Set custom Auto Increment with ZEROFILL in MySQL
Let us first create a table. Here. We have set UserId column with ZEROFILL and AUTO_INCREMENT
mysql> create table DemoTable1831 ( UserId int(7) zerofill auto_increment, PRIMARY KEY(UserId) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1831 values(101); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1831 values(); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1831 values(); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1831 values(); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1831;
This will produce the following output. All the values have zerofill for UserId field width 7
+---------+ | UserId | +---------+ | 0000101 | | 0000102 | | 0000103 | | 0000104 | +---------+ 4 rows in set (0.00 sec)
