If you attempt the deletion via the execution of the Salesforce API and the database returns an error due to a restriction, your can catch this exception and customize the message before displaying it to the user, or for recurring issues, consider adding a notification or suggestion within the application that advises users of the restriction on accounts with closed-won opportunities.

Thank @ Amit , Excellent work once again !!!! I request you to please make some more use case videos on the trigger, trigger handler, and helper class, and test class for the same example.

[@mrinalkishore4424]

Your videos are good and very helpful. Im surprised they have so less views

[@JaimeBIDtravel]

Very clear explanation. What about if logic is a bit more complex and many steps are needed. Would that mean many methods within the same class? How to concatenate them?

[@sfdcpanther]

If it's a bit complex then there might be many methods based on the requirement.

[@SarGuP]

Can we use oldmap in the first for loop to throw the error so we don't need second trigger

what if I do like this ? If(Trigger.isBefore && Trigger.isDelete) { List acclist=New List(); List accountwithopp=[Select Id,Name, (Select Id,Name,StageName from Opportunities where stageName='Closed Won') from Account]; for(Account acc:trigger.old) { for(Account acc1:accountwithopp){ if(acc.id==acc1.id) { acc.addError('You can not delete closed won opportunity'); } } } }

[@sfdcpanther]

That's your choice. No one is stopping you. The purpose is to use Helper & handler classes because that is the best practice and easy to maintain and understand when you leave the company. Also, If you have bulk data your code will break for querying more than 50K rows.
