要创建MySQL视图,请按以下语法使用CREATE VIEW-
create view yourViewName as select * from yourTableName;
让我们首先创建一个表-
mysql> create table DemoTable1802 ( StudentId int, StudentName varchar(20) );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1802 values(101,'John'); mysql> insert into DemoTable1802 values(102,'Carol'); mysql> insert into DemoTable1802 values(103,'Sam');
使用select语句显示表中的所有记录-
mysql> select * from DemoTable1802;
这将产生以下输出-
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 101 | John | | 102 | Carol | | 103 | Sam | +-----------+-------------+ 3 rows in set (0.00 sec)
这是创建视图的查询-
mysql> create view view_DemoTable1802 as select * from DemoTable1802;
使用select语句显示视图中的所有记录-
mysql> select * from view_DemoTable1802;
这将产生以下输出-
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 101 | John | | 102 | Carol | | 103 | Sam | +-----------+-------------+ 3 rows in set (0.00 sec)
