Subj:   Joins and hash
 
From:   Vijay R. K.

Hello all,

I was reading some documentation that Teradata joins two columns on their has values rather than the values themselves. How true is this? If this is true, since NCR does not rule out hash collision, cant this not result in faulty match of data values?

Please correct me if I'm wrong


Thanks

VRK
