FAQ (Frequently Asked Questions)

What is before insert trigger in Salesforce?

Before insert: When using this event, the code block is executed before a new record is inserted. Before update: When you use this event, the code gets executed before a new record is updated in the object.

What is an apex trigger?

Apex triggers enable you to perform custom actions before or after events to records in Salesforce, such as insertions, updates, or deletions. Triggers can be defined for top-level standard objects, such as Account or Contact, custom objects, and some standard child objects. Triggers are active by default when created.

What are the two options for when Apex triggers can run?

Apex Triggers can either run before a record has been saved of after. A before operation is usually used to verify information that is going to be inserted, and after trigger is used to access data that has previously been entered by a user or system.
