检查MySQL中特定用户的特权（授予）？
如果要检查特定用户的特权，请使用以下语法-
SHOW GRANTS FOR 'yourUserName'@'yourHostName';
上面的语法将检查特定用户的特权。
要检查特定用户的特权，请使用FOR。假设我们有一个用户名“JOHN”，主机是“％”。以下是获取用户“JOHN”特权的查询-
mysql> SHOW GRANTS FOR 'JOHN'@'%';
这将产生以下输出-
+--------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------- --------------+ | Grants for JOHN@% | +--------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------- --------------+ | GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, SUPER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE, CREATE ROLE, DROP ROLE ON *.* TO `JOHN`@`%` WITH GRANT OPTION | | GRANT BACKUP_ADMIN,BINLOG_ADMIN,CONNECTION_ADMIN,ENCRYPTION_KEY_ADMIN,GR OUP_REPLICATION_ADMIN,PERSIST_RO_VARIABLES_ADMIN,REPLICATION_SLAVE_A DMIN,RESOURCE_GROUP_ADMIN,RESOURCE_GROUP_USER,ROLE_ADMIN,SET_USE R_ID,SYSTEM_VARIABLES_ADMIN,XA_RECOVER_ADMIN ON *.* TO `JOHN`@`%` WITH GRANT OPTION | +--------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------- ---------------------------------------------------------------------------------------------------------------------------- --------------+ 2 rows in set (0.00 sec)
