I want to be able to use two fields in combination to uniquely identify a record. For example, I want to have an Item Number and a Production Line in combination (i.e. Item Number "4060" and Production Line "Line 1" is a record; and Item Number "4060" and Production Line "Line 2" is a record. Is this possible?
Reply from Richard Rost:
Yep. That's what composite keys are for. More importantly, composite keys ensure that that COMBINATION of data is unique.
