      imagine holding match Box toy on your LEFT and a match A drink on your RIGHT
      LEFT join pulls matching B records and all of A while
      RIGHT join pulls matching A records and all of B

I was completely lost when I was reading about the Join process, and most videos usually don't help as much. This video was not only informational but also very fun to watch. It was kind of like watching a movie. Once again, thank you to everyone who contributed in this. Subscribed.

    • @DrShpilev
      @DrShpilev 5 ปีที่แล้ว +6

      Don't worry. The SQL will also be encapsulated by a layer or AI. I mean... sure... the AI will probably also plot to vacate all of Earths atmosphere or something, but at least you wouldn't actually have to write the SQL yourself anymore.

    By far you've explained joins as best I've seen on YT. Using inner join as the standard and left, right, and full as different tools it helps add context for why you would utilize the joins. So many times people try to explain this stuff completely theoretically, and does my head in. I enjoy the quirkiness too

    literally the most relateable video ive seen on joins. ive been doing databases for about 10 years never had to use joins until recently, i could just write code and extract with seperate queries. or use aliases and take values and insert a function. sometimes you need to extract one value from one sql without furthersteps. thank you so much im not even finished the video and feel like i can go back and conquer the world lol

  • @lalligood
    @lalligood 5 ปีที่แล้ว +4

    It's worth noting that PostgreSQL also has a USING clause for joins, which can be used in place of the ON clause when--and only when--the column(s) being joined on in both tables have the same name. So using the example in the video, "ON b.base_id = m.base_id" could be replaced with "USING (base_id)". And yes, that syntax would work for all 4 types of joins.

    • @jvsnyc
      @jvsnyc 5 ปีที่แล้ว

      Yup. Unfortunately, there are a lot of DBMS's that do not USE USING, so it wouldn't work in code trying to be portable across DBMS choices.
