[Zope] how do I get field names from a query

how do I get the names of the fields returned from a SQL query ? ( I would like to generate stuff using the names automatically) I know they must be available because I can use them directly ! I've tried lots of alternatives of the form <dtml-in "sqlListTable(table_name='personnel')"> <dtml-in sequence-item> <P><dtml-var sequence_item> </dtml-in > which give me the values but not the names, and looked through lots of the old msgs. Thanks in advance if anyone can help adam adam.molyneaux@epfl.ch
