Actually, placeholders *do* handle the null parameter. Constructing the update statement can do the rest...

my @fields = qw(name phone city country); my $SQL = "update table set " . join(", ", map { "$_=?" } @fields) . "where ...."; my $ST=$DB->prepare($SQL); while (...) { my @values = (.....); $ST->execute(@values); }
