You can use UTL_FILE in append mode.

Subject: Spooling SQL*Plus output to a unique file name (Unix)

Oracle 7.3.4, Dynix 4.2.3, SQL*Plus 3.3.4, PL/SQL 2.3.4

I have a PL/SQL script that I am running on the server (Unix) and I am spooling the output into a log file. The problem is that I don't want to lose the previous output each time I run the script, so I want to be able to either spool to a unique file name each time (e.g. by appending a timestamp or the process ID or something to the log file name), or keep the same file name but *append* the new output to the old instead of overwriting everything each time.

I have read the SQL*Plus documentation on the SPOOL command and don't see any options for appending output to an existing file instead of overwriting, so I'm guessing that's not possible...

So, I guess I am looking to do something like:

DECLARE unique_file_name VARCHAR2(18);
...
BEGIN
...

   SELECT to_char(sysdate,'YYYYMMDDHHMISS')||'.log'    INTO unique_file_name
   FROM dual;
...

   SPOOL unique_file_name
...

   SPOOL OFF
END; But, this doesn't work because Oracle doesn't like the SPOOL statements within the PL/SQL block, but if I take them out of the PL/SQL block, I get a log file called unique_file_name.lst rather than 20000501103013.log (or whatever).

I'm probably missing something stupid here, but can't seem to get any further...

Thanks very much for any ideas,
Patricia
