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)
