Custom sorting using two different columns in MySQL?
For this, use ORDER BY clause along with CASE statement. Let us first create a table −
mysql> create table DemoTable1610 -> ( -> Marks int, -> Name varchar(20) -> ) ; Query OK, 0 rows affected (0.51 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1610 values(85,'John'); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable1610 values(78,'Carol'); Query OK, 1 row affected (0.11 sec) mysql> insert into DemoTable1610 values(78,'John'); Query OK, 1 row affected (0.22 sec) mysql> insert into DemoTable1610 values(85,'Carol'); Query OK, 1 row affected (0.20 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1610;
This will produce the following output
+-------+-------+ | Marks | Name | +-------+-------+ | 85 | John | | 78 | Carol | | 78 | John | | 85 | Carol | +-------+-------+ 4 rows in set (0.00 sec)
Here is the query to custom sort using two different columns in MySQL −
mysql> select * from DemoTable1610 -> order by Marks,case when Name='Carol' then 1 else 0 end;
This will produce the following output
+-------+-------+ | Marks | Name | +-------+-------+ | 78 | John | | 78 | Carol | | 85 | John | | 85 | Carol | +-------+-------+ 4 rows in set (0.00 sec)
