SPOOL or UTL_FILE

Question

Hi all,
with the next script I spool an information into a file. Then I update all processed lines with UPDATE-Command.
set echo off
set verify off
set pagesize 0
set termout off
set heading off
set feedback off
spool c:\Temp\test_info.lst
select id||'|'||date||'|'||firname||'|'||secname||'|'||hiredate
||'|'||las
from test
where las is null
spool off
update test
set las = 'x'
commit;
set feedback on
set heading on
set termout on
set pagesize 24
set verify on
set echo on
Now I would like to however only examine, whether spool was successful, and only then to update. How can I do that?
Must I write a PL/SQL-Script with UTL_FILE-Package instead of a SQL*Plus-Script with SPOOL?
But UTL_FILE Package does not fit, because I do not want to permit
to the Client something write on the Server-machine. Or can I store the file on the Client with UTL_FILE Package?
Regards
Leonid

Hi Serge,
I would like updates then only if spool into the file something wrote.
And still another question: can I examine somehow whether the file exists? E.g. if I would write instead of c:\Temp c:\Temp1 (or if drive assembly is full), no file am provided, but the table is nevertheless changed.
