以下是语法-

show create view yourViewName;

让我们首先创建一个表-

create table DemoTable
-> (
-> StudentName varchar(20)
-> );

使用插入命令在表中插入一些记录-

insert into DemoTable values('Chris');

insert into DemoTable values('Robert');

insert into DemoTable values('David');

使用select语句显示表中的所有记录-

select *from DemoTable;

输出结果

这将产生以下输出-

+-------------+
| StudentName |
+-------------+
| Chris       |
| Robert      |
| David       |
+-------------+
3 rows in set (0.00 sec)

以下是为表创建视图的查询-

CREATE VIEW view_DemoTable AS SELECT StudentName from DemoTable;

以下是查询以查看组成MySQL视图的查询-

show create view view_DemoTable;

输出结果

这将产生以下输出-

+-------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+
| View              | Create View | character_set_client | collation_connection |
+-------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+
| view_DemoTable     | CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`%` SQL
SECURITY DEFINER VIEW `view_DemoTable` AS select `DemoTable`.`StudentName` AS
`StudentName` from `DemoTable` | utf8 | utf8_general_ci |
+-------------------+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------------------+----------------------+
1 row in set (0.00 sec)

让我们检查查看记录-

select *from view_DemoTable;

输出结果

这将产生以下输出-

+-------------+
| StudentName |
+-------------+
| Chris       |
| Robert      |
| David       |
+-------------+
3 rows in set (0.05 sec)
