However given that java's == and SQL = and java's && and SQL AND have
different semantics in some cases are you sure you want to teach them
something that's actually incorrect in any case. Saying "same as java" is
not any help to your students when they run into cases where string or
date comparison with == is not the same as in java or foo.a=bar.a && <some
condition containing 1/foo.a> errors with a division by 0 when there are
no 0 values in bar.a.
