特区彩票网MySQL视图表创建与修改

1、创建

CREATE [OR REPLACE] [<algorithm attributes>] VIEW [database.]< name> [(<columns>)]AS <select statement> [<check options>]例子:

CREATE VIEW `view_articles`ASSELECT a.id AS id, a.title AS title, a.content AS content, t.name AS tagname, u.firstname AS "username"FROM `articles` a LEFT JOIN `tags` t ON a.tag_id = t.id LEFT JOIN `users` u ON a.user_id = u.idORDER BY a.posttime DESC;修改

ALTER [<algorithm attributes>] VIEW [<database>.]< name> [(<columns>)]AS<select statement> [<check options>]例子:

ALTER VIEW `view_articles`ASSELECT a.id AS id, a.title AS title, a.content AS content, a.posttime AS posttime, t.name AS tagname, CONCAT(u.firstname,' ',u.lastname) AS "username"FROM `articles` a LEFT JOIN `tags` t ON a.tag_id = t.id LEFT JOIN `users` u ON a.user_id = u.idORDER BY a.posttime DESC;

修改已经建立好的视图表,最简单的方法就是在phpMyAdmin导出视图表的SQL,然后修改开头的“CREATE”(后面的”ALGORITHM=UNDEFINED DEFINER=`root`@`localhost` SQL SECURITY DEFINER”等不用管,保留它)为”ALTER”,运行语句即可。
