Membuat TRIGGER pada database MySQL

Trigger?????? pasti pada lari kalo dengar triger,,, nech dah terbukti pada saat praktikum kemarin….mendengar namatriger seperti melihat hantu ternyata.. :).. ne sekilas tentang triger…

Trigger adalah suatu prosedur yang otomatis akan dijalankan apabila “pemicu” dari trigger itu dipanggil.

sebagai contoh: penghapusan satu tabel akan memicu suatu trigger untuk menghapus pada tabel yang lain yang telahditunjuk terlebih dahulu. dibawah ini saya berikan satu contoh penggunaan trigger pada database MySQL.

Sebagai contoh kita siapkan terlebih dahulu sebuah database dan tabel yang akan diuji coba seperti dibawah ini:

Kemudian buatlah sebuah trigger dengan kode seperti dibawah ini:

pada trigger di atas setiap kali perubahan dilakukan terhadap tabel COBA maka secara otomatis
tabel COBA2 akan dipengaruhi / terpengaruh.
Pembuatan trigger ini dapat digunakan untuk berbagai keperluan, selamat mencoba…..!

  1. Pasang plugin untuk penulisan kode sumber, supaya ga harus pasang gambar kekecila seperti itu. Lagian ngapain juga harus lari karna trigger, emangnya mukanya mirip pocong apa?

  6. With almost everything which seems to be building throughout this particular subject matter, many of your viewpoints are quite stimulating. Even so, I am sorry, because I can not subscribe to your whole suggestion, all be it stimulating none the less. It looks to everybody that your opinions are actually not entirely validated and in simple fact you are generally your self not even thoroughly certain of your assertion. In any case I did enjoy examining it.
