阿新 • • 發佈:2019-01-25
1、建立檢視
CREATE
VIEW `NewView`AS
SELECT
`user`.USER_ID,
`user`.USER_NAME,
department.DEPT_ID,
department.DEPT_NAME
FROM
`user` ,
department
WHERE
`user`.DEPT_ID = department.DEPT_ID ;
2、修改檢視
ALTER ALGORITHM=UNDEFINED DEFINER=`root`@`127.0.0.1` SQL SECURITY DEFINER VIEW `dept_user` AS select `user`.`USER_ID` AS `USER_ID`,`user`.`USER_NAME` AS `USER_NAME`,`department`.`DEPT_ID` AS `DEPT_ID`,`department`.`DEPT_NAME` AS `DEPT_NAME` from (`user` join `department`) where (`user`.`DEPT_ID` = `department`.`DEPT_ID`) ORDER BY department.DEPT_NO ASC ;
