How to order 1,2,3 not 1, 10, 11, 12 in mySQL

Question

The following code outputs in order of 1, 10, 11, 12 of id.

I want to make it 1,2,3,4...

Could anyone tell me what I should do please.

$Q = $         


        

Answer 1

You can do an explicit cast by doing:

ORDER BY CAST(category_id AS UNSIGNED INTEGER)

But you should reconsider you database layout as a field containing only numeric values should also be of an numeric type..
