[Zope] ZSQL Method Question

[Carlson, Christopher W.]

Following your recommendation, I get the following:

Zope has encountered an error while publishing this resource. 

Error Type: AttributeError
Error Value: __getslice__

Traceback:

I'll keep poking at it...  Thanks for the tip!

You could try the python "slice" operator, ie. to get the third row, use

<dtml-in "row[2:3]">

this gets a one-row sequence of third row only out of rows.
