Pass .csv file as parameter file for expdp Oracle 11.2.0.4.0
No you cannot.  I'm not entirely sure what you are after here - I'm assuming that you want to unload a table in CSV format ?  If that's the case, then an easy way would be to download sqcl

http://www.oracle.com/technetwork/developer-tools/sqlcl/downloads/index.html

It's free and small (10mb), and then its just a case of running a query against your table

SQL&gt; spool my_output_file.dat
SQL&gt; select /*csv*/ * from scott.emp;
