Re: rownum

hi,

i think i don't understand what you want.... but from what i can figure out ur problem seems for example
Select sales_amt from sales;
now u want to display the top 10 records

if that's the case u could try
Select sales_amt from sales where rownum <= 10 order by sales_amt;

however this is not the most effective method in terms of performance... u should as far as possible use sub-query to get the result...

lemme know if this is ur basic query n then we'll work it out...

regards.
