推荐答案

我不会通过您的可怕的正则表达式并修复所有问题，但是如果您确实希望将其插入数据库中，则：

I'm not going to through that hideous regexp of yours and fix it all, but if you do want to insert it into your database, then:

• 使用单引号（'）包围整个正则表达式字符串。目前，您正在使用双引号（ ）。



• 在字符串中使用两个单引号表示一个单引号字符串中的-quote字符。例如

• Use single quotes (') to surround the entire regexp string. At the moment you are using double quotes (").

• Use two single quotes inside a string to represent a single-quote character within the string. For example

 SELECT 'Don't do this' FROM some_table

会因错误而失败，但是

 SELECT 'It''s better to do this' FROM some_table

将选择字符串最好这样做。
