Subj:   PI on multicolumns?
 
From:   Bodla, Sravan Kumar

What is the advantage of defining PI on more than 2 columns?? I understand, for even data distribution the PI should be unique and should be defined only on single column.

But I see many tables in my environment, with PI defined on 4-5 columns and more.

Can you please share your thoughts on the advantages and disadvantages on this and the data distribution on amps and accessibility of data in such cases.


Best Regards,
