MySQL left padding with zeros separated by hyphen?
Let us first create a table −
mysql> create table DemoTable829(SerialNumber int); Query OK, 0 rows affected (0.64 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable829 values(100); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable829 values(101); Query OK, 1 row affected (0.26 sec) mysql> insert into DemoTable829 values(102); Query OK, 1 row affected (0.08 sec) mysql> insert into DemoTable829 values(103); Query OK, 1 row affected (0.09 sec) mysql> insert into DemoTable829 values(104); Query OK, 1 row affected (0.60 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable829;
This will produce the following output −
+--------------+ | SerialNumber | +--------------+ | 100 | | 101 | | 102 | | 103 | | 104 | +--------------+ 5 rows in set (0.00 sec)
Following is the query to pad zeros separated by a hyphen −
mysql> select RIGHT(CONCAT('000-', SerialNumber), 7) from DemoTable829;This will produce the following output −
+----------------------------------------+
| RIGHT(CONCAT('000-', SerialNumber), 7) |
+----------------------------------------+
| 000-100 |
| 000-101 |
| 000-102 |
| 000-103 |
| 000-104 |
+----------------------------------------+
5 rows in set (0.00 sec)
