pysqlite2.dbapi2.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 0, and there are -1 supplied.

[F. GEIGER]

Im on Python 2.3.4, using pysqlite 2.0.0 (final).

When I try to execute

self._dbc.execute(q, data)

where q is 'select count(*) from Difflets ' and date is None

I get the following exception:

pysqlite2.dbapi2.ProgrammingError: Incorrect number of bindings supplied.
The current statement uses 0, and there are -1 supplied.

Any ideas?

Many thanks in advance and kind regards
