Question

What are the three ways that anonymous blocks can be executed?

Answer 1

Anonymous blocks in computer programming can be executed through direct execution, trigger execution, and scheduled execution.

Step-by-step explanation:

Anonymous blocks in computer programming languages can be executed in three ways:

1. Direct Execution: This involves running the code within the anonymous block directly, either by clicking a button or executing it manually.
2. Trigger Execution: Anonymous blocks can be executed as a response to certain triggers, such as a specific event happening in a program or system.
3. Scheduled Execution: An anonymous block can be scheduled to run at a specific time or on a predefined schedule, using tools like cron jobs or Windows Task Scheduler.

For example, in a programming language like JavaScript, you can execute an anonymous block of code directly by enclosing it within {} brackets and running it. Similarly, in Oracle PL/SQL, you can define a trigger that executes an anonymous block when a specific event occurs.
