Trigger.new in Salesforce returns a list of the new version of sObject records, and is available in insert, update, and undelete triggers.
Trigger.new in Salesforce Example:
| trigger AccountTrigger on Account (before insert) { for (Account acc: Trigger.new) { acc.NumberOfEmployees = 100; } } |
In this example, Trigger.new allows us to modify the NumberOfEmployees field before the record is inserted into the database.
trigger ApexTrigger on Account(before insert) {
for (Account acc: Trigger.new) {
acc.NumberOfEmployees = 100;
}
}
