Tôi thích đề xuất của Martin về việc sử dụng thông báo sự kiện, vì vậy tôi đã theo liên kết ví dụ của anh ấy và kết hợp nó với máy chủ của chúng tôi. Bạn sẽ cần đặt địa chỉ email của mình trong cuộc gọi tới sp_send_dbmail hoặc sửa đổi quy trình đọc địa chỉ email từ một bảng cấu hình nào đó. Ngoài ra, điều chỉnh ngưỡng quá trình bị chặn theo ý thích của bạn. Kết quả là một thông báo báo cáo súc tích, với thông tin về các quy trình bị chặn và chặn.
Việc xử lý lỗi là thực sự cơ bản; nó chỉ kết thúc cuộc hội thoại nếu nhận được thông báo lỗi hoặc thông báo hộp thoại kết thúc.
Đảm bảo rằng Database Mail được cấu hình trên hệ thống của bạn để cho phép sử dụng sp_send_dbmail.
