Grant, I can see a case such as the example in BOL (ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/udb9/html/0208b259-7129-4d9f-9204-8445a8119116.htm) where due to the recursive nature of the data a CROSS APPLY will be efficient.  However, do...

I have the HIGHEST regards for Itzik's skills with TSQL and enjoy his writings and even use a number of his examples in my classes/presentations.  This book, however, is NOT...

1) I would be leery of attempting to build a production system using mirroring if you are a sql server newbie.  WAY too many opportunities to fail there, and you...

1) Confused.  In your original post you stated there was no line in the sproc that did CREATE INDEX, yet in the last post you made you gave a temp...

One of my favorites is Beginning Transact SQL ... by wrox press. 

Agree with the others here that you should store data in the appropriate datatype, for a number of reasons.  One thing you should do also is to pick the CORRECT...

Nope... you made an unqualified statement with no conditions.  And no one would force such an index as you have because everyone knows the bookmarks will kill any hope of...

Yes, really.  Your fabricated example uses a covering index and thus has no need to touch the base table.  Change your select to this:

 SELECT SomeID, SomeString, somedate

   FROM dbo.IndexTest

  WHERE...

1) Your "realistic assumptions" still have a fundamental flaw.  Many (most in my experience and also from students in the classes I teach) Microsoft shops don't have even a SINGLE...

Rudy, you are likely doing things backwards I think, especially in this case where there may well have been NO tuning/indexing done in the first place (given that a .NET...

Yeah - there are definitely some sharp guys out there consulting that are unfortunately not very good in the 'mentor' roll.  That is a pretty good performance gain (14 to...

New to this thread.  The single most USEFUL thing you can do is to hire an expert to give your databases, servers and code a performance review.  First, this will...

1) For a dynamic search on large tables you are probably best using dynamic sql, since the cost of the compile is often MUCH, MUCH less than the cost of...
