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...

Maybe this will help (?)

use tempdb;
go
declare @SomeDate DATE = '2019-05-31';
SELECT @SomeDate AS TextDate,
 DATEADD(day,1,CAST(@SomeDate AS DATE)) AS NextDay,
 YEAR(CAST(@SomeDate AS DATE)) AS SomeYear,
 CONCAT(CONCAT(DATENAME(month,CAST(@SomeDate AS DATE)),' '), YEAR(CAST(@SomeDate AS DATE)))...

30m different from what? the previous record? Use LAG() for that. Then...

You need Jeff Moden's DelimitedSplit8K function to do that.

Here's how to use it... (but do read the article - it's really good!)

CREATE TABLE SomeData(emailaddr VARCHAR(20), Repeating...

Or use CROSS APPLY... but the above is probably easier.

SELECT p.Id
  , p.Surname
  , p.Bed
  , p.OpDate
  , patientData.SampleDate
  , patientData.BP
  , patientData.Temp
FROM Patient p
CROSS APPLY (SELECT TOP 1 ID, BP, Temp, SampleDate
   FROM...

What if you used ROWNUMBER() OVER (PARTITION BY StudentID) and then pivoted on that?

Maybe read Jeff Moden's article on pivoting in T-SQL. Otherwise, could you post a CREATE TABLE script and an INSERT script to show some sample data?

Sounds like you need a...

If you have a table for the times

CREATE TABLE HoursList (

HourNumber TINYINT PRIMARY KEY

INSERT INTO HoursList(0, '12 AM-1 AM'),(1,'1 AM -...
