comparisons return false) false If you think these results look a lot like what we saw with IN(), you’re right: with the ‘=’ operator, ANY is the same as IN. In the same way, “<> ALL” is equivalent to NOT IN Under the “right” circumstances, this can lead to wrong results with expressions of the type “NOT A = ANY( … )”.
