You can avoid the by using something like SELECT DISTINCT followed by the relevant fields. The approach will depend on the situation, and might not work for tables like these.

Quick question--how do you stop it from happening? What do you do if you want to collapse table B into table A?

Thank you so much for explaining this easily.. I appreciate your hardwork💜

Thank you for explaining why the duplicate were happening!

Make your own videos rather than copying and impersonating others. Shame on you for stealing videos from Udemy Website where the instructor has worked so hard to make the course. Wonder which country u come from. God bless the country and ur entire race. Have fun when u go to hell.
