Hi all,
I have two database schemas.
one is dev and another one is QA.
Both database's version : 11.2.0.3.0
If i run a explain plan for query in dev, it gives cost 231.
But, same query im using in QA, it gives cost 24642.
I have checked the indexes in both databases are same only.
Please help me out on this.
Regards,
Fame
