      Description

      Derby in embedded mode does not support scroll sensitive resultsets in both read-only and updatable modes. But when I write a simple test program in Network Server configuration, it appears that scroll sensitive resultsets are supported both in read-only and updatable modes. Is that correct?

      Connection con = DriverManager.getConnection("jdbc:derby:net://localhost:1527/db1drda;create=true:retrieveMessagesFromServerOnGetMessage=true:deferPrepares=false;", "app", "app");
      Statement s = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY);
      SQLWarning warnings = con.getWarnings();
      while (warnings != null)
      {
      System.out.println("warnings on connection = " + warnings);
      warnings = warnings.getNextWarning();
      }
      System.out.println("Did we get TYPE_SCROLL_SENSITIVE? " + (s.getResultSetType() == ResultSet.TYPE_SCROLL_SENSITIVE));
      System.out.println("Did we get CONCUR_READ_ONLY? " + (s.getResultSetConcurrency() == ResultSet.CONCUR_READ_ONLY));

      s = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
      System.out.println("Did we get TYPE_SCROLL_SENSITIVE? " + (s.getResultSetType() == ResultSet.TYPE_SCROLL_SENSITIVE));
      System.out.println("Did we get CONCUR_UPDATABLE? " + (s.getResultSetConcurrency() == ResultSet.CONCUR_UPDATABLE));

      And the output in Network Server mode for above test case is
      Did we get TYPE_SCROLL_SENSITIVE? true
      Did we get CONCUR_READ_ONLY? true
      Did we get TYPE_SCROLL_SENSITIVE? true
      Did we get CONCUR_UPDATABLE? true
