Sorry for the silly question, but if you do everything in a stored procedure, what's the difference? Maybe you have a CTE with two pivots in it, and then at...

Not totally sure I understand. Can you create two pivots and then join the results on the shared columns?

Something like this... I'm not sure my query is 100 percent correct, because I'm not sure what D_ID and E_ID mean.

SELECT D_ID
 , E_ID
 , Salary
 , LAG(Salary, 1) OVER...

Can you get the data before it's pivoted, so there are dates in there instead of quarters? Normally in a tabular model, your fact table will have a date or...

There's a new cardinality estimator in SQL 2016.  Force your query to use the old one. See: https://stackoverflow.com/questions/47215135/facing-performance-issues-in-sql-server-2016-after-migration

Sounds like a job for CROSS APPLY.

SELECT e.EquipmentName
 , lw.WarrDescription
 , lw.StartDate
 , lw.EndDate
FROM Equipment e
CROSS APPLY (SELECT TOP 1 StartDate, EndDate, WarrDescription

I did the Prerequisite/Co-requisite course thing a long time ago, and asked about it there. So if you look for it, Jeff Moden and someone else answered and came up...

I formatted it.. I got lost in the CTE stuff because I wasn't following all the logic. I would definitely comment the chunks just to make it easier for other...

In the absence of better code, this is what I came up with.  I'm assuming you have a table of holidays like #Holidays table. Then you just check for the...

Shouldn't your WHERE clause be like this?

WHERE SoftwareTitle NOT IN ( SELECT <fieldname> FROM #TempTable)

You can't match a single column (SoftwareTitle) to all the columns (*) in #TempTable

Something like this?

SELECT *
FROM CustInfo ci
WHERE DateCreated IN ( SELECT DateCreated
      FROM CustInfo 
      WHERE EntryType = 'Expired')
AND ci.EntryType != 'Expired';

(Sorry, I renamed your table to CustInfo).

Without CREATE TABLE and INSERT scripts (sample data), there's no way to answer your question.

What does "didn't work" mean?

I think having a slide so attendees can decide whether the presentation will benefit them is a good idea. I think it would be a good idea to include that...
