Try this:
select * from your_table
where rownum<=n;
rownum is a preudo column which numbers the rows of the resulting data set. So You can't do the following:
select * from your_table
where rownum=15;
This gives no result because every row selected get rownum=1 which is <>15. So the row isn't selected an the next row checked again gets rownum=1...
