Hey guys,

I'm currently in the design stage of a database, and have a question of how the keys should be set up in two of my tables.

I have an Orders table, which is related to a Customers table, and also to an Images table.
The orders table has OrderID (PK), CustID (FK), and ImageSetID (PK)

The ImageSetID field joins to the Images table which contains ImageSetID (FK), ImageID (PK), and ImagePath

Now, I plan to have multiple images for each order, which all will have a common ImageSetID, and each individual image will have an Unique ImageID.
And I plan to store all the image paths in one table.


ImageSetId - ImageID - ImagePath
001 - 001 - C:\Pictures
001 - 002 - C:\Pictures
002 - 001 - C:\Pictures
002 - 002 - C:\Pictures
002 - 003 - C:\Pictures

Now, am I wondering.. Am I able to Have a unique ImageID, relating to the ImageSetID?
But, while still using the same ImageID, but for a different ImageSetID..

The way I plan to use input the data, is by creating a new order, then importing images into that order, but for the ImageSetID to stay the same while I am in the same order, but for the ImageID to change.

If that is not possible, any there any suggestions to how to set that up?

Anything would be appreciated, thank you.

You can make composite key on ImageSetId & ImageID. It will solved your problem.

Combination of both fields will be trated as unique.


Try to establish a composit key using keys specified as suggested in the previous post.

If you still have any doubts ,please do post back.
