I wonder that query "select * from tab group by id rownum<=500" which contains more than 500 records show only 117 records. I think it's because of "GROUP BY" statement. How I can limit to exact 500 records my output? Please help.

Rownum would work properly when you dont use = operator in the query. Try the same with ROWNUM<501 then it should give your desired result, I guess. As per my experience, the ROWNUM does not work properly when it is given with = or BETWEEN operator.
Try it out. Hope it works for you.
