Error description

• When a UDF is invoked with a default parameter (either
  implicitly or explicitly), and the UDF is itself an argument to
  an aggregate function, and the query is within SQL PL or PL/SQL,
  SQLCODE -120 may be returned, e.g.:
  
      CREATE OR REPLACE FUNCTION fdef(
        IN p_int integer default 9909 )
      RETURNS integer
      LANGUAGE SQL NO EXTERNAL ACTION
      DETERMINISTIC
        BEGIN
        RETURN p_int; --
        END
      DB20000I  The SQL command completed successfully.
  
      create or replace function f()
      returns int
      language sql
      BEGIN
        DECLARE l_rtn CURSOR; --
        DECLARE result int; ---
        SET l_rtn = CURSOR FOR SELECT max(FDEF(DEFAULT))
                               FROM T group by col1; --
        OPEN l_rtn; --
        fetch l_rtn into result; --
        CLOSE l_rtn; --
        return result; --
      END
      SQL0120N  Invalid use of an aggregate function or OLAP
  function.
  

Local fix

• Do not make use of the DEFAULT value, add an explicit argument.
