Answer 2

I do something like this by creating a .bat file which does the windows stuff and calling sql scripts as needed. Use SQL to spool your results to a text file which you can read.

...dos commands here

sqlplus /nolog @C:\Dump\DropRecreateUsers.sql

sqlplus /nolog @C:\Dump\Cleanup.sql

...dos commands

In the sql use this command spool C:\yourResults.txt or for more sophisticated usages create a procedure, which, when called, writes the results to a text file using UTL_FILE

I would strongly encourage you to not use .bat files. You've got lots of other alternatives: C/C++ or VB, Windows scripting or Powershell, or even free downloads like Perl or Bash.

But here's one example of returning error codes in .bat files:

But please do look at some of the links I gave above. Avoiding .bat files will make it easier for you, and make it easier to maintain in the future.

I encourage you to take a look at the two scripts included in the Oracle XE for backup and restore. These scripts have taught me a lot how to handle batch-scripting and Oracle on the Windows platform.

• C:\oraclexe\app\oracle\product\11.2.0\server\bin\Backup.bat
• C:\oraclexe\app\oracle\product\11.2.0\server\bin\Restore.bat

Answer 5

This is what I ended up using.

My .cmd script:

@ECHO OFF
ECHO Checking Oracle...

for /f %%i in ('sqlplus -s user/password@database @script.sql') do @set count=%%i
echo %count%

IF %count% GTR 0 GOTO :skipped
GOTO :runprocess

Where script.sql:

SELECT COUNT(*)
FROM table
WHERE criteria = 1;

exit

Answer 6

I'd probably write the script (or the conditional, depending on the requirements) from the called script.sql itself.

For example, the following script.sql creates a .bat file 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

You can then call script.sql from yet another .bat file like so:

@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
