Hi,

I have program with a select(10 million rows table) whose where clause does not have any key columns, but couple of non key columns. when i run this program(batch) it runs in 3 minutes, when i did explain it says the DB2 cost for this query is 1,500,000 and Access type is nested loop.

What is confusing me the cost / access type and time it took to run. I think it should run much longer then 3 minutes.
it is partitioned tablespace, Will that make a difference in the way it gets the qualifying rows.
