Subj:   Re: Creating tables 50% to 90% of columns as unique primary index

  Does a hand-coded Atomic Upsert look a little like Mighty Mouse? P'haps an example would be better.  

Frank, I think what Robert meant was the proper UPSERT, not a combination of two separate statements, INSERT + UPDATE. NCR had coined the word 'atomic' to emphasize that with UPSERT Teradata needs to make a single pass to perform two actions.

When I heard the word for the first time I thought they were referring to the requirement to specify all PI columns in the WHERE clause but no.
