sp_msforeachdb的替代方法

时间：2019-03-11 16:27:27

标签： sql-server

我继承了下面的脚本，并努力在不同实例的所有数据库上运行该脚本。当我使用sp_msforeachdb时它可以工作，但它不会以我想要的方式输出，它还为没有数据的数据库提供了空白结果集，这是使用sp_msforeachdb问题的一部分...我觉得这是我尝试过的联接不同的形式，但仍然没有输出我想要的方式。请查看并提供反馈。

删除USE ?;之后的分号，这就是为什么总是从同一数据库获取结果的原因。

要排除系统表，sp_foreachdb已经有一个名为@user_only的参数，您不需要在末尾添加

此外，您的查询大于2000个字符
