You are trying to assign $sth as a statement handle, but you can only do that when you prepare the statment first. A prepare call returns a statment handle,execute, then you bind your columns.

Here is the code form bind_columns on the DBI page of CPAN

  $dbh->{RaiseError} = 1; # do this, or check every call for errors
  $sth = $dbh->prepare(q{ SELECT region, sales FROM sales_by_region })
+;
  $sth->execute;
  my ($region, $sales);

  # Bind Perl variables to columns:
  $rv = $sth->bind_columns(\$region, \$sales);
  while ($sth->fetch) {
      print "$region: $sales\n";
  }

Notice how they first prepare,then execute,then bind, then fetch. Good luck!

Updated: I confused bind_params and bind_colunms. thanks gmax for pointing out my mistake.
