Hello all,
I'm using the following pattern for db access that requires me to
close the connection as soon as it is not needed:
import sqlite3 as lite
try:
db = lite.connect('data.db')
except lite.DatabaseError:
raise OSError('database file corrupt

A lot of patronizing egos running around in these groups. This is a
sad thread...
What is being asked is for help, not whether this is useful or needed.
Jan-Hein is after some directions, not whether your bloody opinion on
how he should use his free time.

It's actually parameterized views that I meant. Not queries. SQLite
misses the ability to write parameterized views.

Nevermind. I found the problem. In order to document the source code
it needs to be used in conjunction with sphinx-apidoc.

I'd say the diamond pattern is messy. MI is otherwise a pretty

Currently i'm using the following code to transform a row fetched from an
sqlite database into a dictionary property:
def __init__(self, id_):
self.id = id_
self.data = None
...
conn = sqlite3.connect('data')
conn.row_factory = sqlite3.Row
row = conn.
