Personally I find something like this easier to read and definatly less error prone, the field names are only in one place: 
my @fields = qw/cat itemid price des longdes size o1n o1o o2n 
                o2o o3n o3o c1n c1v c2n c2v c3n c3v small large/;

my $sql = sprintf 'INSERT INTO items (%s) VALUES (%s)',
                join(',', @fields), join(',', (?) x @fields);
              
$dbh->do($sql, undef, map scalar param($_), @fields);
