Hinweise

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.
