我正在尝试在视图上放置索引，但一直遇到出现错误的问题

因为视图的选择列表包含聚合函数或分组列的结果表达式。考虑从选择列表中删除聚合函数或分组列的结果表达式。

代码：

USE [DB]
GO

/****** Object:  View [dbo].[MonthlyView]    Script Date: 03/17/2014 15:19:10 ******/
SET ANSI_NULLS ON
GO

--Set the options to support indexed views.
SET NUMERIC_ROUNDABORT OFF;
SET ANSI_PADDING, ANSI_WARNINGS, CONCAT_NULL_YIELDS_NULL, ARITHABORT,
    QUOTED_IDENTIFIER, ANSI_NULLS ON;
GO


SET QUOTED_IDENTIFIER ON
GO

ALTER VIEW [dbo].[MonthlyView2]
WITH SCHEMABINDING 
AS
SELECT                
                      ISNULL(SUM(I.RSQty),0) AS RSQty,
                      ISNULL(SUM(I.COGQty),0) AS COGQty,
                      ISNULL(SUM(I.DSQty),0) AS DSQty, 
                      ISNULL(SUM(I.LossQty),0) AS LossQty,
                      ISNULL(SUM(I.AbuseQty),0) AS AbuseQty,
                      ISNULL(SUM(I.InventoryChgQty),0) AS InventoryChgQty,
                      ISNULL(SUM(I.RSRev),0) AS RSRev,
                      ISNULL(SUM(I.COGRev),0) AS COGRev,
                      ISNULL(SUM(I.DSRev),0) AS DSRev,
                      ISNULL(SUM(I.LossRev),0) AS LossRev,
                      ISNULL( SUM(I.AbuseRev),0) AS AbuseRev,
                      ISNULL(SUM(I.InventoryChgRev),0) AS InventoryChgRev, 
                      ISNULL(SUM(I.EnergyChg + I.EnvironChg + I.HandlingChg + I.OtherChg + I.Discount + I.StopMin),0) AS Surcharge,
                      COUNT_BIG(*) as cbig,
                      M.MonthId, PeriodEnd, id, Sku
FROM         dbo.ItemRev AS I INNER JOIN
                      dbo.Weeks AS w ON I.WeekId = w.WeekId INNER JOIN
                      dbo.Month AS M ON M.MonthId = w.MonthId
GROUP BY  M.MonthId, PeriodEnd, id, Sku


GO

CREATE UNIQUE CLUSTERED INDEX IX_vMonthly on [dbo].[MonthlyView2]
(
    [ID] asc,
    [PeriodEnd] asc,
    [MonthId] asc,
    [SKU] asc
)

我遇到了这个错误，发现它可以使用

sum(isnull(myfieldname, 0))

代替

isnull(sum(myfieldname), 0)

请注意，这些含义存在细微差别，因为第一个会将空值视为 0，但如果任何一个为空，第二个将给出零结果。

文档列出了大量限制。你正在做的事情是不允许的。

一个简单的解决方法是在不执行不允许操作的视图上创建索引，并将其包装在另一个应用“标量计算”（ISNULL在您的代码中）的视图中。
