Set MySQL int column to auto increment by 1 beginning at 10000?

Let us first create a table. Here, we have set UserId as AUTO_INCREMENT PRIMARY KEY −

mysql> create table DemoTable
(
   UserId int NOT NULL AUTO_INCREMENT PRIMARY KEY
);
Query OK, 0 rows affected (0.72 sec)

Following is the query to set int column to auto increment by 1 beginning at 10000 −

mysql> alter table DemoTable AUTO_INCREMENT=10000;
Query OK, 0 rows affected (0.31 sec)
Records: 0 Duplicates: 0 Warnings: 0

Insert records in the table using insert command −

mysql> insert into DemoTable values();
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable values();
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values();
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values();
Query OK, 1 row affected (0.08 sec)

Display records from the table using select command −

mysql> select *from DemoTable;

This will produce the following output −

+--------+
| UserId |
+--------+
| 10000  |
| 10001  |
| 10002  |
| 10003  |
+--------+
4 rows in set (0.00 sec)
