Dennis,

In reading the question once again it appears that Ayyappan is asking if he an set which partition of the table will be queried in a specific session.

Ayyappan,

Obviously the answer is NO. Partitioning does not limit the amount of data a session can see, but rather the amount of data that the database can ignore when running a query. Now inside the query you can specify what partition to use if you desire. The syntax of which is:

select <column_name(s)>
from <owner>.<table_name> partition(<partition_name>) where <your where clause stuff>

Ayyappan - I'm just trying to understand your question. Pardon me if I'm a little slow, it is Monday. Okay, you have a partitioned table. That is a physical object, nothing to do with the session. And then you query that partitioned table. Is your question how the query will be optimized by certain sessions? A little more information might be helpful on Monday. Thanks.
