For this, you can use the ORDER BY CASE statement. Let us first create a table −
mysql> create table DemoTable order by with vas Color varchar(100) ); Query OK, 0 rows affected (0.64 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Red'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable values('Green'); Query OK, 1 row affected (0.10 sec) mysql> insert into DemoTable values('Blue'); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable values('Yellow'); Query OK, 1 row affected (0.18 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+--------+ | Color | +--------+ | Red | | Green | | Blue | | Yellow | +--------+ 4 rows in set (0.00 sec)
Here is the query to order by with CASE WHEN −
mysql> select *from DemoTable order by case Color when 'Blue' then 10 when 'Green' then 20 when 'Yellow' then 30 else 100 end ;
This will produce the following output −
+--------+ | Color | +--------+ | Blue | | Green | | Yellow | | Red | +--------+ 4 rows in set (0.00 sec)
