SQL split hexastring dalam byte yang berbeda

#standardSQL
WITH `data.source` AS (
  SELECT 'S,0,2B3,8, C2 B3 00 00 00 00 03 DE' AS frame UNION ALL
  SELECT 'S,0,3FA,6, 00 E0 04 A5 00 0B' UNION ALL
  SELECT 'S,0,440,8, 83 40 4E A5 00 47 00 64' UNION ALL
  SELECT 'S,0,450,8, 84 50 01 12 01 19 01 B3' UNION ALL
  SELECT 'S,0,4B0,8, 84 B0 4E A5 00 43 00 64' 
)
SELECT
  frame, bytes, STRING_AGG(b, ' ' ORDER BY p) AS selected_bytes
FROM (
  SELECT frame, TRIM(SPLIT(frame)[OFFSET(4)]) AS bytes, SUBSTR(TRIM(SPLIT(frame)[OFFSET(4)]), 1, 2) AS f
  FROM `data.source`
  WHERE SUBSTR(TRIM(SPLIT(frame)[OFFSET(4)]), 1, 2) IN ('83', '84')
), UNNEST(SPLIT(bytes, ' ')) AS b WITH OFFSET AS p
WHERE CASE f WHEN '83' THEN p IN (5, 6, 7) WHEN '84' THEN p IN (2, 3, 4) END
GROUP BY frame, bytes
-- ORDER BY frame

hasilnya adalah:

frame                               bytes                       selected_bytes
