Filter query for startwith/contains doesn't work with not.

[keshavsahuzellis]

Below query are not working.
?$filter=not startswith(FieldName,'XX')
?$filter=startswith(FieldName,'XX') eq true
?$filter=not contains(FieldName,'XX')

I tested the query functions with my test data model. Unfortunately, I got the expected results.
In general, it can be expected that the sum of the number of results for not startswith and startswith is the same as the overall number of results. So e.g.:
AdministrativeDivisions/$count?$filter=not startswith(DivisionCode,'BE') plus
AdministrativeDivisions/$count?$filter=startswith(DivisionCode,'BE' should be the same as AdministrativeDivisions/$count. This holds true as long as the property does not contain NULL values. To my understanding, based on 5.1.1.1.9 Not, OData requires the same behavior for NULL values as SQL, they are ignored.

To have a deep er look at your problem, I would need to have some more details:

• Do you get an exception? And is so, which one?
• In case only some results are missing, do you have an idea what the differences are?
• Can you provide the generated SQL?
