Instead of inserting values into every column, SQL allows you to specify only the required columns. Remaining columns receive their default values or NULL if permitted.
Business applications often collect only partial information during the first stage of data entry.
During employee registration, HR records only EmployeeID and EmployeeName. Department and Salary are updated later.
INSERT INTO Employees
(
EmployeeID,
EmployeeName
)
VALUES
(

'Karan Singh'
);Registration forms, customer onboarding systems, online applications, and CRM software frequently insert partial records.
