Add leading zeros to a MySQL column?
To add leading zeros, you can use LPAD(). Let us first create a table −
mysql> create table DemoTable ( Code varchar(100) ); Query OK, 0 rows affected (0.87 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('JS');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('CB');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values('DM');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('CT');
Query OK, 1 row affected (0.07 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+------+ | Code | +------+ | JS | | CB | | DM | | CT | +------+ 4 rows in set (0.00 sec)
Now, let us add leading zeros in MySQL −
mysql> update DemoTable set Code=LPAD(Code, 8, '0'); Query OK, 4 rows affected (0.10 sec) Rows matched: 4 Changed: 4 Warnings: 0
Let us check the table records once again −
mysql> select *from DemoTable;
This will produce the following output −
+----------+ | Code | +----------+ | 000000JS | | 000000CB | | 000000DM | | 000000CT | +----------+ 4 rows in set (0.00 sec)
