    I thought that openrowset would not accept a variable parameter

    I have been using sql since the dawn of sql. And I still am not clear on creating bcp format files. I have to do them by hand. The utility seems ok, but no thanks. All I want is something that says: declare @servername nvarchar(50) declare @databasename nvarchar(50) declare @tablename nvarchar(50) declare @filename nvarchar(50) declare @connectiontype nvarchar(50) doit (bpc ---- @variables above. Why can't this be done?
