Reddy, Thanx for information , i know that the results will be put in a PLAN_TABLE.
When you select * from PLAN_TABLE depending on which column will u able to decide the query is ok.
One thing is depending on index usage.
Second there are two cost columns PROCMS and PROCSU.
Do you know the maximum possible values for the above two columns,so that we can able to tell the query is performing well.
