我想查找特定数据，例如国家名称“西班牙”或任何人名，例如“约翰”

那么有没有办法找到哪个表的列包含数据Spain或John在 SQL Server 数据库中（记住这些不是列名，这些是存储在列中的值）

试试下面的存储过程，我在这里找到了。

创建此存储过程并传递您要查找的数据

只要我可以使用市场上已经存在的一些免费工具，我就不会为任何复杂的存储过程而烦恼。只需安装其中任何一个，您就可以更快地完成工作。

SSMS 工具包——仅搜索数据。除 2012 之外的所有版本均免费

ApexSQL 搜索 – 搜索对象和数据

还有来自 Red Gate 的 SQL Search，但我自己从未使用过。
