Sql server 如何在数据库中搜索文本字符串？

有没有办法在整个SQL Server数据库中搜索文本字符串

---

“整个数据库”指的是表、视图、存储过程等。

如果“数据库”指的是包括过程源代码在内的所有内容，那么最简单的方法可能是生成数据库转储并在结果文件中搜索字符串。这比在信息模式上运行各种查询都要简单。

以下是搜索存储过程中某些文本的代码

SELECT Distinct SO.Name
FROM sysobjects SO (NOLOCK)
INNER JOIN syscomments SC (NOLOCK) on SO.Id = SC.ID
AND SO.Type = 'P'
AND SC.Text LIKE '%test%'
ORDER BY SO.Name

下面是搜索存储过程中某些文本的代码

SELECT Distinct SO.Name
FROM sysobjects SO (NOLOCK)
INNER JOIN syscomments SC (NOLOCK) on SO.Id = SC.ID
AND SO.Type = 'P'
AND SC.Text LIKE '%test%'
ORDER BY SO.Name

我得到了使用存储过程显示/搜索所有表、列和SP的解决方案：

在数据或定义方面，还是两者兼而有之？它关系到数据或定义，还是两者都重要？这对你的暗示很重要。我试试这个。谢谢你的提示。我会试试这个。谢谢你的提示。由于我有时会搜索多个主题/库，因此如果是要运行的存储过程或要显示的视图，那么获得一个“一目了然”的概述将很有帮助。由于我有时会搜索多个主题/库，因此如果是要运行的存储过程或要显示的视图，那么获得一个“一目了然”的概述将非常有帮助。
