I have a table which is containing 20900000 records. Now pertaining to some joining condtions this table return around
400000 records.

Now these records are utilized by a report. This report takes 3-4 hours for reading almost 400000 records

We tried using pipe row clause so that the report start processing records as soon as it gets some records. Also tried to use bulk collect.


But it is not helping to a good extent. Please advice

You have about 21M records. IMHO - 3-4 hours to process that data is too much even using FULL table scan.
Probably your report performs some additional processing as well.
