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)
