Java SQLite'；介于'之间；不'；I don’我没有表现得像预期的那样

我试图选择两列值之间的所有行。这些值是UNIX时间戳，但查询根本不返回任何行。为什么会这样

这是我的密码：

public static ArrayList<Appointment> getAppointments(long start, long end) {
    ArrayList<Appointment> appointments = new ArrayList<>();
    try {
        Statement stat = db.createStatement();
        System.out.println("\n" + start + "  ->  " + end);

        // debugging only
        try (ResultSet rs = stat.executeQuery("SELECT * FROM appointments;")) {
            while (rs.next()) {
                long time = rs.getLong("date");
                if (time >= start && time <= end) {
                    System.out.println("Should be adding to list");
                }
            }
        } // 

        try (ResultSet rs = stat.executeQuery("SELECT * FROM appointments WHERE date BETWEEN " + start + " AND " + end + ";")) {
            while (rs.next()) {
                System.out.println("ADDING");
                appointments.add(new Appointment(rs.getLong("date"), rs.getInt("duration")));
            }
        }
    } catch (SQLException ex) {
    }
    System.out.println(appointments);
    return appointments;
}

输出为：

date = 1347390000000 duration = 15
date = 1347461100000 duration = 30
date = 1347469200000 duration = 45

1350141222283  ->  1350746022283
[]

1349536422283  ->  1350141222283

1348931622283  ->  1349536422283

您必须声明列的数据类型。

您在盲目地捕获SQLExceptions。不要那样做。放一些至少报告它们是什么的代码。我省略了catch代码，因为它与问题无关。至于输出，据我所知，它是完全合理的。[]是每次搜索范围更改时（每周）该方法返回的内容。+1回到问题，我不确定发生了什么，因为查询在SQL FIDLE上工作。现在一切都是System.out，因为out和err不同步，这就是顺序混乱的原因。对此表示歉意有趣的是，它在SQL Fiddle上工作，我觉得这是我在某个地方遗漏的一个小细节。也许“日期”列在数据库中没有定义得那么长？这可能会导致意外行为。

date = 1347390000000 duration = 15
date = 1347461100000 duration = 30
date = 1347469200000 duration = 45
