I am working in sqlserver 2008 R2
I have an interesting question. My question is does index Reorganize and rebuild everyday increases the DB performance? Which is good weekly...
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
Need to UNPIVOT? Why not CROSS APPLY VALUES instead?[/url]
Since random numbers are too important to be left to chance, let's generate some![/url]

I have a general question concerning joins. Below is a table scenario that I would like advice on -
SELECT *
FROM TABLE_A T0
INNER JOIN TABLE_B T1 ON T1.[Some_Column] =...

Isn't this what PARSENAME is for?

SELECT *

Nasty CROSS JOIN that.
Perhaps one of these instead?
CREATE TABLE #NumVals (ID INT, MatrixCat VARCHAR(100), MatrixVal VARCHAR(100));
INSERT INTO #NumVals (ID, MatrixCat, MatrixVal) VALUES
(1, '# Ready To...

Quite interesting.
This illustrates the problem.
CREATE VIEW dbo.Test
WITH SCHEMABINDING
AS
SELECT
RecordLastChangedDateKey=20150204,
x=CAST('20150204' AS DATE) ;
GO
CREATE UNIQUE CLUSTERED INDEX IDX_t1 ON dbo.Test (RecordLastChangedDateKey, x);
GO
SELECT *
FROM dbo.Test;
GO
DROP VIEW dbo.Test;
Perhaps this solves it?
CREATE VIEW dbo.Test
WITH SCHEMABINDING
AS
SELECT...

If this is Romley's division (I'm sorry but I did not recognize it as such, which of course doesn't mean that it is not), Peter Larsson proposes a faster method...
