将 SELECT 语句与每个语句中的聚合结合起来答案

【问题标题】：Combine SELECT statements with aggregates in each statement将 SELECT 语句与每个语句中的聚合结合起来

【问题描述】：

我想将 2 个有效的 sql 语句合并为一个，但我不知道如何完成。我正在使用 excel/odbc，只能读取 MS SQL SERVER。

第一句话：

 SELECT CustomerLocal.LocalCustomerID, 
        Sum(Orders.OrdersEURO) AS 'Sum of OrdersEURO'
FROM MyDataBase.dbo.CustomerLocal CustomerLocal, 
     CopelandDatabase.dbo.Orders Orders
WHERE Orders.LocalCustomerID = CustomerLocal.LocalCustomerID 
      AND Orders.Plant = CustomerLocal.Plant 
      AND ((CustomerLocal.IntExtCust In ('E')))
GROUP BY CustomerLocal.LocalCustomerID
ORDER BY CustomerLocal.LocalCustomerID

第二个语句是：

SELECT Sales.LocalCustomerID, 
SUM (CASE WHEN Sales.DateOfInvoice BETWEEN{ts '2012-10-01 00:00:00'} AND {ts '2013-09-30 00:00:00'} 
THEN Sales.SalesEURO
ELSE 0
END) AS Sales2013 ,
SUM (CASE WHEN Sales.DateOfInvoice >= {ts '2013-10-01 00:00:00'}  
THEN Sales.SalesEURO
ELSE 0
END) AS SalesYearToDate
FROM "dbo"."Sales"
Where Sales.DateOfInvoice >= {ts '2012-10-01 00:00:00'}
Group By Sales.LocalCustomerID
ORDER BY Sales.LocalCustomerID

希望的结果（列）：

LocalCustomerID, Sales2013, SalesYearToDate, Sum of OrdersEURO

如何开始两者的整合组合？，目前我只是在excel和vlookup中运行其余的。

编辑：替换了第二条语句，抱歉错误。

【问题讨论】：

这两个语句是一样的...！第二条sql语句是什么？
我们从中获取 YTD 和 2013 年数据的列的名称是什么？你希望它在某个时候切换到 2014 年吗？提示：如果Sales2013被称为SalesFullYear会更好
Sales2013 和 SalesYearToDate 是从哪里来的？
把陈述搞砸了，我应该多加注意的。非常抱歉。

【解决方案1】：

连接应该可以工作：

Select a.LocalCustomerID, b.Sales2013, b.SalesYearToDate, a.[Sum of OrdersEURO]
from
(
SELECT CustomerLocal.LocalCustomerID, 
       Sum(Orders.OrdersEURO) AS 'Sum of OrdersEURO'
FROM MyDataBase.dbo.CustomerLocal CustomerLocal, CopelandDatabase.dbo.Orders Orders
WHERE Orders.LocalCustomerID = CustomerLocal.LocalCustomerID AND Orders.Plant =   
CustomerLocal.Plant AND ((CustomerLocal.IntExtCust In ('E')))
GROUP BY CustomerLocal.LocalCustomerID
) a
JOIN
(
SELECT Sales.LocalCustomerID, 
SUM (CASE WHEN Sales.DateOfInvoice BETWEEN{ts '2012-10-01 00:00:00'} AND {ts '2013-09-30 00:00:00'} 
THEN Sales.SalesEURO
ELSE 0
END) AS Sales2013 ,
SUM (CASE WHEN Sales.DateOfInvoice >= {ts '2013-10-01 00:00:00'}  
THEN Sales.SalesEURO
ELSE 0
END) AS SalesYearToDate
FROM "dbo"."Sales"
Where Sales.DateOfInvoice >= {ts '2012-10-01 00:00:00'}
Group By Sales.LocalCustomerID
) b
ON a.LocalCustomerID=b.LocalCustomerID
ORDER BY a.LocalCustomerID

【讨论】：

关键字“JOIN”附近的语法不正确，“b”附近的语法也不正确。

【解决方案2】：

尝试使用联合声明

SELECT CustomerLocal.LocalCustomerID, 
    Sum(Orders.OrdersEURO) AS 'Sum of OrdersEURO'
FROM MyDataBase.dbo.CustomerLocal CustomerLocal, CopelandDatabase.dbo.Orders Orders
WHERE Orders.LocalCustomerID = CustomerLocal.LocalCustomerID AND Orders.Plant =     CustomerLocal.Plant AND ((CustomerLocal.IntExtCust In ('E')))
GROUP BY CustomerLocal.LocalCustomerID
ORDER BY CustomerLocal.LocalCustomerID
Union
SELECT CustomerLocal.LocalCustomerID, 
       Sum(Orders.OrdersEURO) AS 'Sum of OrdersEURO'
FROM MyDataBase.dbo.CustomerLocal CustomerLocal, CopelandDatabase.dbo.Orders Orders
WHERE Orders.LocalCustomerID = CustomerLocal.LocalCustomerID AND Orders.Plant =   
CustomerLocal.Plant AND ((CustomerLocal.IntExtCust In ('E')))
GROUP BY CustomerLocal.LocalCustomerID
ORDER BY CustomerLocal.LocalCustomerID

【讨论】：

暂时无法给出答案，因为问题中有一个错误：两条SQL语句是一样的。
