database pemulihan smo

Saya berhasil menggunakan SMO untuk memulihkan basis data. Saya akan membagikan kode saya. Semoga membantu. Solusi ini memiliki satu peringatan, ini menganggap Anda hanya memiliki satu file data primer. Mendapatkan untuk mencocokkan log dan file data benar-benar rumit dan sesuatu bisa salah dalam banyak hal. Pokoknya coba dan beri tahu saya bahwa ini membantu.
