What is a natural primary key?..

Answer / Nirbhay Raj Singh

A natural primary key in SQL Server is a column or combination of columns that already contains unique values and are used as the primary key, without adding any explicit constraint. For example: CREATE TABLE Customers ( CustomerID INT PRIMARY KEY,n CustomerName NVARCHAR(50),n ... ) In this case, 'CustomerID' is a natural primary key.
