I love these external tables. It really gets rid of the old
UTL_FILE.GET_LINE.

Anyhow, is there a way to create an external table where the filename
is dynamic? Basically the filename changes a couple of times during
the process.......

Not sure if this can be done short of re-creating the table, but I
thought I'd ask.....

Regards & Thanks!

To answer that question: no. And why does the file name change 'a
couple of times during the process...'? It would be logical to me to
create a different external table for each file and drop the previous
external table when it is no longer needed.

which does the OP no good. You are correct, however (and I stand
corrected) that in 10g and later releases one can alter an external

SQL> spool off

Which, of course, doesn't make the file name dynamic.
