Need to pass dtml-in parameter

[Andre Dourado]

I´m a newbie in Zope and I have a little problem.

I'm trying to use a dtml-in tag to call a ZSQL, but the name of my
ZSQL is stored in a sql table.

I've tried things like:

<dtml-in expr=<dtml-var my_query>> where my_query is the column name
of my sql table where the ZSQL name is stored.

Thanks for any help.
