DB2. Создание шаблона функции?

CREATE FUNCTION DB2ADMIN.MY_FUNCTION(
  INTEGER,
  DATE )
RETURNS TABLE  (
  A DECIMAL(20, 10),
  B DECIMAL(20, 10) )
AS TEMPLATE
DETERMINISTIC
NO EXTERNAL ACTION;

SQL0104N  An unexpected token "TABLE or ROW" was found following "RETURNS".  Expected tokens may include:  "Data types supported by CREATE FUNCTION(template)".
