how to get only odata count without value

[chentopf]

Is there any way I can get only count of the data in response payload without any value array?

I just need something like "@odata.count":1, "value":[] or without "value".

I tried $count=true&$top=0
or Projects/count

as I saw on some blogs.
But it didn't work

Please assist...

The right way would be Projects/$count.
Without the $ its not an OData function and is ignored.

@chentopf, did you get it working?

Mine not, getting error <message>Error occurred validating the Criteria</message>

[chentopf]

Yes it is working for me

[Falseclock]

That is strange, cause getting error "No criteria query roots were specified" on this line from

olingo-jpa-processor-v4/jpa/odata-jpa-processor/src/main/java/com/sap/olingo/jpa/processor/core/query/JPAJoinQuery.java

Line 71 in 5873bd2

return em.createQuery(cq).getSingleResult();

I ran an example locally with EclipseLink as JPA implementation and it worked fine. Do you use Hibernate?

[Falseclock]

@wog48, yes, v5.2.14

There is an error in the code. To be honest it is unclear to me why EclipseLink works fine. I will provide a fix.

[wog48]

The fix is part of latest release 0.2.7.

Thanks!
when do you plan to add it to maven repository?
