This operation converts Perl's characters, which is what your program operates on, to octets that can be used by the outside wor...

Thus you would store an internal value indicating whether the value is true or false or null, i.e. in your example >0 for true, <0 for false and ==0 for null, and t...
PreparedStatement IN clause alternatives?
