在查询SQL

Question

很难搜索到它非常具体，我目前在使用我的查询时看到下面的数据集，问题是在net栏下这应该是每个产品的净值加起来（数据集会显示什么我的意思是），但我无法实现这一点，在工作时我还想为此添加一个thrid列并将值相加，所以重要的是要做到这一点。

当前查询：

SELECT
    product, Net,
    COUNT(OrderNumber) AS CountOf
FROM
    orders
WHERE
    STATUS = 'booking' AND
    Date(OrderDate) <= CURDATE() AND 
    Date(OrderDate) > DATE_SUB(CURDATE(),INTERVAL 30 DAY)
GROUP BY
    product

数据集：

id | product | status  | Net
-----------------------------
1  | pd1     |quote    | 10
2  | pd2     |booking  | 15
3  | pd4     |booking  | 20
4  | pd2     |cancelled| 15
5  | pd2     |booking  | 15
6  | pd1     |booking  | 10
7  | pd1     |booking  | 10

当前结果集：

product | Sales  | Net
------------------------
pd1     |3        | 10
pd2     |3        | 15
pd4     |1        | 20

期望的结果集：

product | Sales  | Net
------------------------
pd1     |3        | 30
pd2     |3        | 45
pd4     |1        | 20

我认为这应该有意义

Answer 1

对Net列使用sum。这是你的解决方案：

SELECT
    product, sum(Net) as Net,
    COUNT(OrderNumber) AS CountOf
FROM
    sw_orders
WHERE
    STATUS = 'booking' AND
    Date(OrderDate) <= CURDATE() AND 
    Date(OrderDate) > DATE_SUB(CURDATE(),INTERVAL 30 DAY)
GROUP BY
    product

Answer 2

SELECT
    product, SUM(Net) AS Net,
    COUNT(OrderNumber) AS CountOf
FROM
    orders
WHERE
    STATUS = 'booking' AND
    Date(OrderDate) <= CURDATE() AND 
    Date(OrderDate) > DATE_SUB(CURDATE(),INTERVAL 30 DAY)
GROUP BY
    product
