bat or cmd file to

Hi,

I want to log in to my DB serer through .bat or .cmd file and run the script as well.
e.g.
sqlplus uid/pass@DB
select sysdate from dual

Here the script should connect to the DB server and should return me the sysdate as well.

However, currently it is taking me to SQL prompt and forcing me to type the queries over there.

Any help would be appreciated.
