獲取同一列和單個 MySQL 查詢中兩個單獨日期范圍的值的總和

Question

我有如下表，我正在嘗試編寫單個查詢來獲取日期范圍數據以及價格總和。 我的表定義如下

銷售表

id_sale date       time
  1     2014-05-05 12.30 am  
  2     2014-05-06 10.30 am 
  3     2014-05-25 12.30 am   

銷售產品表

   id_sale_product id_sale price  quantity  id_product
      1              1     10.00   1           1
      2              1     20.00   1           2
      3              2     20.00   3           5
      4              3     20.00   4           6

我想按銷售表中的日期過濾並獲得每個日期的價格總和 * 數量 = 總和，即 2014-05-05,2014-05-06..etc

我試過下面的查詢

$query = 'SELECT sp.`id_product_type`,sp.`id_product`,sp.`quantity`,sp.`price`,s.`date`
              , SUM(IF(s.`date` BETWEEN "'.$datepickerFrom.'" AND "'.$datepickerTo.'",sp.`price` * sp.`quantity`,0)) AS A
              FROM `'._DB_PREFIX_.'sale_product` sp
              LEFT JOIN '._DB_PREFIX_.'sales s ON (sp.id_sale = s.id_sale) 
              WHERE (s.`date` BETWEEN "'.$datepickerFrom.'" AND "'.$datepickerTo.'")';

輸出應該是：

Example: Date
01/01/2013    Rs.10000
02/01/2013    Rs.140000
03/01/2013    Rs.8000

Example: Month
January     Rs. 2,00,000
Feburary    Rs. 2,20,000

Answer 1

嘗試這個 ....

select a.date,sum(b.qty * b.price) As sum from sales As a, product As b where DATE_FORMAT(a.date,'%d-%m-%Y') between '27-05-2014' AND '28-05-2014' and a.id_sale=b.id_sale group by a.date
