from Shared.DC.ZRDB.Results.py:

     67         class r(Record, Implicit, brains, zbrains):
     68             'Result record class'
     69
     70         r.__record_schema__=schema
     71         for k in Record.__dict__.keys():
     72             if k[:2]=='__':
     73                 setattr(r,k,getattr(Record,k))
     74
     75         # Add SQL Aliases
     76         d=r.__dict__
     77         for k, v in aliases:
     78             if not hasattr(r,k): d[k]=v
     79
     80         if hasattr(brains, '__init__'):
     81             binit=brains.__init__
     82             if hasattr(binit,'im_func'): binit=binit.im_func
     83             def __init__(self, data, parent, binit=binit):
     84                 Record.__init__(self,data)
     85                 if parent is not None: self=self.__of__(parent)
     86                 binit(self)
     87
     88             r.__dict__['__init__']=__init__
     89
     90         self._class=r

This result set class is just an inner class definition in a list
alike class for the results.
Adding a column could be a little bit harder since the column name
is stored elsewhere. You should look in the definition of Record
and brains to find an interface for this.
