Answer Posted / Ankush Soni
A Referential Join is a type of database join used to relate two tables by using foreign keys and primary keys. In SAP HANA, this helps in maintaining Referential Integrity, which ensures that relationships between tables are kept consistent. If a parent table's primary key value is deleted or updated, the corresponding changes will be reflected in the child table.
