What are triggers in Apex?
Apex triggers enable you to perform custom actions before or after changes to Salesforce records, such as insertions, updates, or deletions. A trigger is Apex code that executes before or after the following types of operations: insert. update. delete.
Can we use trigger new in before insert?
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. Before delete: When you're using this event, the record gets deleted before the execution of the code block.
What are bulk triggers?
All triggers are bulk triggers by default, and can process multiple records at a time. You should always plan on processing more than one record at a time. An Event object that is defined as recurring is not processed in bulk for insert , delete , or update triggers.
