Do you use RIGHT JOINs? I myself rarely use a RIGHT JOIN, I think in the last 17 years or so I have only used a RIGHT JOIN once or twice. I think that RIGHT JOINs confuse people who are new to databases, everything that you can do with a RIGHT JOIN, you can also do with a LEFT JOIN, you just have to flip the query around
So why did I use a RIGHT JOIN then?
Don’t be lazy; switch out those right joins. The trick is that for every RIGHT JOIN statement, there is an equivalent statement which does not use RIGHT JOIN. The percentage of the time that you might benefit from RIGHT JOIN is so low that the fixed costs of mentally processing what’s going on tend to overwhelm the slight benefit of that style of join.
