Hello Monks,

I have a placeholder problem (which is most likey something silly) where the "?" is being assigned a literal string instead of the column name. A code extract is below (@reults is a list of caseids): 

use strict;
use Template;
use CGI;
use CGI::Session ( '-ip_match' );
use DBI;
use Data::Dumper;
use Sphinx::Search;
require "lib/class.pm";
my $cgi = new CGI;
my $dbh = new_dbh();
my $sph = sphinx_conn();
my $query = $cgi->param('search_index');
my $index = "cases";
my $field = $cgi->param('field');
my $col = "case_header";
my $header; 

....

foreach my $x(@results){
    my $sth = $dbh->prepare("SELECT ?,status,DATE_FORMAT(added_date, \
+"%d/%m/%Y\")  from cases where caseid = ?");    
    $sth->execute($col,$x);
        while (my @row = $sth->fetchrow_array()) {
        my $docs = \@row;
        my $bar = \%options;
        my $excerpts = $sph->BuildExcerpts($docs,$index, $query, $bar)
+;
        my @deref_excerpts = @$excerpts;
        unshift (@deref_excerpts,$x);
        push (@send_to_template,\@deref_excerpts);
         }
}

The result is "case_header" for all results in the case_header column instead of the actual results. The other columns display the correct result. If I use $col in the SQL query instead of the firs "?" I get the expected results. Can anyone spot what I have done!?
