We try to make MySQL Server follow the ANSI SQL standard and the ODBC SQL standard, but MySQL Server performs operations differently in some cases:
There are several differences between the MySQL and standard SQL privilege systems. For example, in MySQL, privileges for a table are not automatically revoked when you delete a table. You must explicitly issue a
REVOKEstatement to revoke privileges for a table. For more information, see Section 18.104.22.168, “REVOKE Syntax”.
