如何获得和之和与一个MySQL查询

Question

我有以下查询，给了我重新发布者的所有分组销售

SELECT 
    publisher_name, 
    SUM(sales) AS sales, 
    SUM(comission) AS comission, 
    SUM(sale_total) AS publisher_total_sale 
FROM reports_summary 
    GROUP BY publisher_name 
    ORDER BY publisher_total_sale DESC 

其输出

------------------------------------------------------------------------------- 
+ publisher_name + | + sales + | + commission + | publisher_total_sale_count + 
------------------------------------------------------------------------------- 
+ some publisher + | 254,12 + | + 12,23  + | 15       + 
------------------------------------------------------------------------------- 
+ publisher2  + | 123  + | + 23   + | 12       + 
------------------------------------------------------------------------------- 

我想要什么

另一列给我在这个例子中sum(publisher_total_sale_count) 27. +
是否有可能，会怎么样我这样做？

就可以计算出在一个子查询，然后使用一个交叉连接，使其您的主查询：

SELECT 
    publisher_name, 
    SUM(sales) AS sales, 
    SUM(comission) AS comission, 
    SUM(sale_total) AS publisher_total_sale, 
    sumOfTotalSales 
FROM reports_summary, 
    (SELECT Sum(Sales_total) as sumOfTotalSales FROM reports_summary) as subTotalSales 
    GROUP BY publisher_name, sumOfTotalSales 
    ORDER BY publisher_total_sale DESC 

要在GUI而不是SQL编辑器做到这一点，你可以创建一个新的查询做这里的子查询是什么SELECT Sum(Sales_total) as sumOfTotalSales FROM reports_summary然后将它带入您的主查询并确保两个表之间没有连接。
