Обсуждение: PLPGSQL Returning Records

Hi,
I am trying to return a recod from from my function but for some reason
it does not work.

Here is may problem. I use a for loop to generate the first batch of
records. Once the loop is completed I want to add another record. But at
that point fails.

....

FOR  rec IN SELECT ....
LOOP

  RETURN NEXT r;
END LOOP;

do some assignments
RETURN r;

....

It seems that the function does not return anything after the loop. Can
anyone help me on that ?

Thanks
Alex

I think you want RETURN NEXT r; (or rec) to add the record to the
set of output rows.
