Question

我的表包含数据以及日期创建。我想根据两个给定的日期范围或一个特定月份从表格中选择数据。

我不知道该怎么做，因为在列上创建的是text类型并存储为dd-MM-yyyy HH：mm：ss

我正在使用rawQuery（）来获取数据。

Answer 1

您可以这样做：

 mDb.query(MY_TABLE, null, DATE_COL + " BETWEEN ? AND ?", new String[] {
                minDate + " 00:00:00", maxDate + " 23:59:59" }, null, null, null, null);

minDate和maxDate（日期字符串）构成您的范围。此查询将获取MY_TABLE中属于此范围的所有行。

这是一些有用的

 //Get Trips Between dates
public List<ModelGps> gelAllTripsBetweenGivenDates(String dateOne, String dateTwo) {
    List<ModelGps> gpses = new ArrayList<>();
    SQLiteDatabase database = dbHelper.getReadableDatabase();
    final String columNames[] = {DBHelper.COLUMN_ID, DBHelper.COLUMN_NAME, DBHelper.COLUMN_LATITUTE, DBHelper.COLUMN_LONGITUDE, DBHelper.COLUMN_ALTITUDE, DBHelper.COLUMN_DATE, DBHelper.COLUMN_TYPE, DBHelper.COLUMN_TRAVEL, DBHelper.COLUMN_SPEED};
    String whereClause = DBHelper.COLUMN_TYPE + " = ? AND " + DBHelper.COLUMN_DATE + " BETWEEN " + dateOne + " AND " + dateTwo;
    String[] whereArgs = {"Trip"};

    Cursor cursor = database.query(DBHelper.TABLE_NAME_GPS, columNames, whereClause, whereArgs, null, null, DBHelper.COLUMN_NAME + " ASC");
    while (cursor.moveToNext()) {
        ModelGps gps = new ModelGps();
        gps.setId(cursor.getLong(cursor.getColumnIndex(DBHelper.COLUMN_ID)));
        gps.setName(cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_NAME)));
        gps.setLatitude(cursor.getDouble(cursor.getColumnIndex(DBHelper.COLUMN_LATITUTE)));
        gps.setLongitude(cursor.getDouble(cursor.getColumnIndex(DBHelper.COLUMN_LONGITUDE)));
        gps.setAltitude(cursor.getDouble(cursor.getColumnIndex(DBHelper.COLUMN_ALTITUDE)));
        gps.setDate(cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_DATE)));
        gps.setType(cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_TYPE)));
        gps.setTravel(cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_TRAVEL)));
        gps.setSpeed(cursor.getString(cursor.getColumnIndex(DBHelper.COLUMN_SPEED)));
        gpses.add(gps);
    }
    database.close();
    cursor.close();
    return gpses;
}
