[Zope] Getting SQL record names in python script?

[azbok@yahoo.com]

I call a ZSQL method in python and successfully retrieve the results I 
want.  Then I want to get a list of the field names.

I try
  MyRec = context.GetRecord()
  print MyRec[0].keys()

I get 
  Error Type: AttributeError
  Error Value: keys

I can cycle through the values no problem.  I thought the records 
returned were each a dictionary.  Is keys one of those functions that 
is restricted?

How would I get field names?

Thank you very much
