iot - Not able to filter messages based on header properties in Azure Stream analytics -


i have created azure stream analytics (asa) job filter data based on custom header property send client app.

how read/filter message header properties in azure stream analytics? portal return no results when try test out query. below query in azure portal.

so far query simple this:

select     *     [mystorage]     [iothubin]  properties.type = "type1"

i tried call out key without parent (such as: type = "") no results well.

i sure sending messages custom property in header since can view using device explorer tool.

any idea how working?

i haven't tried yet myself, supposedly can access custom properties via getmetadatapropertyvalue(). give try:
