Using sqlite3 python and I have a problem running a query.
My table has null values. Now if I do a 'select * from tablename' returns
to me as the result:
[(datetime.date (2012, 3, 22), buffer ptr read-write 0x03774B90,
0x03774B58 at size 0, None, None, None, None, None, None)]
As
select * from tablename where field1 IS Null

NULL is never equal any value, not even another NULL.

I did show this very example, except lacking the whitespace in front
and differing in capitalization. I assume you feel those distinct
characteristics render your example more interesting than mine.
Or mine, which was sent minutes before Igor's. Hmph. ;)
