      Maybe I'm obtuse, but why is there an AS Rating? Just remove that bit.

      I was just looking at that and couldn't see where it was being used either.

        UPDATE bathrooms
           SET bathrooms.Rating = (SELECT AVG(Reviews.Rating)
                           FROM Reviews
                          WHERE Reviews.bathroom_ID = bathrooms.id)

          Is this an intentional fast lookup cache table? Because this violated the database integrity. Just a thought while I'm looking for an answer.

          The bathroom table is the main table for lookups so yes and the server runs on SSDs with 4gb of ram and two 3.2ghz vCores

            Boom, sweet! You can use the ellipses on the individual post to make it as the correct answer, too 🙂

              Are you going to do a scheduled batch run on this (tee hee, batch run) like at night to update the reviews?

                I was going to do that or pass the ID of the bathroom then fire it on a review or bathroom submission.

                  You could use a database trigger for that, too.

                    If you expect this product to explode you might want to consider a NoSQL database now. Easy to switch now, hard later. MySQL scales pretty big, but things like MongoDB and Cassandra go so much bigger. Worth thinking about now before you are more or less locked in.

                          Knowing you, intentional.
