ORDER BY gives good performance or INDEX hint gives good performance.

ramya_162Sep 8 2014 — edited Sep 8 2014

Hi Experts,

ORDER BY DESDC is better (or) INDESX_DESC hint is better in terms of performance?

Out of the below 2 queries which query is better?

SELECT * FROM big_table WHERE SOD_ID = 22 ORDER BY sname DESC;

CREATE INDEX sname_idx ON big_table(sname);

SELECT /*+ INDEX_DESC(bigtable sname_idx) */ * FROM big_table WHERE SOD_ID = 22;

Please help me.

Thanks.
