Quotes inside a string

[meijin]

Hi,

I need to create a string that has quotes inside it. I would think this would be trivial, but I haven't been able to do it nor have I found any documentation on the topic. I basically need something like this:

"Alfa "alfa" beta"

where all of it is a string. I am trying to pass the whole string to a query.

Escape the double-quote character with a backslash. Good luck.

"Alfa "alfa" beta"

Code: Select all

"Alfa \"alfa\" beta"

There are actually some pretty clever tools out there that will help you with this as well. You could take a look at CL-INTERPOL (http://weitz.de/cl-interpol/) which, among other things, allows you to avoid having to escape quotes. It defines a reader syntax where you can use balanced delimiters like { and } to designate open and close of strings which fixes the entire issue of having to escape quotes (as long as the delimiters are balanced in the string). i.e.

Code: Select all
