MySQL query to add 0's to numbers with less than 9 digits?
Use LPAD() to add 0's to numbers with less than 9 digits. Let us first create a table −
mysql> create table DemoTable ( Value varchar(20) ); Query OK, 0 rows affected (0.55 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('3646465');
Query OK, 1 row affected (0.29 sec)
mysql> insert into DemoTable values('9485757591');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('485756');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable values('959585');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values('124');
Query OK, 1 row affected (0.27 sec)Following is the query to display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+------------+ | Value | +------------+ | 3646465 | | 9485757591 | | 485756 | | 959585 | | 124 | +------------+ 5 rows in set (0.00 sec)
Following is the query to add 0's to numbers with less than 9 digits −
mysql> select lpad(Value,9,'0') from DemoTable;
This will produce the following output −
+-------------------+ | lpad(Value,9,'0') | +-------------------+ | 003646465 | | 948575759 | | 000485756 | | 000959585 | | 000000124 | +-------------------+ 5 rows in set (0.03 sec)
