Probabilmente scriverei lo script (o il condizionale, a seconda dei requisiti) dal chiamato script.sql stesso.
Ad esempio, il seguente script.sql crea un file .bat windows_commands.bat :
set feedback off
set echo off
set trimspool on
set termout off
set serveroutput on size 100000 format wrapped
set lines 500
set pages 0
-- create the bat file to be executed later:
spool windows_commands.bat
declare
c number;
begin
select count(*) into c from dual;
-- depending on a conditional, write the stuff to be executed into the
-- bat file (windows_commands.bat)
if c = 1 then
dbms_output.put_line('@echo everthing ok with dual');
else
dbms_output.put_line('@echo something terribly wrong with dual');
end if;
end;
/
spool off
exit
Puoi quindi chiamare script.sql da un altro file .bat così:
@rem create oracle session, call script.sql
sqlplus %user%/%password%@%db% @script.sql
@rem script.sql has created windows_commands.bat.
@rem call this newly created bat file:
call windows_commands.bat
