I don't like SQL Server for example, I need to get a select result and generate script to insert based in values for the query to put in other table or database its impossible without payable tools. In MySQL its easier.

As someone that has been writing code for 40 years I totally agree with your initial premise. If you are writing the SQL you need to understand how it operates and the costs/tradeoffs you may be making. Your video content was very well organized and presented.

I'm running SQL server 2017 and I don't get any results back when I run the query for 2.6. Also, if I compare the estimated execution plans for both queries I don't see an entry for "Top" with the query using "WHERE NOT EXISTS". For the first issue, I would guess that I could delete all records from the CourseEnrollments table where the CourseOfferingId is 56637 or 58317. With the second issue, I can only guess that my version of SQL is coming up with a different execution plan, and I have no control over that? UPDATE: Looking at the video again, I saw that there is an Index Seek on the CourseEnrollments table, so it looks like the database backup is missing that. I added the following index and my execution plan now matches what is shown in the video:
USE [Students]
GO
CREATE NONCLUSTERED INDEX IX_CourseEnrollments_CourseOfferingID
ON [dbo].[CourseEnrollments] ([CourseOfferingId])
GO

Another codecamp course that doesn't indicate the version in the title or the description, which probably means it is an OLD version of SQL Server.

When he is comparing execution plans, why does he only look at estimated execution plans?? There can be a lot of useful information in the actual execution plan, which contains the actual values (actual number of rows read, etc.), which can differ a lot from the estimated values .... and such differences can be key in figuring out why a query runs slowly.

If possible, run multiple queries at the same time. Results will be easier to compare when you have several execution plans in sight and can just hover a mouse over them for comparison.

Hey! this is Rajan Arora. Thank you so much Beau for posting my tutorial. I hope this will help all the viewers to tune their SQL Statements in MS SQL Server. I hope we have more collaboration like this in the future!
