Bulk Apex Triggers

Concepts

Triggers fire on up to 200 records at a time. Bulk triggers loop over Trigger.new, query once outside the loop, and run DML once on a list.

Hands-On Challenge

1. Create a trigger ClosedOpportunityTrigger on Opportunity, after insert and after update.
2. For each opportunity with stage Closed Won, create a task with subject Follow Up Test Task.
3. Insert all tasks with one DML statement.
