Question 56/93

Which statement should be used to perform the DML necessary to insert new records and update existing records in a list of Order __c records using the external ID field?
Which statement should be used to perform the DML necessary to insert new records and update existing records in a list of Order __c records using the external ID field?
Correct Answer: D
Whyupsert?
Theupsertstatement inserts records that don't exist and updates existing records based on the external ID (Order Number__cin this case).
Salesforce automatically recognizes and uses the external ID field for matching.
Why Not Other Options?
A and B:mergeis for merging records, not for upserting.
C: Adding the field name afterupsertis unnecessary, as Salesforce detects the external ID automatically.
