My query below is probably flawed... I just remembered you would have to alias rownum...
select inner_row as rownum, gender from (select rownum as inner_row, gender from emp2 where rownum <= 600) where rownum >= 500; Regards, Mark. Ryan did a good job of explaining the use of rownum - better than my attempt. Mark Richard To: [EMAIL PROTECTED] 09/07/2003 11:37 cc: Subject: Re: something appears to be funny with ROWNUM(Document link: Mark Richard) ROWNUM has to start from 1 - If you never select a row then rownum can't increase. You have to assign rownums and then filter them out later, usually using a subquery. The solution to your specific query below would be something like: select rownum, gender from (select rownum, gender from emp2 where rownum <= 600 ) where rownum >= 500; The emails I sent earlier for your other problem are based around the fact that rownum will restart from 1 during each iteration. You possibly don't understand rownum properly - it is a unique number assigned to a specific result set, not the rows existing in the underlying table. It must start from 1 each time and therefore where clauses can only test some conditions like "rownum = 1" (get a single row), "rownum <= x" (get up to x rows).

SELECT Rownum, Gender FROM EMP2 WHERE ROWNUM <= 600; ------------ 2. this one right here told me no rows selected... SELECT Rownum, Gender FROM EMP2 WHERE ROWNUM BETWEEN 500 and 600; I dont get it... something is funny with ROWNUM... Any ideas? thx maa __________________________________ Do you Yahoo!? SBC Yahoo!
