A developer wants to expand their knowledge of Query Activities.

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.
