this one helps. Well, you use a database.
Databases implement ACID properties (see here). To the extent possible, these guarantee the integrity of the data, even when transactions are not complete.

How to make an SQLite database as part of the build process - iPhone SDK

hope this fix your issue If you have an existing sqlite-store file you just add it to the app bundle just like you would any resource e.g. images, audio, etc.
If it is read only, you just use the NSBundle commands to supple a path to it inside the readonly app bundle. If you want it writable, you copy the store file from inside the app bundle to one of the writable app directories e.g. Documents or Library, and then open it there as you normally would.

Is there a more robust way to make join queries in Android / Java / SQLite?

I think the issue was by ths following , There is never a need to use string concatenation; rawQuery() supports parameters, too. (Parameters are passed directly into the database, without having to format them.)
cursor = db.rawQuery("SELECT * FROM a JOIN b USING (id) WHERE name = ?",
                     new String[]{ name });

Make OracleDataSource robust against Database restarts and hickups

hope this fix your issue I guess you have to do it on the JMS level, not DB level.
Not sure what type of listener you are using, but a DefaultMessageListenerContainer in Spring is implemented with a consumer.receive(timeout) loop. It's more robust than using a plain listener as it will attempt to reconnect on each poll cycle (if needed).

Delete tuples from postgress association table using SQLAlchemy

wish help you to fix your issue What you're trying to remove is a (group_id, donor_id) tuple. There's no reason for you to need to manually operate on groups_donor_table at all because the relationship group_donors already handles it for you. What you need to remove from group_donors is not the (group_id, donor_id) tuple, but the Donor instance that has an id equal to donor_id.
A more straightforward way to do this is to simply build a new list of donors that should be kept:
donor_ids_set = set(donor_ids)
group.group_donors = [donor for donor in group.group_donors if donor.id not in donor_ids_set]
