If I make a ResultSet Updatable, and then make changes to the ResultSet, does that actually change the database as well or do I still have to update the database? I didn't know if a ResultSet was just a cached dataset from the database or if it was still connected. Thanks.
A ResultSet is still connected to the database. To update an updatable ResultSet, you would have to call ResultSet.updateRow() after you made the changes. When you call methods like ResultSet.updateString( int, String), nothing happens to the database (except maybe locking the row, depending on the ResultSet cursor parameters and the database driver).
