                This is apparently non-standard. The standard only allows ALL and ANY for <equals operator>, <not equals operator>, <less than operator>, <greater than operator>, <less than or equals operator>, <greater than or equals operator>.

                Don't know why, actually. Allowing BETWEEN is perfectly logical, I'd say.

                Also, the equivalent of

                <subquery> BETWEEN <val1> AND <val2>

                is:

                val1 <= <subquery> AND val2 >= <subquery>

                which is not optimized (subquery is executed twice). And it's horribly verbose.
