下面是一些你可以在夜间工作时使用的SQL编程。下面是如何操作：查看SQL数据库邮箱是否已经设置好。如何没有，系统会自动用一个通用的邮箱账号“SQL Database Mail”设置你的SQL数据库邮箱。然后它会发送邮件通知，当SQL数据库邮箱已经被设置好， 你就可以知道邮件都储存在哪。你只需要将你的服务器名称替换SMTP的服务器。然后检查有没有其他的数据库，需要从安全模式设置为FULL模式（ex.完整安全模式）。

Here’s some SQL Logic that you can throw into a nightly Job. Here’s what it does: Checks to see if SQL Database Mail has been configured. If not; it will automatically configure your SQL Database Mail using generic email profile called ‘SQL Database Mail’. Then it sends you an email notification when the SQL Database Mail has been configured using the name of the Database Server, and SQL Instance so you know where the email originated. All you need to do is replace the SMTP Server name with your server. Then it checks to see if you have any databases that have it’s safety mode set to FULL ( ex. SET SAFETY FULL )
