显示 MySQL 中 VIEW 的内容?
mysqlmysqli database
以下是语法 −
select * from yourViewName;
首先我们创建一个表 −
mysql> create table DemoTable1388 -> ( -> StudentId int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> StudentName varchar(40) -> ); Query OK, 0 rows affected (0.71 sec)
使用 insert 命令在表中插入一些记录 −
mysql> insert into DemoTable1388(StudentName) values('Chris');
Query OK, 1 row affected (0.23 sec)
mysql> insert into DemoTable1388(StudentName) values('Bob');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable1388(StudentName) values('David');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1388(StudentName) values('Mike');
Query OK, 1 row affected (0.29 sec)
使用 select 语句显示表中的所有记录 −
mysql> select * from DemoTable1388;
这将产生以下输出 −
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 1 | Chris | | 2 | Bob | | 3 | David | | 4 | Mike | +-----------+-------------+ 4 rows in set (0.00 sec)
以下是在 MySQL 中创建视图的查询 −
mysql> create view view1388 as select *from DemoTable1388 where StudentId=3; Query OK, 0 rows affected (0.13 sec)
现在，在 MySQL 中显示视图的内容 −
mysql> select * from view1388;
这将产生以下输出 −
+-----------+-------------+ | StudentId | StudentName | +-----------+-------------+ | 3 | David | +-----------+-------------+ 1 row in set (0.19 sec)
