Question : Error-handling if SQLCMD fails in .bat Windows script

Hi guys,
I am currently on WinXP SP2 against SQLEXPRESS 2008.  I have a script that executes a SQL 2008 stored proc that BULK INSERTS a list of fixed-format files from my C: drive into a table.  After each file has been BULK INSERTed into a table, the script also moves the file to a \Processed folder and renames the file by appending the date & time to the filename.

The problem I am having is figuring out how to grab errors from the SQLCMD statement that runs the stored proc.  I want to not perform the copy/rename for a file if that file BULK INSERT fails (i.e. there are primary key violations).  I have tried setting SQLCMD -b -V 1, but ERRORLEVEL stays at 0 even when the stored proc returns primary key violations from the BULK INSERT.

Here is the code I have so far:

::@ECHO OFF

:: Set date/time variables to build and append to the renamed filename
SET DAY=%DATE:~4,2%
SET MTH=%DATE:~7,2%
SET YR=%DATE:~10,4%
SET HR=%TIME:~0,2%
SET HRO=%TIME:~0,1%
IF "%HRO%"==" " SET HR=0%%TIME:~1,1%
SET MIN=%TIME:~3,2%
SET SEC=%TIME:~6,2%
SET STRDATE=%YR%%MTH%%DAY%-%HR%%MIN%%SEC%

::SET ERRORLEVEL=0

:: Set file directories
SET DIRDATA=C:\FIXEDFILEUPLOAD\Data\
SET DIRHIST=C:\FIXEDFILEUPLOAD\Data\Processed\

:: Loop through all .txt files and execute sproc to upload flat file into SQL table
cd %DIRDATA%
for %%i in (*.txt) do sqlcmd -Q "exec dbo.nkn_LoadDataSP '%DIRDATA%%%i'" -U user -P password -S MACHINE\SQLEXPRESS -d DB_TEST & move %DIRDATA%%%i %DIRHIST%  & ren %DIRHIST%%%i %%i.%STRDATE%

I know this is probably easy, but I've been having a tough time on this.

Thanks in advance,

Gome

We could also match with "Msg:" instead of error keywords. That would capture any error and warning message, but not reveal the error message (which is reported in the line following that "header").
