Question

我正在研究一个项目而且我创建了这个sql查询但是如果我选择一个更大的日期范围似乎需要太长时间，任何想法如何让它更快，我尝试使用union all并且它更快，但数据不一样，需要帮助代码：

SELECT SUM(ROUND(total, 2)) as Enero from (
    SELECT 
    FORMAT (
    COALESCE(
    CONCAT(ROUND(pro.precio / 1.14 , 2) + ROUND(p.recargo / 1.14 , 2) + (SELECT SUM(ROUND(precio / 1.14 , 2)) AS precio FROM acompanante_orden WHERE id_orden=p.id_orden) - p.descuento),
    CONCAT(ROUND(pro.precio / 1.14 , 2) + ROUND(p.recargo / 1.14 , 2) - p.descuento) 
    )+ COALESCE(

    ROUND(CONCAT(ROUND(pro.precio / 1.14 , 2) + (SELECT SUM(ROUND(precio / 1.14 , 2)) AS precio FROM acompanante_orden WHERE id_orden=p.id_orden) + ROUND(p.recargo / 1.14 , 2) - p.descuento) * 0.14, 2), 
    ROUND(CONCAT(ROUND(pro.precio / 1.14 , 2) + ROUND(p.recargo / 1.14 , 2) - p.descuento) * 0.14, 2)
    ), 2) as total


    FROM orden p
    LEFT JOIN producto_orden AS pro ON p.id_orden = pro.id_orden
    LEFT JOIN acompanante_orden AS pa ON p.id_orden = pa.id_orden

    WHERE p.actual_date BETWEEN '2017-04-01' AND '2017-04-01' and p.status=4 
) sum_1

UNION ALL IDEA

select ROUND(( sum(precio)) * 1.14,2) as total from (
    SELECT a.id_orden, ROUND(b.precio / 1.14 , 2) + ROUND(a.recargo / 1.14 , 2) - a.descuento as precio FROM orden a, producto_orden b WHERE a.id_orden=b.id_orden and a.actual_date BETWEEN '2017-04-01' AND '2017-04-01' and a.status=4 union all
    SELECT c.id_orden, ROUND(d.precio / 1.14 , 2) as precio FROM orden c, acompanante_orden d WHERE c.id_orden=d.id_orden and c.actual_date BETWEEN '2017-04-01' AND '2017-04-01' and c.status=4
) sum_1

这是我的表架构：http://sqlfiddle.com/#!9/4fe12/2

我需要什么：

我需要获得每月卖出的总数，但是数据库上的值与TAXES一样，所以在我得到总数之前我需要做一些数学运算：

数据库信息

PRODUCT= $50.00
ADDONS= $8.00
SHIPPING= $6.00

DISCOUNT= $2.00

结果我需要：

PRODUCT= $50.00 / 1.14 = $43.86
ADDONS= $8.00 / 1.14 = $7.02
SHIPPING= $6.00 / 1.14 =$5.26

SUBTOTAL= $56.14 - DISCOUNT($2)= $54.14

SUBTOTAL= $54.14 * 1.14 = $61.72

Answer 1

第一个子查询基本上是：

SELECT . . .
FROM orden p LEFT JOIN
     producto_orden pro
     ON p.id_orden = pro.id_orden LEFT JOIN
     acompanante_orden pa
     ON p.id_orden = pa.id_orden
WHERE p.actual_date BETWEEN '2017-04-01' AND '2017-04-01' and
      p.status = 4

对于此查询，您需要orden(status, actual_date, id_id_orden)上的索引，producto_orden（id_orden）, and acompanante_orden（id_orden）`。

我不确定查询的其余部分是什么。

mysql查询耗时太长
