First guess at a quick glance: This is a scoping problem, try 

 #---- snip ---
 my @allrows;
 my @UDNumber;
 while (my @row1 = $sth ->fetchrow_array){
    print "@row1\n";  # prints the current row
    @allrows = (@allrows,@row1);
    @IDnumber=@row1;
 }
  # allrows contains everything now
  # IDNumber contains the last row

@row1 in your code is only valid inside the loop-body, always use strict; and use warnings to fight scoping errors and "code better(tm)" ;-)
