Implementation help (database application)

The above should help. Rather than replacing the database, have a set of tables that are the core information. either, use them attached, or attach your update database, get rid of the old info, and replace it from the new database.

so, for example, if you attach the database as "updates", you can then "insert into infotable select * from updates.infotable"

Hope this helps.

Very thanks tangential,
your solution is great and simple; I've tried it in the console for now, but it should work with qt. Only an updates to your query:

insert or replace into infotable select * from updates.infotable

This for avoid the unique primary key error.
