One of my favorite web services, YQL is now even easier to use. They’ve recently added a Query Builder to the YQL console, so now it’s so much easier to figure out which keys are available in tables.
Previously I found I had to dig deep into an XML file, and use a lot of trial and error to figure out what keys were available, but he Query Builder now handles the majority of that for me. It also exposes the metadata in a friendly visual format, which is another great thing too.
Sub-queries aren’t supported yet, but hopefully that’s something that they might be able to add in the not too distant future.
All the details are mentioned on their blog with a nice screencast going over how to use it.
All in all a very impressive improvement to an already great service.
