Subj:   Multi-column statistics

Hi all,

I've been told by the project teradata expert that multi-column statistics are never necessary. "It is enough to collect stats on each individual column".

Is this so? I've read otherwise in the documentation.

What would be a good example of multi-column stats being necessary?


Cheers

Anomy
