sql server数据库中，每天都要执行一小段代码，比如会员卡过了有效期以后就要将卡状态改为“失效”。现在是在企业管理器中手工新建一个作业，但是如果发布程序以后，就不应该还用人工方式来新建作业，应该有程序自动来添加作业。但是怎么用代码生成一个作业呢？
------解决方案--------------------
先手工创建Job，然后右键生成脚本即可。

给你一个例子

-- Server: (LOCAL)
BEGIN TRANSACTION

-- Delete the job with the same name (if it exists)
SELECT @JobID = job_id
