[Zope-DB] Oracle cursor: integer required!

[centershock@t-online.de]

Ahoi people,

I want to connect an Oracl Database through an external Methode of
Zope. 
It is no problem to connect the database. I have a problem with the
cursor. If  I construct a Coursor and deliver a SQL-statement, Zope
reports:

Error Type: TypeError
Error Value: an integer is required

code:
c = db.cursor()
c.execute("select * from test")

Environment:
OS: Win2k
Zope 2.6.0
Oracle 8.0


If someone have an Idea what's the Problem, please mail me.
