MySQL 如何从视图创建表

要从下面的视图创建表，需使用以下语法−

create table yourTableName select *from yourViewName;

让我们先创建一个表−

mysql> create table DemoTable830(Name varchar(100));
Query OK, 0 rows affected (0.91 sec)

使用插入命令将一些记录插入到表中−

mysql> insert into DemoTable830 values('Chris');
Query OK, 1 row affected (0.41 sec)
mysql> insert into DemoTable830 values('Robert');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable830 values('David');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable830 values('Mike');
Query OK, 1 row affected (0.16 sec)

使用select语句显示表中的所有记录−

mysql> select *from DemoTable830;

这将产生如下输出−

+--------+
| Name   |
+--------+
| Chris  |
| Robert |
| David  |
| Mike   |
+--------+
4 rows in set (0.00 sec)

以下是创建视图的查询−

mysql> create view table_view AS select *from DemoTable830;
Query OK, 0 rows affected (0.39 sec)

现在，我们将从视图创建一个表。以下是查询−

mysql> create table DemoTable831 select *from table_view;
Query OK, 4 rows affected (1.64 sec)
Records: 4 Duplicates: 0 Warnings: 0

检查已从视图创建的表的记录−

mysql> select *from DemoTable831;

这将产生如下输出−

+--------+
| Name   |
+--------+
| Chris  |
| Robert |
| David  |
| Mike   |
+--------+
4 rows in set (0.00 sec)
