Oracle csv line size more than 32767
You can't use utl_file, since it has a maximum line length of 32767.
It's possible that sqlplus has a similar limit. If you are tying to 
move data to a different Oracle database you can use data pump. You 
can eve use datapump on a materialized view. If you want to migrate 
to a non Oracle database you can use Perl or heterogeneous services
to create a database connection to mySQL, SQL Server, etc. Then you
won't have to worry about the line length.
