我有一个查询，结果如下

saledate    Amount    TRVal
20/05/2013  $6250.78  4
21/05/2013  $4562.23  4
22/05/2013  $565.32   6
23/05/2013  $85.36    8
24/05/2013  $56.36    5

我想要金额的平均值

saledate    Amount    TRVal  AvgVal
20/05/2013  $6250.78  4      2304.01
21/05/2013  $4562.23  4      2304.01
22/05/2013  $565.32   6      2304.01
23/05/2013  $85.36    8      2304.01
24/05/2013  $56.36    5      2304.01

我知道要计算平均值，但我希望它包含在查询结果中。

我正在使用的查询是

我试图添加 

 (SELECT avg(TotalValue) FROM SalesData) as avgVal

但抛出invalid object name SalesData。

不知道我做错了什么。

在聚合 SUM 上使用窗口化 AVG。

SELECT
    DATEADD(dd, DATEDIFF(dd, 0, saledate), 0)
    , SUM(something) AS Amount
    , ?? AS TRVal -- no idea what it is
    , AVG(SUM(something)) OVER () AS AvgVal
FROM MyTable -- or whatever
GROUP BY DATEDIFF(dd, 0, saledate)

SELECT saledate, Amount, TRVal, (SELECT avg(amount) FROM tableA) as AvgVal FROM tableA

或者

SELECT saledate, Amount, TRVal, avgVal FROM tableA
INNER JOIN (SELECT avg(amount) as AvgVal FROM tableA) x

编辑添加：

您必须替换SalesData为您正在查询的表的名称（您从示例中删除了该名称：

FROM(
-- whatever name you put here is the one you need in place of SalesData
)

编辑添加：

您的 FROM 子句很复杂，因此 MSSQL 2008 仅针对此类情况添加了 WITH 子句：

;WITH thisTable AS (
    -- put your FROM clause in here
)
SELECT /* list of fields */, (SELECT AVG(amount) FROM thisTable) as AvgVal
FROM thisTable

所以对你来说：

; WITH thisTable AS (

这是最直接的代码。如果太慢可以优化...

select saledate, amount, trval, (select avg(amount) from  yourtable) as AvgVal from yourtable;
