Hinweise
DDL triggers run a Transact-SQL or user-defined function in response to certain DDL events.
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 DatabaseDdlTrigger object properties, users can be a member of the public fixed server role.
To set DatabaseDdlTrigger object properties, users must have ALTER ANY DATABASE DDL TRIGGER permission on the database.
To create a DDL trigger, users must have ALTER ANY DATABASE DDL TRIGGER permission on the database.
To drop a DDL trigger, users must have ALTER ANY DATABASE DDL TRIGGER permission on the database.
To enable or disable the DDL trigger, users must have ALTER ANY DATABASE DDL TRIGGER permission on the database.
