Re: create a view with parallel hint

Tony

I believe that you'll need to be using a native and not an odbc connection
to get the hints to be recognised. (Crystal used to allow for native/oledb
and odbc connections and only the native connection was any good really)
note I haven't looked at it for 2 years.
