Thread: Help with Procedures in pgsql

I have the folowing procedure in PL/pgsql:
CREATE FUNCTION set_counter () RETURNS INT AS '
DECLARE nivel_rec record;new_count integer;
BEGINUPDATE nivel SET count=-2;
FOR nivel_rec IN SELECT * FROM nivel LOOP    new_count := set_counter_row (nivel_rec);    END LOOP;
RETURN new_count;
END;'
LANGUAGE 'plpgsql';
I create it, but when I do 'select set_counter()', it saysIFX=# select set_counter();ERROR:  Attribute 'nivel_rec' not
foundIsn'tthat the right sintax to declare variables in pgsql? What's wrong
 
with it?Does my procedure contain any other errors that will appear later?

Thanks

I always used the syntax like:
nivel_rec nivel%ROWTYPE;

Not sure it matters though.

I don't know what set_counter_row() is doing so the problem could be in that 
function.
