What part of a database trigger determines the number of times the trigger body executes?

  1. Trigger type

  2. Trigger body

  3. Trigger event

  4. Trigger timing


Correct Option: A

AI Explanation

To answer this question, you need to understand the different components of a database trigger.

A database trigger is a stored program that automatically executes in response to an event, such as a data modification operation (insert, update, delete) performed on a specified table. The trigger consists of three main parts: the trigger event, the trigger timing, and the trigger body.

The trigger event (option C) determines when the trigger should execute, such as before or after an insert, update, or delete operation on a table.

The trigger timing (option D) determines whether the trigger executes before or after the triggering event occurs.

The trigger body (option B) contains the code or instructions that are executed when the trigger is fired.

The part of a database trigger that determines the number of times the trigger body executes is the trigger type (option A). The trigger type specifies whether the trigger is a row-level trigger or a statement-level trigger.

  • A row-level trigger executes once for each row affected by the triggering event.
  • A statement-level trigger executes once for each triggering event, regardless of the number of rows affected.

Therefore, the correct answer is option A) Trigger type. This option is correct because the trigger type determines the number of times the trigger body executes.
