FAQ (Frequently Asked Questions)
What will happen if we perform update on after update trigger?
You can call this method in the trigger, but they will be executed after trigger ends, so no error will happen. For example, I used it to automatically fill some fields that require ID of record, that can’t be received in Before trigger.
What is difference between trigger new and trigger old?
The values in Trigger. old after the workflow update will NOT contain the “description” field that was updated in the workflow. The values in Trigger. new after the workflow update will contain any existing fields that were populated upon the object’s creation AND the “description” workflow updated field.
What is the difference between before trigger and after trigger?
Before triggers are used to update or validate record values before they’re saved to the database. After triggers are used to access field values that are set by the system (such as a record’s Id or LastModifiedDate field), and to effect changes in other records.
