Filter an OData query based on a link count? -


Given a framework where two types have appeared in an Odata system with a master / extension relationship:

Order
- Order Details

How would you filter a query based on the count of related order details? In my head, this is something with lines of

/ order $ filter = count (OrderDetails) eq 0

but surely no count Not working. So, how do you prepare a list of orders that do not have any orders?

Very similar question for this one: Currently the Odita Protocol does not have any operator / Does not support the query. The best solution is to expose a service operation that directly displays such operation from the server.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
