Question

I have created a view on a local server, that gets it’s data from a linked server. On the linked I only have Read rights.

I am trying to improve the performance of my view, I tried to create the view WITH SCHEMABINDING, but are not allowed to use SCHEMABINDING on remote access. I tried reading up on Materialized Views, Yes I know it is a function in Oracle, but wanted to know if there is something similar in SQL server 2008 r2.

Any Ideas on how to increase the performance of my query?

CREATE VIEW [dbo].[vw_CustomerServiceLevel]

AS
SELECT *
FROM [10.205.0.70].Freightware.dbo.CustomerServiceLevelReportEOF RF
INNER JOIN [10.205.0.70].Freightware.dbo.CustomerServiceLevelReportDetail RD 
  ON (RD.HeaderGUID=RF.HeaderGUID)
INNER JOIN [10.205.0.70].Freightware.dbo.CustomerServiceLevelReportHeader RH 
  ON (RH.HeaderGUID=RD.HeaderGUID)
LEFT JOIN SDBPHASE2DW.dbo.DimDate dd
  ON CONVERT(VARCHAR(10), RH.StartDate, 103) = CONVERT(VARCHAR(10), dd.FullDate, 103)
LEFT JOIN SDBPHASE2DW.dbo.DimDate dd2
  ON CONVERT(VARCHAR(10), RH.EndDate, 103) = CONVERT(VARCHAR(10), dd2.FullDate, 103)

There are few things that you can do in order to optimize your code:

1. Do you need all returns columns?If not, select only the columns you
   need.
2. Do you need to convert the fields on which joins are made. It seems
   that they are the same, so you can remove the convert statements.
3. Do you need all the records?If not, just use a use defined function
   instead a view – it will be the same as your view, except you are
   able to pass to it some parameters that will cut the returned data.
