sys.dm_xe_database_session_events (Azure SQL Database and Azure SQL Managed Instance)

  • Άρθρο

Applies to: Azure SQL Database Azure SQL Managed Instance

Returns information about session events for active database-scoped sessions. Events are discrete execution points. Predicates can be applied to events to stop them from firing if the event does not contain the required information. For information on events in all database-scoped sessions, see sys.database_event_session_events.

Azure SQL Database supports only database-scoped sessions. Azure SQL Managed Instance supports both database-scoped sessions and server-scoped sessions. Server-scoped sessions are recommended for managed instances: learn more in CREATE EVENT SESSION.
