您可能需要为数据库构建一个倒立索引。它肯定是相当快的。

如果你安装了phpMyAdmin，使用它的搜索功能。

选择您的数据库。

请确保您选择的是DataBase，而不是表，否则您将得到一个完全不同的搜索对话框。

单击“搜索”页签 列表项选择所需的搜索词 选择要搜索的表

您可能需要为数据库构建一个倒立索引。它肯定是相当快的。

如果您只需要运行一次这样的搜索，那么您可能可以使用其他答案中已经显示的任何脚本。但除此之外，我建议使用ApexSQL搜索。这是一个免费的SSMS插件，它真的为我节省了很多时间。

在运行任何脚本之前，您都应该根据要搜索的数据类型自定义脚本。如果你知道你正在搜索datetime列，那么就没有必要通过nvarchar列进行搜索。这将加快上面所有查询的速度。

我优化了Allain Lalonde的答案(https://stackoverflow.com/a/436676/412368)。 仍然支持数值。应该大约快4-5倍(1:03 vs 4:30)，在带有7GB数据库的桌面上测试。http://developer.azurewebsites.net/2015/01/mssql-searchalltables/
