不区分大小写的RegEx模式

Question

I want to search for strings that have: Code[spaces]VARCHAR

Currently I'm using: \\bCode\\s+VARCHAR\\b

How would I make this case insensitive?

Answer 1

Reference

Try this

/\bCode\s+VARCHAR\b/i

Or

(?i)\bCode\s+VARCHAR\b

Explained here

Answer 2

Which Regex engine do you use ? For most of them you can give a 'i' flag (insensitive) at the end of your regex

Like that :

/\bCode\s+VARCHAR\b/i

or sometimes as a function parameter :

string.match("\bCode\s+VARCHAR\b", "i")

Answer 3

在java（以及其他语言）中，您可以在正则表达式中添加不区分大小写的标志(?i) ：

(?i)\bCode\s+VARCHAR\b
