我有一个查询，结果如下所示
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
我想要像这样的平均金额
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

我尝试添加
(SELECT avg(TotalValue) FROM SalesData) as avgVal
但抛出 无效的对象名称 SalesData。
不确定我做错了什么。
最佳答案
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)
