Sqlite内部結合は、各行の特定の列に同じ値を繰り返します。

私はdaybookとtradetableという2つのテーブルに対して内部結合の概念を使用している元帳型の値を表示しようとしました。日帳には、ユーザーが持っている金額、ユーザーが持っている前払い金額などの値が格納されています。Sqlite内部結合は、各行の特定の列に同じ値を繰り返します。

Daybookテーブル：

String CREATE_DAYBOOK = "CREATE TABLE " + DAYBOOK_DETAILS + "(" 
      + DAYBOOK_ID + " INTEGER PRIMARY KEY," 
      + DAYBOOK_DATE + " TEXT," 
      + DAYBOOKUSER_TYPE + " TEXT," 
      + DAYBOOK_AMOUNT_IN + " NUMERIC," 
      + DAYBOOK_AMOUNT_OUT + " NUMERIC," 
      + DAYBOOK_NAME + " TEXT," 
      + DAYBOOK_MOBILENO + " NUMERIC," 
      + DAYBOOK_DESCRIPTION + " TEXT," 
      + DAYBOOK_TYPE + " TEXT" + ");"; 
    db.execSQL(CREATE_DAYBOOK);

Tradetable：

String CREATE_TRADE_TABLE = "CREATE TABLE " + TRADE_LABELS + "(" 
      + TRADE_ID + " INTEGER PRIMARY KEY," 
      + TRADE_DATE + " TEXT," 
      + TRADE_FARMERNAME + " TEXT," 
      + TRADE_FMOBILENO + " NUMERIC," 
      + TRADE_BILLNO + " NUMERIC," 
      + COCONUT_NO + " NUMERIC," 
      + COCONUT_COST + " NUMERIC," 
      + TOTAL_AMOUNT + " NUMERIC," 
      + TRADE_ADVANCE_AMOUNT + " NUMERIC," 
      + BALANCE_AMOUNT + " NUMERIC," 
      + NOTES + " TEXT," 
      + SETTLED + " TEXT" + ");"; 
    db.execSQL(CREATE_TRADE_TABLE);

問合せ：

String selectquery = "SELECT daybookdetails.date,\n" + 
       "  IFNULL(amountin,0) AS tradetotal,\n" + 
       "  IFNULL(amountout,0) AS advancetotal,\n" + 
       "  IFNULL(advanceamt,0),\n" + 
       "  daybookdescription,\n" + 
       "  daybooktype\n" + 
       "FROM farmertradelabel\n" + 
       "INNER JOIN daybookdetails ON farmertradelabel.mobileno = daybookdetails.mobileno\n" + 
       "WHERE daybookname = '"+fname+"'\n" + 
       " AND daybookdetails.mobileno = '"+fmobno+"'\n" + 
       "GROUP BY daybookdetails.date\n" + 
       "ORDER BY daybookdetails.date ASC";

私は次のように述べ条件を与えている：

if (cursor.getString(3).startsWith("0")) { 
       ledgerView.setBalance(cursor.getString(2)); 
      } else { 
       double one = Double.parseDouble(cursor.getString(1)) - Double.parseDouble(cursor.getString(3)); 
       ledgerView.setAdvancegiven(String.valueOf(one)); 
       ledgerView.setBalance(cursor.getString(3)); 
      }

私が期待している

出力は次のようにする必要があります：
