Query using flat file in the FROM Statement

Question

I have a flat file that contains about 10k rows that I need to join to a table with 2million plus rows. My problem is I cannot load the flat file into a Oracle table or create a new table to contain the 10k rows because I lack of permissions to create table on my user account. I have tried using MS-Access to query the two tables using ODBC, but the query times were horribly slow and would time out. I was curious if there is a way of calling the flat file as a table in my SQL statement from Oracle?
I know the following doesn't work but I was wondering if there is something out there that would allow me to do something like the following?
example:
SELECT a.COL1, a.COL2, ff.COLa, FF.COLb
FROM apple a, c:\temp\flat_file.csv ff
WHERE a.COLa=ff.COLa
db version - 10g
OS - Windows XP Pro
Thanks in Advance!

Thanks in Advance!Is there some reason you cannot get the data loaded into the local database?
If you absolutely cannot (either through creating and loading objects, or having someone else do it for you) i would likely recommend installing your own database (Oracle XE is free and will easily handle your flat file)
http://www.oracle.com/technetwork/database/express-edition/downloads/index.html
I would install that, load your data into a schema you create, and then create a database link to the remote database and use that in your query.
I would highly push you to work with the administrators of the database though and get them to set you up a schema where you can create objects (with access to the objects in other schemas that you require, if only read permitted).
