[SQLObject] How do I do a LEFT JOIN?

[Mark M. <ma...@di...>]

Hi all,

I am super-excited about this package, but I can't seem to figure out how 
do execute a simple LEFT JOIN SQL query.  Am I missing somehting basic 
here?  I have my two tables set up, but I can't issue the SQL directly with 
the .select() method because it throws that pesky WHERE in at the end.  
Here is what I am getting:

class Customer(SQLObject):
    _table = "customer"
    _idName = "custid"
    Company     = StringCol(length=30, dbName='company', default="")
    Street      = StringCol(length=35, dbName='street', default="")
    City        = StringCol(length=20, dbName='city', default="")
    Province    = StringCol(length=15, dbName='province', default="")
    PostalCode  = StringCol(length=7, dbName='pcode', default="")
    Contacts    = MultipleJoin('Contact', joinColumn='custid', 
orderBy=['LastName', '-Title', 'FirstName'])

class Contact(SQLObject):
    _table = "contacts"
    _idName = "contactid"
    LastName    = StringCol(length=15, dbName='last_name', default="")
    FirstName   = StringCol(length=15, dbName='first_name', default="")
    Title       = StringCol(length=25, dbName='title', default="")
    Customer    = ForeignKey('Customer', dbName='custid', default=0)

if __name__ == '__main__':
    all = Customer.select("""JOIN ON Contacts USING (custid)""")

Gives me:

Select:  SELECT customer.custid, customer.province, customer.city, 
customer.stre
et, customer.pcode, customer.company FROM customer WHERE JOIN ON Contacts 
USING
(custid)

Can anyone point me in the right direction?  I need the LEFT JOIN behaviour 
here, not a simple equi-join, as there may be Customers defined, but no 
Contacts.

Thanks a lot,
Mark.
