How automatically add 1 year date to an existing date in SQL Server

Question

I have a task to automatically bill all registered patients in PatientsInfo table an Annual Bill of N2,500 base on the DateCreated column.

Answer 1

Assuming the columns of the 2 tables are the same:

INSERT INTO PatientDebit
SELECT * from PatientsInfo WHERE DateCreated

Make sure you have an index on DateCreated if PatientsInfo has a lot of records as it could potentially be slow otherwise
