Msg 102, Level 15, state 1 Line 1 Incorrect syntax near 'n'

I have the following query which I am running using a batch file. In the batch file I use the following syntax:

echo populating Application table with values...

SET "installFile=%sqlDir%\Install\DataFiles\Insert_ApplicationNames.sql"

OSQL /n /i "%installFile%" /d%db% /U%user% /P%pswd% /S%serv%
echo
echo populated Application table with values in Insert_ApplicationNames.sql
echo

The sql shown below runs without any errors when executed from the SQL Management Studio, but it keeps erroring out when run as a part of the batch script. Could some one help me find what I may be doing wrong here?

Also, the rows do get inserted, but our nightly QA install breaks because of the error thrown by the batch script.

IF NOT EXISTS(SELECT * FROM Application WHERE name = '')
BEGIN
    INSERT INTO Application
    (Name)
    VALUES
    ('')
END
GO
IF NOT EXISTS(SELECT * FROM Application WHERE name = 'Ap开发者_JAVA技巧p1.exe')
BEGIN
    INSERT INTO Application
    (Name)
    VALUES
    ('App1.exe')
END
GO
IF NOT EXISTS(SELECT * FROM Application WHERE name = 'App2.exe')
BEGIN
    INSERT INTO Application
    (Name)
    VALUES
    ('App2.exe')
END

GO is the (default) batch separator keyword in Management Studio, but it isn't a real SQL keyword (i.e., SQL Server doesn't recognize it).

Remove those from your script -- in the script you've provided, they are irrelevant anyway -- and you should be good to, um, go.

Curious whether your variables should be right up against the switches. Try this?

OSQL -n -i "%installFile%" -d %db% -U %user% -P %pswd% -S %serv%

What happens when you use the line above with your known good values right in the command?

OSQL -n -i "C:\foo.sql" -d MyDB -U MyUser -P MyPwd -S MyServ
