ONLINE = didn't ring a bell?

Just a FYI, dta is a bad tool to do performance tuning. This is what I do :

CREATE NONCLUSTERED INDEX [_dta_index_dClientCode_16_437576597__K7_K3_1] ON [dbo].[dClientCode]

(

[ClientGenericId] ASC,

[Code] ASC

)

INCLUDE ( [ClientCodeId]) WITH (SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = ON) ON [Data_Data]

Use online= off recommended,some indexes will not create with online option ON

It is comments like this that makes me shy away from this site. It is completely unnecessary. For those who care to know a more appropriate response, something this would have been more effective:

"Take a closer look at my previous comments in regard to ONLINE. If you still don't understand, then please provide very specific details about what you don't understand, and I'll try to help."

An online index (build) allows access / modification of the data while the index maintenance operations take place. It is (correct me if I'm wrong) an Enterprise feature. To create an online index, set the ONLINE flag to ONLINE = ON.

I cannot think of any disadvantages but the price of the Enterprise edition 😎

Yes, Enterprise Edition only

There are other caveates that will prevent an index from being bilt/rebuilt in an online fashion unless you have 2k14. If the table has blobs in them, then the clustered index cannot be built or rebuilt in an online fashion and the non-clustered indexes cannot be created or rebuilt if the index contains a blob in the INCLUDE clause.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

I agree but don't let the few drive you away from the many. There are lot's of good folks on this site and I've learned a lot from them.

Shifting gears a bit, the reason why I call this site "home" is because that type of thing actually happens a whole lot less here (especially in the last year) than what I've observed on other sites and the quality of the good answers and the fact that discussions about the answers are encouraged makes it all very worthwhile to me.

Heh... and no... I'm not an employee of this site or the parent company.

I have to agree with Jeff on this. We all make mistakes and respond in inappropriate ways at times, but for the most part we are a very professional group and have done a very good job of self policing ourselves and work very hard at trying to be a professional site for new comers and old residents.
