Hello all

I have a sql file that I want execute by using the cmdsql command line. But when I create a text file I receive two Informational Messages:

1."Changed database context to 'DataBaseName'."

2.(2 row(s) affected)

How can I ignore these messages in my text file? there is a parametter or something elese to configure to avoir these Informational Messages?
