Subj:   Which method is faster?
From:   Kunnath, Sidharth


Is selecting data using the distinct clause faster than using a group by clause?

Consider these queries as examples

     Select c3, c4 from temp1
     Group by 1, 2

     Select distinct c3, c4 from temp1

Also (c3, c4) are not PI.

Thanks & Regards,

Sidharth Kunnath,
