MySQL INSERT INTO SELECT到具有AUTO_INCREMENT的表中
让我们创建一个表-
mysql> create table DemoTable1923 ( UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY, UserName varchar(20) );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1923(UserId,UserName)
select 101 as UserId,'Chris' as UserName;
Records: 1 Duplicates: 0 Warnings: 0
mysql> insert into DemoTable1923(UserId,UserName)
select 102 as UserId,'Robert' as UserName;
Records: 1 Duplicates: 0 Warnings: 0
mysql> insert into DemoTable1923(UserId,UserName)
select 103 as UserId,'Sam' as UserName;
Records: 1 Duplicates: 0 Warnings: 0使用select语句显示表中的所有记录-
mysql> select * from DemoTable1923;
这将产生以下输出-
+--------+----------+ | UserId | UserName | +--------+----------+ | 101 | Chris | | 102 | Robert | | 103 | Sam | +--------+----------+ 3 rows in set (0.00 sec)
