MySql Menentukan Offset Baris Dari Hasil Query

Jadi dengan contoh tabel Anda:

username    ticket_number   queue_time
Doc             0               0                  The 1st 3 not in sorted result
Grumpy          0               0
Happy           0               0
Sleepy          1               111                The following are in sorted result
Bashful         2               222
Sneezy          0               333
SnowWhite       ???             444               This is the current user (assign ???=4)
Dopey           0               555
EvilQueen       0               666

cara menetapkan nilai 4 ke kolom ticket_number dari nama pengguna SnowWhite, 4 menjadi peringkat baris dalam pilihan yang diurutkan dari baris awal:

pertama dapatkan hasil yang diurutkan:

$result = mysql_query("SELECT * FROM table WHERE [here the condition for your sorted array]"); 
// don't forget to remove the []. they don't go there.
while ($row = mysql_fetch_assoc($result))
 {$array[] = $row;}

ini akan memberi Anda sesuatu seperti:

[0]   [username]        [Sleepy]
      [ticket_number]   [1]
      [queue_time]      [111]
[1]   [username]        [Bashful]
      [ticket_number]   [2]
      [queue_time]      [222]
[2]   [username]        [Sneezy]
      [ticket_number]   [0]
      [queue_time]      [333]
[3]   [username]        [SnowWhite]
      [ticket_number]   [NULL]
      [queue_time]      [444]

lalu foreach melalui array Anda

    foreach ($array as $number => $row)
     {if ($row[username] == $userinfo)
       {$result = mysql_query('UPDATE table SET ticket_numer=' . ($number+1) . ' WHERE username=' . $userinfo);}}

baris yang sesuai dengan nama pengguna SnowWhite akan mendapatkan ($number + 1) (3 + 1) sebagai ticket_number
