问题 I’ve just started looking into optimizing my queries through indexes because SQL data is growing large and fast. I looked at how the optimizer is processing my query through the Execution plan in SSMS and noticed that a Sort operator is being used. I’ve heard that a Sort operator indicates a bad design in the query since the sort can be made prematurely through an index. So here is an example table and data similar to what I’m doing: IF OBJECT_ID('dbo.Store') IS NOT NULL DROP TABLE dbo.[Store

问题 I am trying to view SQL generated by Linq to SQL in the SQL Server Profiler (2005). I can see the sql sent to the server from anything except for linq to sql. I'm betting that I need to change event selections for the trace, but not sure what else to select. I am currently only selecting this: SQL:StmtCompleted - TextData & SPID I don't want to use data context logging nor the SQL Debug Visualizer. I need to use the profiler. Why can I not see the LINQ to SQL queries? Thanks. EDIT I added SQL

MAIN_REPORT runs a query that returns a set of Areas, with multiple TagNames per area: AREA Tagname ---------- A1 T1 A1 T2 A2 T3 A3 T4 If you select one of the Area cells, it opens SUB_REPORT and passes a parameter to @ParentTagNames using Join(Parameters!ResultsOfSearch.Value,",") . ResultsOfSearch is equal to the Tagname column above (haven't yet figured out how to

问题 I'm using entity framework 4 for the first time in an ASP.net application.

问题 I was wondering if you guys could help me get to the bottom of a weird problem I have recently had on SQL Server. I have a stored procedure (lets call SPold ) which is reasonably large with a lot of calculations (can't possibly do this in app as info for around 6000 users needs to come back in a one-er (I reduce this to 1000 based on Surname)). The stored procedure usually executes in a couple of seconds, and is called once every couple of minutes. Now this morning, the stored procedure was
