Hi Jiashri,
  • For this, you can reference the Trigger.oldMap and Trigger.newMap map collections. So, you can compare old values with new values.
  • So, the Trigger will always 'fire' but you will only act upon it if the new and old values are different
Check the reference below from Stack Exchange.

Important Update - what you need to do
User-added image
As a reminder, on December 4, 2023 the Salesforce Discussion Forums will be removed from the Salesforce Developers website. These forums will shut down and all relevant discussions will migrate to the Trailblazer Community digital platform.

During the week starting November 20, you can view discussions, but not post new questions or responses. On December 4, you will no longer be able to access the discussion forums from the Salesforce Developers website.

Please take these steps before November 30, 2023, 11:59 p.m. PT to ensure your contributions follow you to the Trailblazer Community:
  1. If you’re not already a member of the Trailblazer Communitysign up for a Trailblazer account using the same login email address associated with your Developer Discussion Forums account. This is crucial.
  2. If you already have a Trailblazer account, and it’s using a different email address from your Developer Discussion Forums account, we recommend that you log in to the Trailblazer Community and connect your forums email address to your Trailblazer account.

We know that moving platforms can be a hassle, so we created a special forums users group, the Migration Support Hub, in the Trailblazer Community where you can get training videos, information, and assistance.

We are here to help you through this transition!
