mysqlのタイプc_date
として列を持つテーブルがあり、毎日の売上、各月の合計売上、および売上がなかった日、月、年を含む年間の合計売上を出力したいと考えています。datetime
total
int
現在、毎日の販売のために、以下のクエリを実行しています:
mysql> select date(c_date) as date, sum(total) as total_sale from sale group by date;
+------------+------------+
| date | total_sale |
+------------+------------+
| 2013-10-3 | 798 |
| 2013-10-6 | 114 |
+------------+------------+
しかし、私はこのようなものが欲しい:
mysql> select date(c_date) as date, sum(total) as total_sale from sale group by date;
+------------+------------+
| date | total_sale |
+------------+------------+
| 2013-10-1 | 0 |
| 2013-10-2 | 0 |
| 2013-10-3 | 798 |
| 2013-10-4 | 0 |
| 2013-10-5 | 0 |
| 2013-10-6 | 114 |
+------------+------------+
毎月の場合、私はこれを取得しています:
mysql> select c_date, month(c_date) as month, year(c_date) as year, sum(total) as total from sale group by c_date order by c_date;
+---------------------+-------+------+-------+
| c_date | month | year | total |
+---------------------+-------+------+-------+
| 2013-10-3 02:40:06 | 10 | 2013 | 228 |
| 2013-10-3 02:41:58 | 10 | 2013 | 114 |
| 2013-10-3 02:44:36 | 10 | 2013 | 114 |
| 2013-10-3 02:46:40 | 10 | 2013 | 114 |
| 2013-10-3 02:49:15 | 10 | 2013 | 114 |
| 2013-10-3 02:53:36 | 10 | 2013 | 114 |
| 2013-10-6 07:43:27 | 10 | 2013 | 114 |
+---------------------+-------+------+-------+
しかし、私はこのようなものが欲しい:
mysql> select c_date, month(c_date) as month, year(c_date) as year, sum(total) as total from sale group by c_date order by c_date;
+---------------------+-------+------+-------+
| c_date | month | year | total |
+---------------------+-------+------+-------+
| 2013-1-3 02:40:06 | 1 | 2013 | 0 |
