我不在乎它是否快速，它只需要工作。

This might help you。 - 来自Narayana Vyas。它搜索给定数据库中所有表的所有列。我之前使用过它并且有效。
这是上面链接中的存储过程 - 我做的唯一更改是将临时表替换为表变量，因此您不必每次都记得丢弃它。

如果您只需要运行一次此类搜索，那么您可以使用其他答案中已显示的任何脚本。但除此之外，我建议使用ApexSQL Search。这是一个免费的SSMS插件，它确实为我节省了很多时间。
在运行任何脚本之前，您应该根据要搜索的数据类型对其进行自定义。如果您知道正在搜索datetime列，则无需搜索nvarchar列。这将加快上述所有查询。
答案 2 :(得分：67)
根据bnkdev的回答，我修改了Narayana's Code来搜索所有列，甚至是数字列。
它会运行得更慢，但这个版本实际上找到的所有匹配项不仅仅是在文本列中找到的匹配项。
我不能完全感谢这个家伙。救了我几天手工搜索！
