You need an external method to get the dictionary object that has the field name to 
column number 


Here is the external method:
---------------------------------
def doPySQL(self, zQry) :
    tvar1 = 'res=self.'+zQry
    exec tvar1
    return res._schema.items()
------------------------------------------
Here is a dtml document that uses the external method:
(getRes is what I call the external method in Zope)
This was for proof of idea - it is not pretty
-------------------------------------------------------------------
<html><head><title>Test</title></head><body>
<dtml-with "_.namespace(t1=getRes('Your_Query_Here()'))">
<dtml-var "_.len(t1)"> Columns<br>
<dtml-var "_.str(t1)" html_quote><br><br>
<dtml-in t1>
<dtml-var "_.str(_['sequence-key'])"> = <dtml-var "_.str(_['sequence-item'])"><br>
</dtml-in>
<br><br>
</dtml-with>
</body></html>
</dtml-comment>
<html><head><title>Test</title></head><body>

<dtml-with "_.namespace(t1=Your_Query_Here(),t2=getRes('Your_Query_Here()'))">
<hr>
<dtml-in t1>
  <dtml-in t2 sort=sequence-item>
    <dtml-var "_['sequence-key']"> = <dtml-var "_.getitem(_['sequence-key'])" 
html_quote><br>
  </dtml-in><hr>
</dtml-in>
</dtml-with>
</body></html>

Ok... someone may have already answered this, but here's my guess.  (Yes, 
this is untried, sorry :)

<dtml-in "sqlQueryBlah()">
  <dtml-in sequence-item>
    <dtml-var sequence-key> = <dtml-var sequence-item>
  </dtml-in>
</dtml-in>

I'm certain this was tackled some time in the past, but yeh, searching the 
list logs can sometime be suprisingly fruitless.
