I need to move the changes in a table from one database to another. It seemed that fast snapshots would be a good way to do this as the database will automatically keep track of the changes for me. The question is that once I move the data to the snapshot side, I need to manipulate it, move it into another table, and start the cycle again. This means truncating the snapshot between refreshes. I tried this on a test system and it seesm to work, but I don't think Oracle supports it. I don't want updatable snapshots as this is strictly one way movement of data. Has anyone else tried this? Are there any potential problems? I think I am just truncating a table underlying the snapshot view so I don't see what could go wrong.

Thanks.
