MySQL表複製
MySQL Server doesn't support the SELECT ... INTO TABLE Sybase SQL extension. Instead, MySQL Serversupports the INSERT INTO ... SELECT standard SQLsyntax, which is basically the same thing. //官方文檔說明
MySQL是不支持SELECT … INTO語法的,使用INSERT INTO … SELECT替代相同用法,以下是兩種表複製方法
1、 表不存在複製
- [sql] view plaincopyprint?
- mysql>show tables;
- +-----------------+
- |Tables_in_test1 |
- +-----------------+
- |cpu_stat |
- |test1 |
- |test2 |
- |test3 |
- +-----------------+
- 4rows in set (0.02 sec)
- mysql> create tabletest4 as select * from test1 where 1=0;
- //僅複製表結構
- QueryOK, 0 rows affected (0.06 sec)
- Records:0 Duplicates: 0 Warnings: 0
- mysql> create tabletest5 as select * from test1;
- //把表test1所有內容複製爲test5
- QueryOK, 7 rows affected (0.11 sec)
- Records:7 Duplicates: 0 Warnings: 0
- mysql>
2、 表已經存在複製
- [sql] view plaincopyprint?
- mysql> create table test6(id int not null auto_increment primary key, name varchar(20));
- Query OK, 0 rows affected (0.13 sec)
- mysql> insert into test6(name) select name from test1;
- //只複製name列
- Query OK, 7 rows affected (0.06 sec)
- Records: 7 Duplicates: 0 Warnings: 0
- mysql> select * from test6;
- +----+-------+
- | id | name |
- +----+-------+
- | 1 | wu |
- | 2 | terry |
- | 3 | tang |
- ……
- 7 rows in set (0.00 sec)
- mysql>
