如何比较以文本形式存储的sqlite中的日期和时间？

Question

我在 sqlite 数据库中有一列以这种格式 (YYYY-MM-DD HH:MM) 存储日期和时间。当我尝试将此列与另一个日期和时间值进行比较时，我的应用程序崩溃了。我猜这是因为 (HH:MM) 中存在冒号。我该如何比较？

查询：

public Cursor fetchrDatetime(String dati) throws SQLException {

       String query = "SELECT * FROM reminders WHERE reminder_date_time=" + dati;
       Cursor cursor = mDb.rawQuery(query, null);

       return cursor;
   }

WHERE 的值应介于 '.

String query = "SELECT * FROM reminders WHERE reminder_date_time='" + dati + "'";
