In addition to everything Grant said, and he literally wrote the book on execution plans:

I'd also point out that the ORDER BY dufp.FeatureName will cause a sort to...

The key here is the types of queries, not simply should I throw an index on. Columnstore indexes are meant for analytical, aggregation & large scan types of queries. That's...

I assume you've tried and the error explained that your column names are not there. You can't create a view based on ad hoc queries because the view definition needs...

All the cost is located here: [Excel_DK].[dbo].[Excel_DK].[pk_ID] [DUFP]

The predicate is: [Excel_DK].[dbo].[Excel_DK].[PartNumber] as [DUFP].[PartNumber]=[@partNumber]

Probably need an index on that with some INCLUDE for the other returned columns.

Also, you have three different...

Then, ever so strongly, I recommend you pursue other approaches. Partitioning almost never succeeds in improving performance. By almost never, I mean, probably, a 99% failure rate. It's purpose is...

So, have you and the business worked out your Recovery Time Objective and Recovery Point Objective? If not, go do that first. If so, test this method on a restore....

Define a role. Put the users in that role. Then GRANT SELECT to the role for the schema in question. You can also grant additional functionality to the role....

One possibility would be to snapshot a...

Yeah, I'm not at all surprised that it installed. I just doubt it did anything during that install. It found higher versions or the same versions on all the stuff...

Way back in the day, Brad Macgeehee did a bunch of testing around reorganize and rebuild. What he found is that the majority of the time, reorganize almost didn't do...

This sums it up. You're taking a risk. It'll probably be OK. But it might not be.

In terms of function, yes. They're identical. In terms of supported hardware, etc., No, they're not identical. The developer version should function perfectly as a test system in non-production environments....

Look at the execution plan. It's possible that your data crossed a threshold that changed the row counts. Maybe it used to do an index seek and now it's doing...

People do this all the time. It's relatively standard. The only real issue with it is ensuring that your network doesn't become the bottleneck instead of I/O. That's just about...

Yep. What John says. The cumulative update is just that, an accumulation of updates, security or not, up to that point. Can you add a newer security update created after...
