  I have a question here.  

  If UPI is defined on 5 columns, what if only 1 or 2 columns are used in the where condition, will the query takes advantage of UPI in this case?  

  Or all the 5 columns needs to be used in the where condition everytime?  

Hi Sravan,

If your index is partially qualified, system will go for FTS.
