Garret,

>>Forced use of generated PKs

>I think you'll find that's not just a Fox position: I first read about Surrogate Keys in Databased Advisor back in '94 or so.

Nope, this is not the case. Generated PK's are esspecially usefull in xBase because of the deleted records still existing in the table. This only applies to xBase. I don't reject the use of generated keys, but I do reject the FORCED use of them. In a lot of cases the use of them are doubtfull at the least and there are other knowledgable people who reject them when not neccesary. Joe Celko is a great refference for this.

Walter,
