Can anyone tell me why this works:
https://graph.facebook.com/fql
?q=SELECT display_name FROM application WHERE app_id=0&access_token=...
(and returns 0 results, obviously)
but this doesn’t:
https://graph.facebook.com/fql
?q=SELECT display_name FROM application WHERE app_id>=0&access_token=...
(HTTP 500)
The FQL pages on Facebook itself only ever give the simplest of queries – they never give samples of more complex queries involving strpos() and anything other than =.
I am aware of the need to work on an indexed column, but app_id is definitely one of those 🙂
If the column is indexable you still need to provide specific values for it.
If you could provide vague ranges (e.g. ‘>0’) it would defeat the restriction of requiring you to specify the target objects first, and filter later
