这是2024年转载的最新SQL Server巡检脚本，SQL Server巡检脚本是一种用于定期检查SQL Server数据库健康状况的脚本。通常，巡检脚本包括检查数据库配置、性能指标和状态，以确保数据库的正常运行。例如，巡检脚本可以检查以下内容：
- 数据库备份状态
- 磁盘空间使用情况
- 数据库错误日志
- 数据库性能指标，如等待事件、锁定情况等
- 数据库安全性，如用户权限、审核日志等
执行巡检脚本可以及时发现数据库问题，从而避免严重的数据丢失或影响业务正常运行。
最新SQL Server巡检脚本
此脚本基于最新版本的sql server编写，SQL Server每个版本的函数基本都有变化，其他版本需要进行修改测试。大家可以根据官方的文章进行相应参数的修改。
官网地址：
https://learn.microsoft.com/zh-cn/previous-versions/sql/
二、脚本执行过程展示
1、新建查询
2、复制脚本
3、点击执行
4、查看结果
我们可以看到执行成功了，结果栏是执行sql结果的展示，消息栏是执行的结果打印，当然也可以将结果进行另存留档。
