I don't use remote views. The entire application is built on CursorAdapter. I am sure some will say that remove views are better than CA. And yet, others will say that CA is better. If it works, why break it :)

>What I've done in the past is use remote views for the different databases, then create a local view that contains the two remote views joined together -- I'm even doing updates this way. I have had others tell me that this is not necessarily a good idea -- however I've yet to ever have a problem doing it & been doing it for many many years. I actually have local view that contains remote views from DB2, MySQL, Oracle, two SQL databases and 2 VFP databases all wrapped into one local view lol.
