在视图中创建聚集/非聚集索引

Question

我有一个视图，它将值返回给表。这个过程需要很长时间...所以我觉得它更好的工作，如果去视图索引。任何人都可以指导我添加索引来查看。

ALTER View [dbo].[GetApplicationBudgetAndUtilized] 
as 

Select *, (convert(money,isnull(TotalBudget,0)) - convert(money,isnull(Utilized,0))) as [Left] from (
SELECT Distinct PM.PKID AS ProgramID, F.PKID as FundID, I.PKID as ProjectID,

索引视图有一定的limitations

在你的情况，我马上就可以看到一些阻滞剂

• SELECT *
• 派生表

因此，阅读这篇文章，看你有多远...

但是，你应该能够看的执行计划识别瓶颈，您可以添加索引到基地台
