Re: Help trying to write my first plpgsql function...

Oki, I found a way...

begin;
select trykkstatus(1,'refcurs'); (I have added one parameter to know the cursor name)
fetch all from refcurs;
commit;

But this returns two rowsets, first one for the select and then one for the fetch,
but how do I get rid of the row that is returned by the select?
