问题描述
所以我找到了一种在SQL92兼容的RDBMS中进行简单正则表达式和LL（1）解析的方法，使用存储过程和一些表进行解析和扫描。
这样做的结果是，如果你传递复杂的结构化文本数据 - 从URL到电子邮件的任何东西，比如JSON，你可以得到验证的东西，甚至可以为你规范化数据。
我不想把精力花在任何人不在乎的事情上，而且我多年来一直没有做生意。
这样的东西还有用吗？
我尝试了什么：
我还没有尝试过任何东西。这不是真正的那种问题
So I figured out a way to do simple regex and LL(1) parsing inside a SQL92 compliant RDBMS, using stored procs and a few tables for parsing and scanning.
The upshot of this is if you pass complicated structured textual data - anything from an URL to an email addy, to say, JSON, you can get the thing to validate and perhaps even normalize the data for you.
I don't want to expend the effort on something nobody cares about anymore though, and I've been out of business dev for years.
So is something like that useful still?
What I have tried:
I haven't tried anything yet. This isn't really that kind of question
