I was trying to figure out how to use the nested query pattern for querying JSON with a variable.\r\nI have tried :\r\n\r\nip_val = \"Person\"\r\nres2 = [   select (l)\r\n        match {\r\n              \"iri\": {\r\n                      \"value\": as l\r\n                     },\r\n              \"label\": {\r\n                  \"value\": ip_val\r\n              }\r\n        } as x in ip_json ]\r\n\r\nHere I am trying to substitute variable \"ip_val\" in query under label tag.\r\nI also tried using \"for\"  and let\". Can you please guide me for this?\r\n\r\n\r\nPS: I thought this would be a faster way to reach out to you. :)","author":{"url":"https://github.com/nikhilg1312","@type":"Person","name":"nikhilg1312"},"datePublished":"2020-02-01T14:56:10.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/17/pythonql/issues/17"}
