Implement Custom Sort Order in MySQL
To implement custom sort order in MySQL, you need to use ORDER BY FIELD(). Let us first create a table −
mysql> create table DemoTable -> ( -> Designation varchar(100) -> ); Query OK, 0 rows affected (1.65 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Software Engineer');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values('Associate Software Engineer');
Query OK, 1 row affected (0.25 sec)
mysql> insert into DemoTable values('Software Development Engineer');
Query OK, 1 row affected (0.19 sec)
mysql> insert into DemoTable values('Product Manager');
Query OK, 1 row affected (0.17 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+-------------------------------+ | Designation | +-------------------------------+ | Software Engineer | | Associate Software Engineer | | Software Development Engineer | | Product Manager | +-------------------------------+ 4 rows in set (0.00 sec)
Following is the query to implement custom sort order in MySQL −
mysql> select *from DemoTable -> order by field(Designation,'Associate Software Engineer','Software Engineer','Software Development Engineer','Product Manager');
This will produce the following output −
+-------------------------------+ | Designation | +-------------------------------+ | Associate Software Engineer | | Software Engineer | | Software Development Engineer | | Product Manager | +-------------------------------+ 4 rows in set (0.02 sec)
