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)
