This is FAQ material and should be inserted into either the DTML programmer's guide
or the ZSQL Methods guide.  It bites everyone who uses SQL methods eventually.

ZSQL methods do not perform acquisition, but will look at REQUEST, change it
to.
<dtml-in "active_category_method()">
     <dtml-call "REQUEST.set('id', id)">
     <dtml-in "category_method()" size=100 start=query_start>
         id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid>
     </dtml-in>
 </dtml-in>

If you have a lot of arguments that need to be captured, you can
build a DTML Method, say setup_category_method_parameters that
has these builds the REQUEST.  Then your dtml can look like:
<dtml-in "active_category_method()">
     <dtml-call setup_category_method_parameters>
     <dtml-in "category_method()" size=100 start=query_start>
         id=<dtml-var id>&seq=<dtml-var seq>&vid=<dtml-var vid>
     </dtml-in>
 </dtml-in>
