Mate, Anda membiarkan email caroline****@****.com pada contoh kode Anda di atas.

Versi SQL yang lebih baru mendukung daftar proses di information_schema:

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST

Anda dapat memesan dengan cara apa pun yang Anda suka.

Tabel INFORMATION_SCHEMA.PROCESSLIST telah ditambahkan di MySQL 5.1.7. Anda dapat mengetahui versi mana yang Anda gunakan:

SELECT VERSION()

Ini sangat bagus, tetapi sama dengan show full processlist, katakanlah, INFObagian ini selesai, apakah ada versi pendek? Atau mungkin saya perlu menggunakan substr
omg
@Shore: kamu ingin melakukan substr?

Perintah 

show full processlist

dapat diganti dengan:

SELECT * FROM information_schema.processlist

tetapi jika Anda menggunakan versi yang terakhir Anda dapat menambahkan WHEREklausa untuk itu:

SELECT * FROM information_schema.processlist WHERE `INFO` LIKE 'SELECT %';

Alat lain yang berguna untuk ini dari antarmuka baris perintah, adalah perintah pager.

misalnya

pager grep -v Sleep | more; show full processlist;

Kemudian Anda bisa melihat-lihat hasilnya.

Anda juga dapat mencari pengguna, IP, atau kueri tertentu dengan grep atau sed dengan cara ini.

Perintah pager persisten per sesi.

Anda bisa menangkap output dan meneruskannya melalui filter, seperti:

mysql show processlist
    | grep -v '^\+\-\-'
    | grep -v '^| Id'
    | sort -n -k12

Dua greps menghapus baris header dan trailer (yang lain mungkin diperlukan jika ada baris lain yang tidak mengandung informasi yang berguna) dan pengurutan dilakukan berdasarkan angka bidang angka 12 (saya pikir itu benar).

Yang ini berfungsi untuk hasil langsung Anda:

mysql show processlist
    | grep -v '^\+\-\-'
    | grep -v '^| Id'
    | grep -v  '^[0-9][0-9]* rows in set '
    | grep -v '^ '
    | sort -n -k12

Anda tidak perlu menelepon grepempat kali berturut-turut; gunakan saja sedseperti sed '/^\+\-\-/d; /^| Id/d; /^[0-9][0-9]* rows in set '/d; /^ /d;ini : Ini membuat satu panggilan ke satu program (bukan empat), dan lebih cepat, lebih bersih, lebih sederhana, dan itu berjalan lebih cepat juga.

Anda tidak perlu, tidak, tetapi Anda bisa. Jika itu jenis hal yang ingin Anda lakukan berkali-kali per detik, ya, khawatir tentang kinerja. Kalau tidak, itu bukan masalah, terutama mengingat ukuran set data.

... Kami belum memiliki versi MySQL yang lebih baru, jadi saya dapat melakukan ini (hanya berfungsi pada UNIX):

 host=maindb

 echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Locked

Di atas akan meminta semua sesi yang terkunci, dan mengembalikan informasi dan SQL yang terlibat.

... Jadi- dengan asumsi Anda ingin meminta sesi yang sedang tidur:

  host=maindb

  echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Sleep

Atau, anggap Anda perlu memberikan parameter koneksi tambahan untuk MySQL:

  host=maindb

  user=me

  password=mycoolpassword 

  echo "show full processlist\G" | mysql -h$host -u$user -p$password | grep -B 6 -A 1 Locked

Dengan beberapa tweak, saya yakin skrip shell dapat dengan mudah dibuat untuk meminta daftar proses seperti yang Anda inginkan.
