Perhaps people could clarify a couple of things:
(1) There is no semantic difference between the two queries in the Guide example quoted above by Patrick. Why does the guide warn: "In this case, if this flag is set counters and SELECT COUNT may deliver wrong results"? Is this just a bad example?
(2) Is this warning just a general warning to people who don't understand much SQL, or does use of this flag mean that HANA will sometimes disregard semantic differences and rewrite the SQL regardless leading to a different (i.e. incorrect) result?
