Subj:   How DISTINCT and GROUP BY have same performance in TD 14
 
From:   sughesh iyyani

Hi Experts,

Kindly let me know how DISTINCT and GROUP BY have same performance in Teradata 14 ?

How this achieved?

We know DISTINCT will always go for a full table scan.

Kindly advise me.


Thanks in advance,

Sughesh I S.
