MySQL ORDER BY 'ENUM' type value based on conditions
For this, use ORDER BY CASE statement. Let us first create a table, wherein we have ENUM type column −
mysql> create table DemoTable1461
-> (
-> DeckOfCards ENUM('K','J','A','Q')
-> );
Query OK, 0 rows affected (0.64 sec)Insert some records in the table using insert command −
mysql> insert into DemoTable1461 values('K');
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable1461 values('A');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable1461 values('J');
Query OK, 1 row affected (0.44 sec)
mysql> insert into DemoTable1461 values('Q');
Query OK, 1 row affected (0.13 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1461;
This will produce the following output −
+-------------+
| DeckOfCards |
+-------------+
| K |
| A |
| J |
| Q |
+-------------+
4 rows in set (0.00 sec)
Following is the query to order by ENUM type value −
mysql> select * from DemoTable1461
-> order by
-> case DeckOfCards when 'A' then 100
-> when 'K' then 101
-> when 'Q' then 102
-> else 103
-> end;
This will produce the following output −
+-------------+
| DeckOfCards |
+-------------+
| A |
| K |
| Q |
| J |
+-------------+
4 rows in set (0.00 sec)
