Tables with no Primary Key

Question

I have several tables whose only unique data is a uniqueidentifier (a Guid) column. Because guids are non-sequential (and they\'re client-side generated so I can\'t use news

Answer 1

Since you are doing replication, your are correct identities are something to stear clear of. I would make your GUID a primary key but nonclustered since you can't use newsequentialid. That stikes me as your best course. If you don't make it a PK but put a unique index on it, sooner or later that may cause people who maintain the system to not understand the FK relationships properly introducing bugs.
