVOKE, you must have the GRANT OPTION privilege, and you must have the privileges that you are revoking.

For details on the levels at which privileges exist, the allowable priv_type values, and the syntax for specifying users and passwords, see Section 13.5.1.3, “GRANT Syntax”

If the grant tables hold privilege rows that contain mixed-case database or table names and the lower_case_table_names system variable is set to a non-zero value, REVOKE cannot be used to revoke these privileges. It will be necessary to manipulate the grant tables directly. (GRANT will not create such rows when lower_case_table_names is set, but such rows might have been created prior to setting the variable.)

To revoke all privileges, use the following syntax, which drops all global, database-, table-, and column-level privileges for the named user or users:

REVOKE ALL PRIVILEGES, GRANT OPTION FROM user [, user] ...

To use this REVOKE syntax, you must have the global CREATE USER privilege or the UPDATE privilege for the mysql database.
