An FAQ (--> searchable mailing list archives):

  Z SQL Methods do *not* look into the DTML namespace for their
  arguments.

  You have 3 options:

    1.  explicitly passing the parameters as keyword (!) arguments

    2.  passing a mapping as single positional argument.
        The mapping contains all arguments

    3.  putting the arguments in the REQUEST object, aka:

	   <dtml-call "REQUEST.set(<paramname>,<paramvalue>)">

	and calling the method implicitly.
