MySQL query to convert a single digit number to two-digit
For this, you can use LPAD() and pad a value on the left.
Let us first create a table −
mysql> create table DemoTable767 (Value varchar(100)); Query OK, 0 rows affected (1.40 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable767 values('4');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable767 values('5');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable767 values('6');
Query OK, 1 row affected (0.39 sec)
mysql> insert into DemoTable767 values('1');
Query OK, 1 row affected (0.10 sec)Display all records from the table using select statement −
mysql> select *from DemoTable767;
This will produce the following output -
+-------+ | Value | +-------+ | 4 | | 5 | | 6 | | 1 | +-------+ 4 rows in set (0.00 sec)
Following is the query to convert a single digit number to two-digit by padding values −
mysql> select lpad(Value,2,'0') from DemoTable767;
This will produce the following output -
+-------------------+ | lpad(Value,2,'0') | +-------------------+ | 04 | | 05 | | 06 | | 01 | +-------------------+ 4 rows in set (0.00 sec)
