MySql视图view的使用：创建、修改、删除

一、MySql创建视图

CREATE VIEW 视图名 AS SELECT 查询语句;

注：将 SELECT 查询语句 替换成所写的sql语句

eg:

CREATE VIEW v_article AS SELECT A.title, A.content, A.author, C.name AS categoryName FROM article AS A JOIN articleCategory AS C ON A.articleCategoryId=C.articleCategoryId;

二、MySql视图修改

ALTER VIEW 视图名 AS SELECT 查询语句;

注：同上

三、MySql视图删除

DROP VIEW 视图名;

eg:

DROP VIEW v_article;
