This piece of code works:

#! /usr/bin/perl

use strict;
use warnings;
use DBI ':sql_types';

my $dbh = DBI->connect('DBI:ODBC:driver=Microsoft Access-Treiber (*.md
+b);dbq=db1.mdb',user,pass);

my $col = 'Testcol';

my $statement = "INSERT INTO table (`$col`) VALUES(?)";

my $coltype = get_type($col,$dbh);
$coltype = 'SQL_'.$coltype;
my $sth = $dbh->prepare($statement);

for(2..1000){
  my $var = <STDIN>;
  chomp $var;
  no strict 'refs';
  $sth->bind_param(1,$var,&{"DBI::$coltype"});
  use strict 'refs';
  $sth->execute($var) or die $dbh->errstr();
}

sub get_type{
  my ($name,$dbh)  = @_;
  my ($sthcolinfo) = $dbh->column_info(undef,undef,undef,$name);
  my $hashref = $sthcolinfo->fetchrow_hashref();
  return $hashref->{TYPE_NAME};
}

But when I split the code in "script" and "module" it does not work.
I've tried this:

#! /usr/bin/perl

use strict;
use warnings;
use lib qw(.);
use DbiTest;
use DBI ':sql_types';


my $col = 'Testcol';
DbiTest->new($col);
[download]

module:

package DbiTest;

use strict;
use warnings;
use DBI ':sql_types';

sub new{
  my ($class,$col) = @_;
  my $dbh = DBI->connect('DBI:ODBC:driver=Microsoft Access-Treiber (*.
+mdb);dbq=db1.mdb',user,pass);

  my $statement = "INSERT INTO table (`$col`) VALUES(?)";

  my $coltype = get_type($col,$dbh);
  $coltype = 'SQL_'.$coltype;
  my $sth = $dbh->prepare($statement);

  for(2..1000){
    my $var = <STDIN>;
    chomp $var;
    no strict 'refs';
    $sth->bind_param(1,$var,&{"DBI::$coltype"});
    use strict 'refs';
    $sth->execute($var) or die $dbh->errstr();
  }
}

sub get_type{
  my ($name,$dbh)  = @_;
  my ($sthcolinfo) = $dbh->column_info(undef,undef,undef,$name);
  my $hashref = $sthcolinfo->fetchrow_hashref();
  return $hashref->{TYPE_NAME};
}

With that code the script dies with the following errormessage:

Usage: SQL_LONGVARCHAR() at DbiTest line 21
