			PreparedStatement ptmt = null;
			ResultSet rs = null;
			conn = DriverManager.getConnection("jdbc:oracle:thin:@10.1.252.80:1521:newngboss", "so1", "so1");

			ptmt = conn
					.prepareStatement("select ROWID,t.* from BAT_PRE_AUTHOR_TMP t where mod(BAT_PRE_AUTHOR_TMP_ID,2)=1 and check_state=1 and rownum <=100 ");
			ptmt.setFetchSize(100);
			rs = ptmt.executeQuery();
			while (rs.next()) {
				System.out.println(rs.getObject("VALID_DATE").getClass());
				rs.getObject("VALID_DATE");
			}
