What is a foreign key in SQL Server? A foreign key is a way to enforce referential integrity within your SQL Server database. A foreign key means that values in one table must also appear in another table. The referenced table is called the parent table while the table with the foreign key is called the child table.
Hi srikar, A foreign key is the field (or fields) that points to the primary key of another table. The purpose of the foreign key is to ensure referential integrity of the data.
