Hi I got assignment due, I've doe everything but I cant see to do this:
1. Alter the database so that the serial number can be recorded at the time of sale.
.
2. In order to improve the integrity of the data as it enters the database, you should implement the following business rule:
When a serial number is recorded in a sale, the quantity purchased must be one. In other words — the serial number must be blank or the quantity must be 1
This might seem easy but Im so stuck, been stuck for 2 hours already . The Data type of SerialNoRequired is Yes/No which cannot be changed in the assignment. Here is the ERD for this assignment:
