Question

When did oracle start supporting "top":

select top ? p2_.PRODUCT_ID from PRODUCT?

Answer 1

I am not sure ORACLE ever had a TOP function. You want to use a TOP-N query.

For example:

select  *
  from  (SELECT  *
           FROM  foo
          where  foo_id=[number]
       order by  foo_id desc)
 where  rownum <= 3   

This will get you the top three results (because I order by desc in the sub query)
