在MySQL中显示用户的所有授予
使用INFORMATION_SCHEMA.SCHEMA_PRIVILEGES显示用户的所有补助-
select *from INFORMATION_SCHEMA.SCHEMA_PRIVILEGES;
让我们实现以上语法以显示用户的所有授权-
mysql> select *from INFORMATION_SCHEMA.SCHEMA_PRIVILEGES;
这将产生以下输出-
+-----------------------------+---------------+--------------------+-------------------------+--------------+| GRANTEE | TABLE_CATALOG | TABLE_SCHEMA | PRIVILEGE_TYPE | IS_GRANTABLE |
