If you can choose,  you should use PowerShell instead of a cmd batch file. With a traditional batch file you need to run sqlplus with formatting settings in sqlplus, then parse the resulting text. With PowerShell you can run commands against Oracle via ADO.NET, and directly access results, doing whatever you want to do with it.

why would you use powershell or the command line

get a programming tool, create an exe and use that exe
there is even some programming environments free
like perl

since you need to start from scratch anyway ... take the more advanced step immediately
Geert GOracle dbaCommented:
but, if you really want to do it from the command line

download and install oracle client, the runtime version
from downloads ... it's free

sqlplus user/password@database @yourscript.sql

Open in new window

in yourscript.sql:
spool outputfile.txt
select yourquery;
spool off

Open in new window

Of course the code Geert posted is too primitive to really be useful in a batch, but it shows some of the basics

Geert, never question the use of PowerShell :D.
It is a semi-interpretative programming language, generating P-Code as any other .NET language does too. But it is much more flexible when having to apply changes. Nevertheless, using a custom EXE is an option if there are no changes, and always the same process to be run.

a custom EXE is also an option if there are changes ... :)
