Orphan record example?

Computers and Technology
1 answer:
Goryan [66]3 years ago
4 0

Answer:

If we delete record number 15 in a primary table, but there's still a related table with the value of 15, we end up with an orphaned record. Here, the related table contains a foreign key value that doesn't exist in the primary key field of the primary table. This has resulted in an “orphaned record”.
