Following is the error and it occurs when you implement ZEROFILL incorrectly−
mysql> create table DemoTable -> ( -> StudentCode int(10) NOT NULL ZEROFILL AUTO_INCREMENT PRIMARY KEY -> ); ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ZEROFILL AUTO_INCREMENT PRIMARY KEY )' at line 3
For correct implementation, use the below syntax −
Syntax
yourColumnName int(10) ZEROFILL NOT NULL AUTO_INCREMENT PRIMARY KEY
Let us first create a table −
mysql> create table DemoTable -> ( -> StudentCode int(10) ZEROFILL NOT NULL AUTO_INCREMENT PRIMARY KEY -> ); Query OK, 0 rows affected (0.55 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values(); Query OK, 1 row affected (0.21 sec) mysql> insert into DemoTable values(); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable values(); Query OK, 1 row affected (0.28 sec) mysql> insert into DemoTable values(); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values(); Query OK, 1 row affected (0.10 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------------+ | StudentCode | +-------------+ | 0000000001 | | 0000000002 | | 0000000003 | | 0000000004 | | 0000000005 | +-------------+ 5 rows in set (0.00 sec)
