Notes
DDL triggers run a Transact-SQL or user-defined function in response to certain DDL events.
SQL Server Management Objects (SMO) provides programmatic access to allow management of all DDL trigger functionality with the DatabaseDdlTrigger object and the ServerDdlTrigger object.
Database DDL triggers respond to events within the scope of the database and server DDL triggers respond to events within the scope of the SQL Server instance.
To get ServerDdlTrigger object properties, users can be a member of the public fixed server role.
To set ServerDdlTrigger object properties, users must have CONTROL SERVER permission on the server or be a member of the sysadmin fixed server role.
To create or drop a server-level DDL trigger, users must have CONTROL SERVER permission on the server or be a member of the sysadmin fixed server role.
Thread Safety
Tout membre statique public (Partagé dans Microsoft Visual Basic) de ce type est sûr dans le cadre des opérations à plusieurs threads. Tous les membres de l'instance ne sont pas garantis comme étant thread-safe.
Exemples
Création, modification et suppression de déclencheurs
Sécurité des threads
Tous les membres publics static (Shared dans Visual Basic) de ce type sont thread-safe. Tous les membres de l'instance ne sont pas garantis comme étant thread-safe.
