I have a simple script which converts access tables to XML.

use XML::Simple;
use Data::Dumper;
use DBI;

my $config = XMLin('c:\website\config.xml', forcearray => qr/table/ ) 
  or die ("unable to open config file");

my ($access_database) = @{$config->{database}};

my ($results_directory) = @{$config->{results_directory}};

my $dsn = "driver=Microsoft Access Driver (*.mdb);dbq=$access_database
+";

my $driver = "dbi:ODBC:$dsn";
my $username = '';
my $password = '';
my $dbopt = { PrintError => 0,
              RaiseError => 0 };

open (LOG,'>c:\website\log.txt') or die "log $!";

my $dbh = DBI->connect($driver, $username, $password, $dbopt)
  or die "Error connecting: $DBI::errstr";
for $extract (@{$config->{extract}}) {

  my $results_file = $extract->{file};
          
  my @results;
  my $ref;
        
  for $table (@{$extract->{table}}) {   
    
    my $sql = "SELECT * FROM $table";

    my $sth = $dbh->prepare($sql) 
      or die "Unable to prepare ($sql): ", $dbh->errstr;;

    $sth->execute
      or die "Unable to execute ($sql): ", $sth->errstr;
                
    $ref->{$table} = $sth->fetchall_arrayref({});
  }
                
  my $results = XMLout($ref,rootname=>'root', noattr=>1);       

  print LOG Dumper $ref;
  print LOG $results;
  print LOG "\n\n";

  local *RESXML;

  open (RESXML, ">$results_directory\\$results_file") or
    die ("Unable to open results file $results_directory\\$results_fil
+e: $!");
                
  print RESXML $results;
}

I can't hand out the database, but I can tell you it's pretty simple with a few numeric, date, memo, and text fields.

The problem is that some result sets are empty, even though the database table is populated.

So, I did a little test. I wrote a small script which did nothing more than select * from accommodation. That didn't work. I got no rows in my results set at all.

If I did select count(*) from accommodation, I got the count of the rows.</p?

If I did select <field> from accommodation, that worked fine.

I am more stumped that stumpy the stumpy dwarf.
