Use placeholders (?) in your sql and extract the data from the parameters. 
if ( ($action eq "UPDATE") && ($empid =~ /\d+/)) {

  my @data=();
  my @fields = qw!lastname firstname title toc dob doh address city
                  region pcode country homephone ext notes repto!;
  for my $f (@fields)[
    push @data,$q->param($f) || '' ;
  }  
  push @data,$empid;
                  
  my $sql = qq!UPDATE "Employees" 
               SET "LastName"  = ?,
                   "FirstName" = ?,    
                   "Title"     = ?,          
                   "TitleOfCourtesy" = ?, 
                   "BirthDate" = ?,
                   "HireDate"  = ?,
