Can I confirm that the node_id is the number after the period at the end of the url of the node?
The node I'm trying to use this for has a node ID 92, I've tried adding 92 and "92" as a replacement for node_id, both cases I get:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"92", user_id, notify_on, send_alert, send_email)
select 1, user_id, 'thread', 1' at line 1
