The SQL statement in question does not return any records because it is joining on the EmailAddress field, which is not present in the _Bounce Data View. The correct approach is to join using the SubscriberKey (or SubscriberID). Here is the corrected SQL statement:

SELECT s.EmailAddress, s.SubscriberKey, b.JobID, b.EventDate, b.SMTPBounceReason FROM _Subscribers s JOIN _Bounce b ON s.SubscriberKey = b.SubscriberKey WHERE b.EventDate > DateAdd(DAY, -30, GETDATE())

This ensures that the join is based on the SubscriberKey, which is a common field in both data views.
