问题描述
我正在使用Ruby，并且尝试将'字符转义为\'，以便可以在SQL中使用它们.我正在尝试使用gsub，但是它似乎没有用.
I'm working in Ruby and I'm trying to escape ' characters to \' so that I can use them in SQL. I'm trying to use gsub, but it doesn't seem to be working.
"this doesn't work".gsub /'/, '\\'' #=> "this doesnt workt work"
"this doesn't work".gsub /'/, '\\\'' #=> "this doesnt workt work"
"this doesn't work".gsub /'/, '\\\\'' #=> "this doesn\\'t work"
"this doesn't work".gsub /'/, '\\\\\'' #=> "this doesn\\'t work"
我不知道gsub是否是正确的使用方法，所以我愿意尝试几乎所有能够获得所需结果的方法.
I don't know if gsub is even the right method to be using, so I'm willing to try almost anything that gets the results I'm looking for.
推荐答案

这行吗?
