먼저 호스트 이름과 함께 모든 사용자 이름을 표시하겠습니다 -
mysql> select user,host from MySQL.user;
이것은 다음과 같은 출력을 생성합니다 -
+------------------+-----------+ | user | host | +------------------+-----------+ | Bob | % | | Charlie | % | | Robert | % | | User2 | % | | mysql.infoschema | % | | mysql.session | % | | mysql.sys | % | | root | % | | @UserName@ | localhost | | Adam | localhost | | Adam Smith | localhost | | Chris | localhost | | David | localhost | | James | localhost | | John | localhost | | John Doe | localhost | | Michael | localhost | | Mike | localhost | | User1 | localhost | | am | localhost | | hbstudent | localhost | | mysql.infoschema | localhost | | mysql.session | localhost | +------------------+-----------+ 23 rows in set (0.00 sec)
다음은 특정 사용자의 모든 권한을 조회하는 쿼리입니다. -
mysql> show grants for 'John'@'localhost';
이것은 다음과 같은 출력을 생성합니다 -
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Grants for John@localhost | +----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | 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`@`localhost` | | GRANT BACKUP_ADMIN,BINLOG_ADMIN,CONNECTION_ADMIN,ENCRYPTION_KEY_ADMIN,GROUP_REPLICATION_ADMIN,PERSIST_RO_VARIABLES_ADMIN,REPLICATION_SLAVE_ADMIN,RESOURCE_GROUP_ADMIN,RESOURCE_GROUP_USER,ROLE_ADMIN,SET_USER_ID,SYSTEM_VARIABLES_ADMIN,XA_RECOVER_ADMIN ON *.* TO `John`@`localhost` | +----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 2 rows in set (0.07 sec)
