has changed. This method may be called after calling an
<code>updateXXX</code> method(s) and before calling

the updates made to a row.  If no updates have been made or
<code>updateRow</code> has already been called, this method has no
effect.

           (2) this method is called when the cursor is
            on the insert row, or (3) this rowset does not
            currently have a valid connection, prepared statement,
            and result set
