有没有一种方法可以在一个 MS SQL Server 数据库内的任何表的任何列中搜索一个值（在我的情况下，它是 char(64) 类型的 UID）？
我坐在一个巨大的数据库前，不知道如何将这些表链接在一起。要找出这一点，我想列出所有表以及任何行中包含特定值的列。这可能吗？
一种方法可能是将整个数据库转储到一个文本文件中，然后使用任何文本编辑器搜索该值 - 但如果数据库太大，这将是纯粹的痛苦。

下面提到的所有第三方工具都是 100% 免费的。
我使用ApexSQL Search 在表格中搜索对象和数据时取得了很好的成功。它还具有其他几个功能，例如关系图等……
我在大型（40GB TFS 数据库）数据库上有点慢……
除此之外，还有SSMS Tools pack 提供了许多非常有用的其他功能，即使这些功能与搜索文本没有直接关系。

我扩展了代码，因为它没有告诉我'record number'，我必须重新找到它。

我有一个不久前的解决方案，我一直在改进。如果被告知，还会在 XML 列中搜索，或者如果提供仅整数字符串，则搜索整数值。

我在 https://gallery.technet.microsoft.com/scriptcenter/c0c57332-8624-48c0-b4c3-5b31fe641c58 找到了一个相当强大的解决方案，我认为值得指出。它搜索以下类型的列：varchar、char、nvarchar、nchar、text。它工作得很好，并且支持特定的表格搜索以及多个搜索词。
【讨论】：
有一个不错的脚本可用 http://www.reddyss.com/SQLDownloads.aspx
为了能够在任何数据库上使用它，您可以像这样创建它： http://nickstips.wordpress.com/2010/10/18/sql-making-a-stored-procedure-available-to-all-databases/
不知道有没有其他办法。
要使用它，请使用以下内容：
use name_of_database
EXEC spUtil_SearchText 'value_searched', 0, 0
【讨论】：
在尝试@regeter's solution 并在我搜索外键/主键以查看它存在的所有表/列时看到它并没有解决我的问题后，它不起作用。在阅读了另一个尝试使用唯一标识符的人如何失败后，我进行了修改，这是更新后的结果：（适用于 int 和 guid...您将看到如何轻松扩展）
