<In> operator not working for external content type GetListItems

Sep 18, 2013 at 3:39 PM
I'm working in SP2010, and trying to query an external content type list. I'm using the<In> operator, but it doesn't seem to be working right. Lost the error now, but if necessary I can go code something up to reproduce. Have had to just do away with that query for now.

Any ideas? :)

Isn't the IN operator something that was added into CAML in 2010, i.e., it wasn't in 2007? AFAIK, they didn't update any of the existing SOAP Web Services.

Can you share your code? And does IN work for you with regular lists?

I'm having an issue with <In> clause as well. Could you please clarify the difference between a regular list and an external content type list?

Can you share your code? External Lists are those which work with data outside of SharePoint. Read about it here:
