[SQLObject] Creating new objects in pre-existing table

[luis c. <lo....@gm...>]

I have a pre-defined table in a SQL Server database that contains 4 columns
+ the primary key (integer).  My class in Python is defined as:

class HistoricalMatrix(SQLObject):
    class sqlmeta:
        fromDatabase = True
        table="HistoricalMatrix"
    ccy = StringCol(length = 4)
    dataDate = DateCol()
    handle = StringCol(length = 128)
    coeff = StringCol()

the columns in the database are:
id
ccy
data_date
handle
coeff

The data_date column is specified as "data_date" in the database - is there
a way I can specify this in the class definition? I came about using the
mixed-case setup after some errors declaring the field as data_date in my
Python class.
