Enables or disables a trigger or changes its creation timestamp.

Some utilities, such as FastLoad and MultiLoad, cannot operate on tables with enabled triggers. Disabling the triggers enables bulk loading of data into the tables. Although the Teradata Parallel Data Pump utility operates on tables with enabled triggers, performance issues can occur.

Some triggers coordinate actions on a set of tables. If these triggers are disabled for some period of time, the application must ensure that the relationship among the set of tables and the trigger is not lost.

Privileges

To execute ALTER TRIGGER, you must have the DROP TRIGGER privilege on the table on which the trigger is defined, or on the database containing it.

There are no privileges granted automatically.
