Here is a portion of the code. If comment out the crec.s line and uncomment the Jeff line it works. Crec.s is coming from a table - I know its a horrible column name being selected into.

c_text:= 'A' ||chr(9)||

          crec.b ||chr(9)||
          crec.c ||chr(9)||


             ' ' ||chr(9)||

          crec.t ||chr(9)||


             ' ' ||chr(9)||

          crec.g ||chr(9)||


             ' ' ||chr(9)||

          crec.i ||chr(9)||
          crec.j ||chr(9)||
          crec.k ||chr(9)||


             ' ' ||chr(9)||

             ' ' ||chr(9)||

             ' ' ||chr(9)||

             ' ' ||chr(9)||

             ' ' ||chr(9)||

             ' ' ||chr(9)||

          crec.r ||chr(9)||
          crec.s ||chr(9);
--          'jeffhere' ||chr(9);
 
if c_text is not null then
   dbms_output.put_line(c_text);
 dbms_output.put_line('length'||to_char(length(crec.s)));
 dbms_output.put_line(crec.s);
   utl_file.putf(fhandle,c_text||'\n');

Morning Jeffrey,

>> We are getting the invalid_filehandle error after outputting >> a dozen rows of data.
<SNIP>
>> What conditions would cause this kind of error.

I have to guess here unfortunately (ducks Alex !) as you haven't posted
any code, however, based on my own past experience, it could be caused by :

some data in the new column is causing an exception.
that exception is closing the file handle
the post exception processing is trying to write to the (now closed) file handle.

something in the exception handler is overwriting the file handle when it shouldn't be doing so.

Any chance we can see the before code and after code (or at least the bits that changed) - it might be easier to spot the problem.

Cheers,
Norman.
