RE: Executing a query for the output without doing the SQLNet round trips

Is the option to put the query in a job, which you schedule? A job always runs 
in de serversite and will not give round trips.

Hemant,

If put an your query as inline view and do a count on non-indexed column, then 
you will be able to all the physical/logical IO and table accces (full or by 
rowid via index) in your query and can avoid SQL*Net round trips. If this what 
you are after?

eg.

select COUNT(non-indexed-column)
from (
           your query
       );

That could reduce the number of round-trips yes.  But I am doing a
local (BEQ) connection. Also, I really want to eliminate all
round-trips but still have Oracle fetch all the rows and columns.
