  • 找第一层:
SELECT * FROM tourists WHERE json_data->'$.weixinOpenId' = '299485886686868'
或者
SELECT * FROM devices WHERE JSON_EXTRACT(json_data, "$.lcswAccessToken") = '33e5028835bf4d478ed5cd8f8a618ea5'

   

  • 找多层:
SELECT * FROM devices WHERE json_extract(json_extract(json_extract(json_data,"$.lastOperation"),"$.target"),"$.name") = '西门门岗闸机01'
