[Zope] Error calling a Z SQL method

[Cliff Ford]

This looks wrong to me, even if you have used it before. I would use the 
query like this:

<dtml-in retrieve_data_sql>
<dtml-var Column1> <dtml-var Column2> <br>
</dtml-in>

The REQUEST object is available to the ZSQL Method so you don't need to 
pass it explicitly. And you don't really need two DTML thingies - one 
will do.
