>>However, I don't think, that it is a good idea to always save the complete cursor. You should check for changed records only and replace those in your database. So IMHO you should hang on to Craigs post.

Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are,
by definition, not smart enough to debug it.
