Which of the following is true concerning triggers?

  • A.You do not create them with SQL.
  • B.They execute against only some applications that access a database.
  • C.They have an event, condition, and action.
  • D.They cannot cascade (cause another trigger to fire).

Answer: C

Correct answer: They have an event, condition, and action.

The three parts define a trigger: the event that fires it, an optional condition restricting when it acts, and the action it performs. It is created with SQL, applies to every route into the database rather than to particular applications, and can perfectly well cause another trigger to fire.
