where clause help, please

hi all,
i want to get the top 3 product that are the most sold, i want to use in the where clause, rowNum <= 3 but i dont know what is the exact syntax, my attempt is this:

select Prod_Code , sum(qty) from purch
group by Prod_Code
order by sum(qty) desc

and from this i want just the first 3, rowNum will do the thing in where but would you please tell me how to imply it properly?

thanks. Received on Wed Jan 02 2008 - 17:12:07 CST
