Hi,
I have read couple of articles and thread messages that suggest to use GUID or auto-generated value as primary key.
Does it complicated while doing maintenance of error checking since we don't really know what that primary key value refer to?

Also, if I have alot of 100 tables, then I should have 100 records in my key table?

Thank you
