My SQL is a little rusty, but this query should be simple enough. I'm trying to get a list of all the emails in the all subscriber list that have a status of "unsubscribed" or "held" in the system. The following query errors on "_Subscribers is not a known data extension or system data view." I'm sure I don't have the table name correct, but I'm not sure what it is or how to find it.
SELECT EmailAddress, SubscriberKey, [Status] FROM _Subscribers WHERE [status] is ('unsubscribed','held')
