Hi,
I can't see any obvious reasons for your problems, I'm afraid, but I
do have a comment on your SQL: the sqlite module supports using ? to
indicate parameters. So you could rewrite your select statements as:
cur.execute("select code from codes where code != '' and style = ? and
start >= ? and start < ?", (style, self.start_datestring,
self.end_datestring))
which is much easier to read, and also not vulnerable to SQL injection.
Secondly, any reason why you aren't getting both code and start in a
single select statement? i.e.
cur.execute("select code, start from codes where code != '' and style
= ? and start >= ? and start < ?", (style, self.start_datestring,
self.end_datestring))
(heck, you could select code, start, style form codes -- pull all the
information you need in a single query, and skip the loop
altogether..)
