with Perl and *using placeholders and bind values*, the application
developer has not to worry about this. So, usually I don't check the
values in my applications (e.g. if only values between 1 and 5 are
allowed and under normal circumstances only these are possible), it's the
task of the database (check constraint).
Ciao
