Subject Re: [firebird-support] Why won't Group By work?
Author Rodrigo Gonçalves
To group either your fields not in the group by clause are calculated (sum,
count, etc...) or you put them in the group by clause.

By the way, why would you group a select where you take an id (which I
suppose is unique to each row)?

Rodrigo
