Question

我在SQL中有以下查询以求和和平均值：

USE DBSTG_INT
GO

select distinct 
sum(a.EventoPrecioReg) as PrecioRegular,
sum(a.EventoPrecioVta) as PrecioVenta,
AVG(VTA_IUnidades) as Unidades,
SUM((a.EventoPrecioVta - a.EventoPrecioReg) * (AVG(VTA_IUnidades))) as Inversion
from EventoPrecioDeta a WITH (NOLOCK)

当我执行它时，它显示以下问题：

第15层，州1，第8行的消息130
无法对包含聚合或子查询的表达式执行聚合功能。

我做错了什么以及如何解决？

Answer 1

select distinct在这种情况下没有意义。您的问题是嵌套聚合。也许您打算：

select sum(a.EventoPrecioReg) as PrecioRegular,
       sum(a.EventoPrecioVta) as PrecioVenta,
       AVG(VTA_IUnidades) as Unidades,
       SUM(a.EventoPrecioVta - a.EventoPrecioReg) * AVG(VTA_IUnidades) as Inversion
from EventoPrecioDeta a ;

Answer 2

像下面一样尝试

select  
sum(a.EventoPrecioReg) as PrecioRegular,
sum(a.EventoPrecioVta) as PrecioVenta,
AVG(VTA_IUnidades) as Unidades,
SUM(a.EventoPrecioVta - a.EventoPrecioReg) * AVG(VTA_IUnidades) as Inversion
from EventoPrecioDeta a

解决SUM和AVG，无法对包含聚集或子查询的表达式执行聚集功能
