Your explanations are on point. My professor is pretty much like “Figure it out yourself, look at the PPT” SMH.

[@MrTekniqs]

Most of my college education right here. “Hey guys we’re going to learn Java. Here’s a piece of paper with some code. I’m a math teacher good luck.”

[@MrBicholino]

[@niru216]

Thanks! joins were pain until I found you

[@mezomezo8718]

I have a question which making me not getting this whole self join thing why couldn't we refer our join condition on table A customer ID =table 2 manager ID why did we have to refer to the foreign key of the first table instead of the primary key.your answer is greatly appreciated.

[@edwardtattersfield3033]

Bro, nice vid. ONE QUESTION! What keyboard shortcut are you using to track to the beginning of a word? As you have done it makes more sense for me to type the column and THEN the table even though sql syntax requires this info in the opposite order. The shortcut would make it easier - i cant find it online.🙏

[@justinprice1929]

He's probably using Ctrl+'any-arrow-key' for PC, and it would be Command+'any-arrow-key' for Mac.

[@methanesulfonic]

I'm pretty sure my teacher will somehow over-complicate this course if they ever teach this lol.

[@riasingh11]

[@user-gh1tk2dc3l]

Thanks Bro

[@muratemredemircioglu2897]

i am a beginner... We have to create employee ids such a way that when we write the code, it has to point the correct way right? I mean what if we made Mr. Squidward's employee id 6?

[@CodeWithDF]

u are great but can u do tut for website full course

[@mehavenothing7078]

i want to ask a question, why after we use the inner join, on a.supervisor_id = b.employees_id; the sandy name will repeated a few times, i still didnt get why

[@user-of9pw6ql4m]

Because she is a supervisor of multiple people. You're looking at each row of the left table and see who is the supervisor for each employee in that table which is Sandy except for Sandy herself. Her supervisor is Crabs.
