I am realy lucky: I am having a hard time getting the wright answer from a query that is very complicated, trying to manipulate the data with group by, with, subqueries, etc. and maybe my answer to it would be the over(partition) case that, yesterday, I did not know the existence ...

I'll have to work on it more, but at least I understand better...

Thanks Hugo

Thanks da-zero

... and ya, thanks to UK and US for the good laughs:-D
