[jira] Closed: (DERBY-350) NPE when relative() is called for empty ResultSet

Posted by "Bernt M. Johnsen (JIRA)" <de...@db.apache.org>.
     [ http://issues.apache.org/jira/browse/DERBY-350?page=all ]
     
Bernt M. Johnsen closed DERBY-350:
----------------------------------

    Resolution: Duplicate

Duplicate of DERBY-276. The proposed patch for 276 missed the fact that according to JDBC spec, isBeforeFirst() and isAfterLast() both should return false when the result set is empty.
