Hi,

Short of Redgate Data Compare, check this out for generating Tablediff command lines...has saved my bacon a few times, and is surprisingly quick.

(I've got Red Gate tools (which are cool!), but can't install them on isolated customer boxes on the other side of restrictive VPNs or DMZ's - whereas Tablediff ships with all 2008+ sql)
