I'm trying to figure out how to escape a single quote for a query of a Usergrid collection. I can't find anything about it in the documentation or online. For example I have a Book collection and I want to select those with the title "Charolette's Web"
/books/?ql=select*where title = 'Charlotte\'s Web'
This query does not give back any results from the database query. I also tried '' as the escape character (like sql) but that didn't work either.
As far as I know, there's no way to escape quotes in a ql request at the current time.
You could work around this by using a contains clause:
?ql=select * where title contains 'Charlotte'
I've opened an issue for it to be looked at here.
