Question

I am using simple order by clause to show products according to available quantity

Below is the query I am using:

SELECT * FROM productsinfo ORDER BY quantity desc  

Query giving no error but sorting order is not correct.Anyone please tell me where I am wrong.

EDIT

Have checked my quentity clumn is varchar type.I am storing values in 1,215 10,456 format.

Answer 1

Might be your quantity column is varchar type so it’s not sorting as numbers.Please check.
You need to cast it in integer type

Try below:

SELECT * FROM productsinfo ORDER BY CAST(quantity AS UNSIGNED ) desc 

OR Use below trick.

SELECT * FROM productsinfo ORDER BY quantity+0 DESC
