ORDERは、年DESCは私が日付フィールドで<code>table</code>を持っているSQLiteの

Question

に動作していないと私は月、年、日（3別々のcolumns）に変換しています。それはうまくいきますが、私は結果を月と年で降順で並べ替える必要があります。ここで

は私のクエリです： -

Cursor c = database.rawQuery(
    "select count(*) as TotalCount, tDate, " + 
     "sum(case when type = '1' then Amount else 0 end) \"Income\", " + 
     "sum(case when type = '2' then Amount else 0 end) \"Expenses\", " + 
     "(sum(case when type = '1' then Amount else 0 end) - sum(case when type = '2' then Amount else 0 end)) \"Profit\", " + 
     "strftime('%d', tDate) as DayPart, " + 
     "strftime('%m', tDate) as MonthPart, " + 
     "strftime('%Y', tDate) as YearPart " + 
     "from library " + 
     "group by MonthPart, YearPart Order by YearPart,MonthPart DESC", 
    null 
); 

それはだけMonthPartでないYearPartとMonthPartの両方で降順で表示されます。助けてください。

私は答えました： -

Cursor c = database.rawQuery(
    "select count(*) as TotalCount, tDate, " + 
      "sum(case when type = '1' then Amount else 0 end) \"Income\", " + 
      "sum(case when type = '2' then Amount else 0 end) \"Expenses\", " + 
      "(sum(case when type = '1' then Amount else 0 end) - sum(case when type = '2' then Amount else 0 end)) \"Profit\", " + 
      "strftime('%d', tDate) as DayPart, " + 
      "strftime('%m', tDate) as MonthPart, " + 
      "strftime('%Y', tDate) as YearPart " + 
      "from library " + 
      "group by MonthPart, YearPart ORDER BY date(tDate) DESC", 
    null 
);
