-        be part of one or more Table objects defined on the DAL object.
-        The "fields" list can include one or more DAL Table objects in addition
-        to or instead of including Field objects, or it can be just a single
-        table (not in a list). In that case, the Field objects will be
-        extracted from the table(s).
+        Added 2012-08-24 "fields" and "colnames" optional arguments. If either

+        converted to a DAL Rows object using the db._adapter.parse() method.

+        list). In that case, the Field objects will be extracted from the
+        table(s).
 
-        The field names will be extracted from the Field objects, or optionally,
-        a list of field names can be provided (in tablename.fieldname format)
-        via the "colnames" argument. Note, the fields and colnames must be in
-        the same order as the fields in the results cursor returned from the DB.
+        Instead of specifying the "fields" argument, the "colnames" argument
+        can be specified as a list of field names in tablename.fieldname format.
+        Again, these should represent tables and fields defined on the DAL
+        object.
+        
+        It is also possible to specify both "fields" and the associated
+        "colnames". In that case, "fields" can also include DAL Expression
+        objects in addition to Field objects. For Field objects in "fields",
+        the associated "colnames" must still be in tablename.fieldname format.
+        For Expression objects in "fields", the associated "colnames" can
+        be any arbitrary labels.
+        
+        Note, the DAL Table objects referred to by "fields" or "colnames" can
+        be dummy tables and do not have to represent any real tables in the
+        database. Also, note that the "fields" and "colnames" must be in the
