MySQL query to set my auto increment column ( id ) to zero or reset the value of auto increment field?
Use ALTER table to set the auto_increment column to 0 or reset with another value
ALTER TABLE yourTableName AUTO_INCREMENT=0;
The above syntax will begin from 1.
Let us first create a table −
mysql> create table DemoTable698 ( ClientId int NOT NULL AUTO_INCREMENT PRIMARY KEY ) auto_increment=109; Query OK, 0 rows affected (0.88 sec)
Here is the query to reset the auto_increment value to 0 −
mysql> alter table DemoTable698 AUTO_INCREMENT=0; Query OK, 0 rows affected (0.21 sec) Records: 0 Duplicates: 0 Warnings: 0
Insert some records in the table using insert command. Here, we haven’t inserted anything since we want to display auto increment value after setting it from beginning again −
mysql> insert into DemoTable698 values(); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable698 values(); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable698 values(); Query OK, 1 row affected (0.12 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable698;
This will produce the following output -
+----------+ | ClientId | +----------+ | 1 | | 2 | | 3 | +----------+ 3 rows in set (0.00 sec)
