It's fun when these change between versions too. At work we recently upgraded a bunch of servers from MySQL 5.7 to 8.0 (yeah I know, basically last second) and missed a stored procedure that was using "rows" unquoted. Fine in 5.7; reserved as of 8.0.2. I also find their documentation on this sort of thing to be far too sprawled to be easily accessible, makes it quite hard to prepare for this sort of thing if you're not particularly expert when it comes to database administration.
