The sys.database_event_session_events dynamic management view (DMV) returns a row for each event in a database-scoped event session. For information on events in active database-scoped sessions, see sys.dm_xe_database_session_events.
- Azure SQL Database and SQL database in Fabric support only database-scoped sessions.
- Azure SQL Managed Instance supports both database-scoped sessions and server-scoped sessions. Server-scoped sessions are recommended for SQL managed instances. For more information, see CREATE EVENT SESSION code examples.
