我在perl中有这个脚本，这个程序解析一个日志文件并将结果发送到数据库中，我的问题是我的脚本只插入一个请求，我需要插入多个请求：

# Connect to the database.

my $dbh = DBI->connect("DBI:mysql:database=database;host=IP",
"hostname", 'password',
{'RaiseError' => 1});

while (my ($user, $ref) = each %counts) {
  while (my ($program, $count) = each %$ref) {
    #print "$count OSUSER with session $user and with program $program\n";
    print "time = $time, count = $count, user = $user, program = $program, last_line = $last_line\n";

    $request ="'$time', '$count', '$user', '$program', $last_line";

    my $sth = $dbh->prepare("REPLACE `test` (time, nb, os_name, program, last_line) VALUES($request);")
    or die "prepare statement failed: $dbh->errstr()";

    $sth->execute() or die "execution failed: $dbh->errstr()";
    print $sth->rows . " rows found.\n";
    $sth->finish;
  }
}

我的日志：

ID USER                    TERMINAL        SERVICE                    
---------- ------------------------- --------------- -------------------------

         2 toto                    titi     roro          
         4 gigi                    gege        fefe

我的数据库：

+----+---------------------+-----------+-------------+----------------+-----------+
| ID | time                | nb        | os_name     | program        | last_line |

我想要：

+----+---------------------+-----------+-------------+----------------+-----------+
| ID | time                | nb        | os_name     | program        | last_line |
