是否可以使OData返回CSV或URL？

Question

I'm new to OData so I'm sorry if this is a bad question, but I fail to find an answer.

I have a bunch of OData tables, and I would like to provide an option for the user to get the data as a CSV-file.

Now I know OData only supports Atom and JSON, but is there any way to make it return a filestream, or a URL?

I was thinking a URL could direct to a REST-service (not OData) that simply returns a filestream, if filestream directly from OData is impossible.

Any thoughts or ideas are appreciated!

I'm not totaly sure why you want to use oData. But oData essentially means to publish any kind of data in JSON/atom standard format - not CSV.

If you have controll over your oData source you could modify an oData Producer to output CSV filestreams instead of JSON/atom files.(But you wouldn't have a real oData feed anymore) You could also set up any oData Consumer (you can find those at odata.org ) to read your oData source and display it as CSV.

If you choose a server side solution(PHP/JSP/ASP etc.) it should be rather simple to loop through the results of a request and add seperators inbetween.
