怎么查看视图结构mysql_MySQL 中如何查看组成视图的内容
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)
