这可能对你有帮助. - 来自Narayana Vyas.它搜索给定数据库中所有表的所有列.我之前使用它并且它有效.
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.

基于bnkdev的回答,我修改了Narayana的代码来搜索所有列甚至数字列.
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!

这是我对这个问题的独立看法,我将其用于自己的工作.它适用于SQL2000及更高版本,允许使用通配符,列过滤,并将搜索大多数普通数据类型.

我前一段时间有一个解决方案，我一直在改进。如果被告知这样做，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。
