GraphQL is not OData¶

https://jeffhandley.com/2018-09-13/graphql-is-not-odata

GraphQL is not OData. Can we please stop casting OData’s flaws onto GraphQL? At Microsoft, I used and propagated OData against my own judgment. I’m sorry I couldn’t stop the train wreck. At Concur, we successfully employ GraphQL over top of RESTful APIs. Feel free to @ me. — Jeff Handley (@JeffHandley) August 29, 2018

Note¶

ABAP Serializer and Deserializer¶

https://wechris.github.io/tips-tutorials/sap/abap/json/2018/02/12/ABAP-to-JSON-and-JSON-to-ABAP/

* serialize table lt_flight into JSON, skipping initial fields and converting ABAP field names into camelCase
    LV_JSON = /UI2/CL_JSON=>SERIALIZE( DATA = LT_FLIGHT COMPRESS = ABAP_TRUE PRETTY_NAME = /UI2/CL_JSON=>PRETTY_MODE-CAMEL_CASE ).

    " Display JSON in ABAP
    CALL TRANSFORMATION SJSON2HTML SOURCE XML LV_JSON
                               RESULT XML DATA(LVC_HTML).
    CL_ABAP_BROWSER=>SHOW_HTML( TITLE = 'ABAP (iTab) -> JSON: /ui2/cl_json=>serialize' HTML_STRING = CL_ABAP_CODEPAGE=>CONVERT_FROM( LVC_HTML ) ).

    CLEAR LT_FLIGHT.

* deserialize JSON string json into internal table lt_flight doing camelCase to ABAP like field name mapping
    /UI2/CL_JSON=>DESERIALIZE( EXPORTING JSON = LV_JSON PRETTY_NAME = /UI2/CL_JSON=>PRETTY_MODE-CAMEL_CASE CHANGING DATA = LT_FLIGHT ).
