I want to make this display only the rows of data that do not have a value in the total_time (data type INTEGER) field. Along with the oid of each row displayed. 
#!/usr/bin/perl

use CGI qw/:standard/;
require "common.sub";

print header;

&Create_DB_Connection;
&get_info;
&print_results;

# Disconnect from the database
$dbh->disconnect;


################ BEGIN GET INFO SUBROUTINE
sub get_info{
  $SQL="SELECT oid,* FROM timeclock WHERE total_time = 0 ORDER BY l_na
+me";
  #my $sth = &Do_SQL;
  &Do_SQL;
}
################ END GET INFO SUBROUTINE
