Hi to everyone,

Compliments for the website very useful and powerful
I have a question, I hope someone can help me, I'll try to be as much clear as I can.

I need to use clausole GROUP BY one thing that I know when I use it I have to select the same column.
So is it possible to say ok for the aggregate rows I want select a custom value I mean a constant 'MORE'.
I try to explain in another way to be much clear

I have this table

A B C D
_ _ _ ___
1 2 3 ita
1 2 3 fra
1 2 3 eng
4 4 4 fra

I want obtain this

A B C D
_ _ _ ___
1 2 3 MORE
4 4 4 fra

But in the follow method doesn't work because all rows will have 'MORE'

select A, B, C, 'MORE' as D from Table
where ...
GROUP BY A, B, C, D

Please can you suggest me something I still looking for help, I tried to serch in your forum and on google as well but nothing.

Thank you very much in advance.

Francesco
