Question

I want to get those Product in ascending order who number is greater in mysql

  order_id    |     product_id    
     1        |         13    
     1        |         12    
     1        |         24    
     2        |         14    
     2        |         245    
     2        |         23    
     3        |         14    
     3        |         23    
     4        |         14    

i have done that code but its not working

SELECT  product_id  FROM `sales_order_item`  ORDER BY COUNT('product_id') ASC

i want priduct_id in ascending order on the basis of there count\\

product_id
    14
    23
    13
    24
    245

as 14 occurs 4 times it must have to be on top and so on

Answer 1

use order by COUNT('product_id') desc

SELECT  product_id,COUNT('product_id') as cnt  FROM `sales_order_item` 
group by product_id 
ORDER BY cnt desc
