Changing Database Within A Stored Procedure

I need to create a stored procedure in the master database that can
access info to dynamically create a view in another database. It
doesn't seem like it should be very hard, but I can't get it to work.
Here's an example of what I want to do.

CREATE PROCEDURE create_view @dbname sysname
AS
BEGIN
DECLARE @query varchar(1000)
SELECT @query = 'use ' + @dbname + ' go CREATE VIEW ........'
EXEC(@query)
END

In this case, I get an error with the word "go". Without it, I get a
"CREATE VIEW must be the first statement in a batch" error. I tried a
semicolon in place of "GO" but that didn't help either.

Thanks
