If you're trying add these values to a CTE, wouldn't you use UNION? Probably in a second CTE.

There was absolute agreement on the OUTER JOIN being an issue. The question was, did placing filters on the INNER JOIN make a difference? Several people anecdotally believe(d) so (myself...

Generally, I've just passed all the fields back to the proc and updated them. Depending the app & the business needs, it usually doesn't matter if FieldX is updated from...

The time differences on those are pretty trivial. The same number of scans and the same number of reads usually tell you most of what you need to know.

You'll have to store the symbol and it's associated currency in a table in order to select on it. Otherwise you could create an enormous CASE statement, but the first...

That sure sounds like homework.

Not for OUTER JOINS though. With...

Hi Grant,

what makes you sure this time that it does not make a difference?

Did you get this information from Microsoft ?

I am pretty sure that I had examples...

Well, eliminating all the excess JOINS does improve performance threefold in this example, so I think you can reasonably expect the something similar with larger data sets.

Because of the OR...

I've got nothing. The examples I thought I had, I can't find.

My heartfelt apologies for putting out bad information. For an INNER JOIN, it really makes no difference in terms...

I probably won't have the example, assuming I can find it, until tomorrow. I'm looking though.

I did find this in the BOL

I'm going to start digging, but I've had instances where moving filtration from the WHERE clause to the ON clause does change the execution plan. I don't have the example...
