may help you . Assemble a dynamic WHERE clause. Start with the function module RH_DYNAMIC_WHERE_BUILD. Write an own string builder if it doesn’t fit.
You could also build ranges for dynamic IN clauses but this would be harder. The field types vary and as ranges are type-specific (TYPE RANGE OF ) you will end up with a lot of over-dynamic code that is no fun programming.

hop of those help? I have a query which appears to be working fine, but I'm wondering if there is a cleaner (or more proper) way to write it. , You could try
code :
SELECT foo bar baz
  FROM ZVBAPIUSW01 UP TO 1 ROWS
  INTO (l_foo, l_bar, l_baz)
  WHERE OBJID = ID
  ORDER BY updpass DESCENDING updpasstime DESCENDING.

I hope this helps . You are trying to place multiple comments at the same position within a single line (BEGIN OF LINE ... END OF LINE block), and you are adding multiple parameters to that single line without specifying positions.

may help you . Is there a way to convert a database query result to json/yaml/xml with ABAP?
code :
    DATA: lt_flight TYPE STANDARD TABLE OF sflight,
          lrf_descr TYPE REF TO cl_abap_typedescr,
          lv_json   TYPE string.

        SELECT * FROM sflight INTO TABLE lt_flight.

        * 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 ).
        WRITE / lv_json.

        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 ).

* serialize ABAP object into JSON string
lrf_descr = cl_abap_typedescr=>describe_by_data( lt_flight ).
lv_json = /ui2/cl_json=>serialize( lrf_descr ).
WRITE / lv_json.
