   expr BETWEEN min AND max
If expr is greater than or equal to min and expr is
less than or equal to max, BETWEEN returns 1,
otherwise it returns 0.  This is equivalent to the expression
(min <= expr AND expr <= max) if all the arguments are of the
same type. Otherwise type conversion takes place according to the rules
described at the beginning of this section, but applied to all the three
arguments. Note: Before MySQL
4.0.5, arguments were converted to the type of expr instead.
