RE: Access
Do you want to create a relationship between tables or queries. Both are possible.
The simple answer is to drag one of the fields from the one field list in a query to the one you want to link to.
You can do this in the RELATIONSHIPS window, which you can find under TOOLS > RELATIONSHIPS.
You can also do it in the top window when you are designing a query.
Does that answer your question?
