This problem seems to come up once in every few weaks --> an FAQ.

Okay, again:

  ZSQL methods are stupid, in that they only look at
  the REQUEST object and not at the namespace to find
  their arguments.

You could avoid this weakness by:

 1. <dtml-var "InsertFoo(a_id=a_id, b_id=b_id, c_id=c_id)">

    This provides the arguments explicitely.

 2. <dtml-call "REQUEST.set('a_id',a_id)">
    <dtml-call "REQUEST.set('c_id',c_id)">
    <dtml-var InsertFoo>

    This puts the argument values into the REQUEST object.
