mysql update table how to

VC has asked for the wisdom of the Perl Monks concerning the following question:

I want to update all Disabled in mysql table, but I am only being Abel to update just one? HELP

    $username = DB::trim (param ("Username"));
    $password = DB::trim (param ("Password"));

    $dbh = DB::connect();
    $sth = $dbh->prepare ("SELECT * FROM EmployerJobs WHERE Username =
+ ? AND Password = ?");
    $sth->execute($username, $password);
    
    while (my $row = $sth->fetchrow_hashref ())
    {
          $ID = $row->{ID};
          
      if ($userid eq $row->{USERID}) {
        
        $DISABLE = $row->{Disabled};
        
        if (param("Disabled") eq "Yes") {
            $DISABLE = "Yes";            
            param (-name => "Disabled", -value => $DISABLE);
            param (-name => "ID", -value => $ID);
            
            $tbl_info = DB::TableInfo->get ($dbh, "EmployerJobs");
             $tbl_info->update_record ($dbh, "ID");

        }elsif (param("Disabled") eq "No") {
                $DISABLE = "No";
                param (-name => "Disabled", -value => $DISABLE);
                param (-name => "ID", -value => $ID);
                
                $tbl_info = DB::TableInfo->get ($dbh, "EmployerJobs");
                 $tbl_info->update_record ($dbh, "ID");

        }else
        {
                param (-name => "Disabled", -value => "No");
                param (-name => "ID", -value => $ID);
                
                $tbl_info = DB::TableInfo->get ($dbh, "EmployerJobs");
                 $tbl_info->update_record ($dbh, "ID");
        }
        
      }
    }
    $sth->finish ();

`if ($userid eq $row->{USERID}) {` Clearly, this restricts which rows will be processed. If you don't want such a restriction then don't use it.	[reply] [d/l]

near '<> ' what is near <>? Right before it is an equals sign. So you are asing for "Disabled equals-to not-equals-a-value". so which is it, equals or not-equals that you want?	[reply]
