This means that if you are replacing a record that is a member of a sorted duplicates set, and if you are using the default lexicographic sort, then the replacement will fail due to violating the sort order. However, if you provide a custom sort routine that, for example, sorts based on just a few bytes out of the data item, then potentially you can perform a direct replacement and still not violate the restrictions described here. </p> <p> <span>Under these circumstances, if</span> you want to replace the data contained by a duplicate record, <span> and you are not using a custom sort routine, then </span> delete the record and create a new record with the desired key and data. </p> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="DeleteEntryWCursor.html">Prev</a> </td> <td width="20%" align="center"> <a accesskey="u" href="Cursors.html">Up</a> </td> <td width="40%" align="right"> <a accesskey="n" href="cursorJavaUsage.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">Deleting Records Using Cursors </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> Cursor Example</td> </tr> </table> </div> </body> </html>
