I have read that "read commited" should not be used, because it
is "broken".

I have read that I should use "snapshot".

If using snapshot is the correct choice (for possible queries that my
sit on a users display for hours), then what would be the correct
settings to use for this transaction type when using the following:

1. Firebird API
2. ODBC
3. OLEDB

I think this information written in a clear manner could help a lot of
people from getting "stuck" transactions.

Thanks
