This ensures data integrity and enables efficient data retrieval and manipulation. How To Create Primary and Reference Key In SQL Server To create primary and foreign keys in SQL Server, use the "PRIMARY KEY" constraint to uniquely identify records in a table and the "FOREIGN KEY" constraint to establish a link between tables based on a common key.
