[SQL] Help with Procedures in pgsql

[Nelio Alves Pereira Filho]

 
 I have the folowing procedure in PL/pgsql:
 
CREATE FUNCTION set_counter () RETURNS INT AS '
DECLARE 
        nivel_rec record;
        new_count integer;
BEGIN
        UPDATE 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 says
 IFX=# select set_counter();
 ERROR:  Attribute 'nivel_rec' not found
 
 Isn't that 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
