About this document

Understanding Foreign Keys in Oracle by Raja Shekarr is a document available to read on EtoBox.

A foreign key in Oracle enforces referential integrity by ensuring that values in one table (child table) must appear in another table (parent table). It can be defined during table creation or modified later using an ALTER TABLE statement, with options for actions on delete or update such as ON DELETE CASCADE. Examples are provided for creating foreign keys both during table creation and via ALTER TABLE, including support for multiple fields.
