Thanks..
But I guess, you still didn't understood me properly...

Thnks again..
>IMHO, I think there should be a way to retreive the information you need if you have all the unique keys that are necessary in your tables to identify the relations.
>In your contact example you can do it even if you don't merge tables by adding a key like :

>
>table NAME
>fields : code, name
>record1: 1, claude
>record2: 3, Rocky
>
>table ADDRESS
>fields : code, contact_id, address
>record1 : 1, 22, Montreal
>record2 : 1, 55, Toronto
>record3 : 3, 13, Toronto
>
>table CONTACT
>fields : code, contact_id, phone
>record1 : 1, 22, 555-5555
>record2 : 1, 55, 666-6666
>record3 : 3, 13, 666-6666
>
>and then
>
>SELECT * FROM NAME, ADDRESS, CONTACT;
> WHERE NAME.CODE=ADDRESS.CODE AND ADDRESS.CONTACT_ID=CONTACT.CONTACT_ID
