indexed-view

I have a view which already has SchemaBinding applied AND it has a UNIQUE CLUSTERED index. Now, i'm trying to add a second index, which is a SPATIAL index ... and I get the following error message:- and here's the a piccy of the schema.... Can someone help, please? Pure.Krome FFS - I found my answer . Spatial Indexes cannot be specified on indexed views. The error message is incorrect / misleading.

I have an indexed view that I need to specify the noexpand hint for in order for it to perform reasonably. Unfortunately as seen with regard to modifying the Linq to SQL generated T-SQL query from the NOLOCK hint it appears that there is no easy way to take advantage of these hints directly or is there? My thought is that it would make sense to allow customization of this stuff through the use of attributes or declaratively through the dbml. Also since Linq to SQL seems to only work targeting SQL Server it only makes sense that we are also able to leverage these advanced features (if they

I want to create the following indexed view: CREATE VIEW [Cic].[vwMarker] WITH SCHEMABINDING AS Select SubId, marker.EquipmentID, marker.ReadTime, marker.CdsLotOpside, marker.CdsLotBackside, marker.CdteLotOpside, marker.CdTeLotBackside From dbo.Marker Where dbo.Marker.ReadTime >= Convert(dateTime,'10/5/2011',120) GO CREATE UNIQUE CLUSTERED INDEX IX_vwMarker_ReadTime_EquipmentID ON Cic.vwMarker (ReadTime, EquipmentID); This works fine. However, what I would really like to do is to only include rows in this view that are two days old or newer, as of the current date/time the view is queried. I

My Requirement: I have this straight forward requirement of listing names of people in alphabetical order in a Indexed table view with index titles being the starting letter of alphabets (additionally a search icon at the top and # to display misc values which start with a number and other special characters). What I have done so far: 1. I am using core data for storage and "last_name" is modelled as a String property in the Contacts entity 2.I am using a NSFetchedResultsController to display the sorted indexed table view. Issues accomplishing my requirement: 1. First up, I couldn't get the

I have a simple Indexed View. When I query against it, it's pretty slow. First I show you the schema's and indexes. Then the simple queries. Finally a query plan screnie. Update: Proof of Solution at the bottom of this post. Schema This is what it looks like :- CREATE view [dbo].[PostsCleanSubjectView] with SCHEMABINDING AS SELECT PostId, PostTypeId, [dbo].[ToUriCleanText]([Subject]) AS CleanedSubject FROM [dbo].[Posts] My udf ToUriCleanText just replaces various characters with an empty character. Eg. replaces all '#' chars with ''. Then i've added two indexes on this :- Indexes Primary Key

I'm trying to optimize a query which uses a view in MySQL 5.1. It seems that even if I select 1 column from the view it always does a full table scan. Is that the expected behaviour? The view is just a SELECT "All Columns From These Tables - NOT *" for the tables I have specified in the first query below. This is my explain output from when i select the indexed column PromotionID from the query which makes up the view. As you can see it is vastly different from the output on the view. EXPLAIN SELECT pb.PromotionID FROM PromotionBase pb INNER JOIN PromotionCart pct ON pb.PromotionID = pct
