[Zope] Can I have 'pointers' to ZSQL Methods?

I need to do something like this: <dtml-in "<dtml-var qry_name>" or <dtml-in "_['<dtml-var qry_name>']"> where qry_name contains the name of the ZSQL Method that I want to use. However neither of the above works, the latter gives a traceback error, which I daren't reproduce here because of it's length :) The above is used inside a DTML Method which is called by passing parameters to it from a DTML Document. qry_name is one of the parameters being passed. Any help appreciated. thanks - Jason Wong Digital View Ltd 2201 Nanyang Plaza 57 Hung To Road Kwun Tong HONG KONG Tel: +852-2861-3615 Fax: +852-2520-2987 www.digitalview.com
