Cetin,

What sort of problems/headaches have you encountered with integers? What I really store in my primary key fields are the integers returned by a GetLastNumber() routine then converted to zero padded character strings.

Would'nt the use of GUID values as primary key values eat up a lot of disk space? That's already a 36 character field.

Thanks!

Dennis
