How to link three tables without Common primary Key

[nebula53]

I need to generate a report from three tables, these tables does not have common primary Key, how can I link them.

[Rabbit]

If these 3 tables have no relation at all, there's no way to link them. It's like saying I have data about cars, clouds, and gravity. How do I link them?

Is there any logic that relates these tables? Without looking at your tables is hard to answer this question.
