MySQL INSERT INTO SELECT into a table with AUTO_INCREMENT
Let us create a table −
mysql> create table DemoTable1923 ( UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY, UserName varchar(20) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1923(UserId,UserName) select 101 as UserId,'Chris' as UserName; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql> insert into DemoTable1923(UserId,UserName) select 102 as UserId,'Robert' as UserName; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0 mysql> insert into DemoTable1923(UserId,UserName) select 103 as UserId,'Sam' as UserName; Query OK, 1 row affected (0.00 sec) Records: 1 Duplicates: 0 Warnings: 0
Display all records from the table using select statement −
mysql> select * from DemoTable1923;
This will produce the following output −
+--------+----------+ | UserId | UserName | +--------+----------+ | 101 | Chris | | 102 | Robert | | 103 | Sam | +--------+----------+ 3 rows in set (0.00 sec)
