Bây giờ tạo một công việc SQL Agent. Hãy chắc chắn rằng bạn thay đổi set @threshold = 20 --->>>>>>>>>>>>>>>>> CHANGE HERE <<<<<<<<<<<<<<<<<<<<<---trong kịch bản dưới đây. Tôi đã đặt anh ta như một ngưỡng rất thấp, chỉ để mô phỏng cảnh báo. Lịch trình công việc để chạy cứ sau 30 phút (thay đổi điều này theo nhu cầu của bạn).
