Obtenga claves Json en un MySQL para un valor particular

Como dije, puede ser un desafío analizar JSON en MySQL ya que aquí se trata de claves basadas en texto.
Entonces necesitaría usar JSON_KEYS() para obtenerlos en combinación con un generador de números, se genera una ruta JSON dinámica para usar en JSON_EXTRACT()

Función 8 de MySQL JSON_TABLE() hace que sea mucho más fácil..
