365/12 = 30.4
2006/03/31 - 30 days = 2006/03/01
just subtract 30 days and be done with it. i think you can justify that
to your customers.

I think the logic might have been to subtract the number of days in the
previous month from the current date. E.g.
2007/03/25 -28 (days in Feb) will give 2007/02/25 (spot on)
2007/10/31 -30 (days in Sept) will give 2007/10/01 (as good as you can

2007/09/30 -31 (days in Aug) will give
Look at the Sqlite date functions. File date.c describes them.
You may find that a custom function gives you exactly what you want.

An integer is always 64 bits.

Hi Cristopher,
Actually this will be updated throughout the software's cycle because we
need to always add new airports and information relating to them. Yup! You
got it running on Windows Vista. I will check out Active Python and see
what I can't come up with then.

In a threaded environment the simple and effective solution is to
synchronize your transactions with a mutex. You lose a little possible
concurrency but if you do not need it you simplify the logic no end and
have a more robust application.
Using pthreads you can improve a little by using

Requiring the second transaction to complete first is expected in
terms of SQLIte's concurrency system.
So in terms of using SQLite, I need to close the entire transaction and
restart it when I get a "database locked" return code in a writer
thread? It's not enough to just retry the commit in

I didn't think of that, but yes, that is a good suggestion.
I hope it helps the original poster.

Maybe this is implied, but you might also try to .DUMP tables

Please ignore my idiocy. I had quite forgotten they were in the 0th row.

I could use sqlite3_prepare with my statement string and then calls to
sqlite3_column_name() to build a mapping. I could then dispose of the prepared
statement and make my call to sqlite3_get_table, relying on the column
