In this case, the rownum should not be a problem when using it in a sub
select? You are only trying to get the first seven rows from the sub
select.. Whats the problem?
Fair enough, using a rownum on a single select may not be reliable, but in
this case it should work like a charm..

No, No not for this statement , my group leader tells that rownum is not
used so much in applications becouse it can give wrong results sometimes. I
do not know if it is correct . I ask you for approve him or not..
Thanks
