FAQ (Frequently Asked Questions)

How would you write a trigger to count the number of tasks associated with an account?

You can write an 'after insert', 'after update', and 'after delete' Trigger on the Task object. Within this Trigger, count the number of Tasks related to each Account.

What is the difference between before and after trigger in Salesforce?

Before Triggers are ideal for making changes to the triggering record, while After Triggers are suitable for working with related records and system-generated field values. Understanding this distinction is key to designing effective and efficient trigger logic in Salesforce.

How many triggers we can write on the same object with same trigger event?

Use only one trigger per object principle. Minimize the use of SOQL query and DML operations. Avoid trigger recursion via a static variable when performing an update on the same object from the trigger.
