If you really want to use SQL Loader then you would need to use something else to get the data from the source database. you can use DBMS_OUTPUT or just write a sql script that would output the data in the format that you want. You can do something like the following

Code:

---

SET ECHO OFF
SET FEEDBACK 0
SET PAGESIZE 0
SET TRIMSPOOL ON
SPOOL /tmp/data.dat
SELECT '"'||col1||'","'||col2||'","'||col3||'","'||coletc||'"'
  FROM your_table
 WHERE col1='ABC';
SPOOL OFF;

---

You would then create a control file yourself telling sql loader how the data is stored, how to load the data what ever you need to happen. You use a sql loader control file just so you don't have to fit everything in at the command line.

you can also do an exp/imp.
