Thanks for the video but I’m a little confused. I thought that merge joins rely on equijoins. Your presentation shows the contrary. Could you please clarify?
Hi, thanks for your tutorial... I am trying to apply what you said in my current task of my project and I'm having a dilemma. Please help me with this. I have 3 tables: table Title: - id - name table TitleRank: - id - name - title_id - rank table UserTitleRank -id -name -user_id I want to create FK at `UserTitleRank` to reference the `title_id` and `rank` at `TitleRank`. I have 2 choices: 1/ create composite FK `title_id` and `rank` at `UserTitleRank` table referencing `title_id` and `rank` of `TitleRank` 2/ create single FK `title_rank_id` referencing `id` of `TitleRank` Which one is better? What is the pros and cons of each and what is the implication and context I should take into account to select one over another? Thank you.

I feel much privileged to learn from you as a newbie sql learner. I have only a simple enquiry. I was still confused between primary, foreign and composite key. I hope if you can teach me their differences in simple terms. Thanks a lot.
