如何在WHERE子句中使用MySQL VIEW？
对于带有WHERE子句的MySQLVIEW，语法如下-
select * from yourViewName where yourColumnName='yourValue';
让我们首先创建一个-
mysql> create table DemoTable1432 -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(20), -> StudentBranchName varchar(20) -> );
使用insert在表中插入一些记录-
mysql> insert into DemoTable1432(StudentName,StudentBranchName) values('Chris','CS');
mysql> insert into DemoTable1432(StudentName,StudentBranchName) values('David','CE');
mysql> insert into DemoTable1432(StudentName,StudentBranchName) values('Mike','ME');使用选择显示表中的所有记录-
mysql> select * from DemoTable1432;
这将产生以下输出-
+-----------+-------------+-------------------+ | StudentId | StudentName | StudentBranchName | +-----------+-------------+-------------------+ | 1 | Chris | CS | | 2 | David | CE | | 3 | Mike | ME | +-----------+-------------+-------------------+ 3 rows in set (0.00 sec)
以下是创建视图的查询-
mysql> create view DemoTable1432_View as select * from DemoTable1432;
以下是将MySQL视图与where子句一起使用的查询-
mysql> select * from DemoTable1432_View where StudentBranchName='CS';
这将产生以下输出-
+-----------+-------------+-------------------+ | StudentId | StudentName | StudentBranchName | +-----------+-------------+-------------------+ | 1 | Chris | CS | +-----------+-------------+-------------------+ 1 row in set (0.03 sec)
