If anyone was looking for the new data in this video:

Insert into EmployeeDemographics VALUES
(1011, 'Ryan', 'Howard', 26, 'Male'),
(NULL, 'Holly', 'Flax', NULL, 'Male'),
(1013, 'Darryl', 'Philbin', NULL, 'Male')

Insert into EmployeeSalary VALUES
(1010, NULL, 47000),
(NULL, 'Salesman', 43000)

I cannot thank you enough for this simple explanation. I nearly exhausted my resources for JOINs and nobody ever explained well enough for me to understand.

@AlexTheAnalyst, I want to take the time and thank you for making and sharing these videos. I am pursuing a degree in Information Systems, and I took a class in SQL, but your tutorial videos are easier to comprehend. I learned more in your short videos than I did in my class. You are amazing!!!!

I’m so glad you explained what was the left and right table. I tried to Google and really couldn’t understand anyone’s explanation. But you made it so simple that I want to laugh at myself for not realizing the diff between left and right before. Thank you Alex
