Sorting max to min value in MySQL

To sort from max to min value, use ORDER BY length(). Let us first create a table −

mysql> create table DemoTable
   -> (
   -> Price varchar(20)
   -> );
Query OK, 0 rows affected (0.92 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('80');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable values('800');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable values('108');
Query OK, 1 row affected (0.50 sec)
mysql> insert into DemoTable values('765');
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 −

+-------+
| Price |
+-------+
| 80    |
| 800   |
| 108   |
| 765   |
+-------+
4 rows in set (0.00 sec)

Here is the query to sort max to min value in MySQL −

mysql> select *from DemoTable
   -> order by length(Price) DESC,Price DESC;

This will produce the following output −

+-------+
| Price |
+-------+
| 800   |
| 765   |
| 108   |
| 80    |
+-------+
4 rows in set (0.00 sec)
