Hi,
Is it something like row_number() you want?

Ämne: Onfly, function generated ID for Select Query
Dear Members!
I'm searching for a simple solution, like this:
select GetIDForThisSelect(1, 1) as UID, * from anytablehasdoublestringkey
join othertablehasnotuniqueintegerkey ...
where ....
Ok, I can make a sequence, but I don't want to use persistent data.
It is enough to get 1...N as UID for this select.
Like generate_series, but that is generating rows.
Maybe you have some trick to do this.
Thank you for any assistance!
Best regards
dd
