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.
What is the purpose of a primary key in a database? The primary key is the field-or combination of fields-that uniquely identify each record in a table. It is usually the primary key that is stored in other tables (in which â¦ case it is called a foreign key), to find the record in the specified table. For example, a client might be identified by a field ClientId, which uniquely identifies each client. In the client table, this field would be called the primary key; if used in other tables to refer to a client, it is called a foreign key. 40 people found this useful.
