How do I get the error level of commands in a pipe in Windows batch programming?

Question

Batch files return the error code of the last command by default.

Is it somehow possible to return the error code of a former command. Most notably, is it possible t

Answer 1

To call tee for entry bat-file, not for single command, and use errorlevel freely, I use trick like this:

if "%1" == "body" goto :body
call %0 body | tee log.txt
goto :eof
:body

set nls_lang=american_america
set HomePath=%~dp0

sqlplus "usr/pwd@tnsname" "@%HomePath%script.sql" 
if errorlevel 1 goto dberror

rem Here I can do something which is dependent on correct finish of script.sql    

:dberror

echo script.sqlerror failed

it separates using tee from calling any commands inside batch.
