Database design - defining a basic many-to-one relationship -

-

this basic database design question. want table (or multiple tables) defining relationships between customers. want primarycustomer can linked multiple secondarycustomers, , can have many secondarycustomers same relationship.

primarycustomerid  relationshipid  secondarycustomerid

1) if primary key {primarycustomerid} can have 1 linked customer of kind.

2) if primary key {primarycustomerid, relationshipid}, can have 1 linked customer each relationship type.

3) if primary key {primarycustomerid, relationshipid, secondarycustomerid}, can have whatever like, having columns primary key seems wrong.

what's right way set things up?

number 3 right way go data model. linking tables have columns in join link other tables.
