Perform custom sorting in MySQL

To perform custom sorting in MySQL, use ORDER BY FIELD(). Let us first create a table −

mysql> create table DemoTable    -> (    -> Id int    -> ); Query OK, 0 rows affected (0.82 sec)

Insert some records in the table using insert command:

mysql> insert into DemoTable values(101); Query OK, 1 row affected (0.23 sec) mysql> insert into DemoTable values(103); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable values(102); Query OK, 1 row affected (0.08 sec) mysql> insert into DemoTable values(105); Query OK, 1 row affected (0.14 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

This will produce the following output −

+------+ |  Id  | +------+ |  101 | |  103 | |  102 | |  105 | +------+ 4 rows in set (0.00 sec)

Here is the query to perform custom sorting −

mysql> select *from DemoTable order by field(Id,102,105,101,103);

This will produce the following output −

+------+ | Id   | +------+ |  102 | |  105 | |  101 | |  103 | +------+ 4 rows in set (0.00 sec)
