JSONArray轉多行JSON

先通過explode把原數據變成n行數據，然後再用get_json_object去解析

select ss.json_col
from (
       select split(regexp_replace(regexp_extract('需要解析的jsonArray', '^\\[(.+)\\]$',1)
              ,'\\}\\,\\{', '\\}\\|\\|\\{'), '\\|\\|') as json_str
       from json_array_table
      ) pp
lateral view explode(pp.json_str) ss as json_col;

 實例:

select ss.json_col
from (
       select split(regexp_replace(regexp_extract('[{"time":1582487998465,"_track_id":1358410713,"event":"joyLinkClick","_flush_time":1582488009148,"distinct_id":"6342133","properties":{"$os_version":"12.4.5","$device_id":"FCF68CFD-1F1A-4C2C-BA67-AD556C4EB125","app_name":"查悅社保","$carrier":"中國移動","$os":"iOS","$screen_height":640,"$is_first_day":false,"$screen_width":360,"$model":"iPhone7,1","$lib":"iOS","$network_type":"WIFI","$app_version":"3.4.3","$manufacturer":"Apple","$wifi":true,"jtrack_page":"服務","jtrack_name":"服務","$lib_version":"1.10.21"},"type":"track","lib":{"$lib_version":"1.10.21","$lib":"iOS","$app_version":"3.4.3","$lib_method":"code"}},{"time":1582487998507,"_track_id":957323951,"event":"joyLinkClick","_flush_time":1582488009149,"distinct_id":"6342133","properties":{"$os_version":"12.4.5","$device_id":"FCF68CFD-1F1A-4C2C-BA67-AD556C4EB125","app_name":"查悅社保","$carrier":"中國移動","$os":"iOS","$screen_height":640,"$is_first_day":false,"$screen_width":360,"$model":"iPhone7,1","$lib":"iOS","$network_type":"WIFI","$app_version":"3.4.3","$manufacturer":"Apple","$wifi":true,"jtrack_page":"社保","jtrack_name":"社保","$lib_version":"1.10.21"},"type":"track","lib":{"$lib_version":"1.10.21","$lib":"iOS","$app_version":"3.4.3","$lib_method":"code"}},{"time":1582487998572,"_track_id":535356242,"event":"$AppClick","_flush_time":1582488009151,"distinct_id":"6342133","properties":{"$os_version":"12.4.5","$element_content":"服務","$device_id":"FCF68CFD-1F1A-4C2C-BA67-AD556C4EB125","app_name":"查悅社保","$carrier":"中國移動","$os":"iOS","$screen_height":640,"$is_first_day":false,"$screen_width":360,"$model":"iPhone7,1","$lib":"iOS","$network_type":"WIFI","$app_version":"3.4.3","$manufacturer":"Apple","$wifi":true,"$screen_name":"JOYServiceController","$element_type":"UIControl","$lib_version":"1.10.21"},"type":"track","lib":{"$lib_detail":"JOYServiceController######","$lib_version":"1.10.21","$lib":"iOS","$app_version":"3.4.3","$lib_method":"code"}},{"time":1582487998616,"_track_id":2696301578,"event":"$AppViewScreen","_flush_time":1582488009152,"distinct_id":"6342133","properties":{"$os_version":"12.4.5","$device_id":"FCF68CFD-1F1A-4C2C-BA67-AD556C4EB125","app_name":"查悅社保","$carrier":"中國移動","$os":"iOS","$screen_height":640,"$is_first_day":false,"$screen_width":360,"$model":"iPhone7,1","$lib":"iOS","$network_type":"WIFI","$app_version":"3.4.3","$manufacturer":"Apple","$wifi":true,"$screen_name":"JOYServiceController","$lib_version":"1.10.21"},"type":"track","lib":{"$lib_detail":"JOYServiceController######","$lib_version":"1.10.21","$lib":"iOS","$app_version":"3.4.3","$lib_method":"code"}},{"time":1582488001012,"_track_id":149863720,"event":"joyLinkClick","_flush_time":1582488009153,"distinct_id":"6342133","properties":{"$os_version":"12.4.5","$device_id":"FCF68CFD-1F1A-4C2C-BA67-AD556C4EB125","app_name":"查悅社保","$carrier":"中國移動","$os":"iOS","$screen_height":640,"$is_first_day":false,"$screen_width":360,"$model":"iPhone7,1","$lib":"iOS","$network_type":"WIFI","$app_version":"3.4.3","$manufacturer":"Apple","$wifi":true,"jtrack_page":"課程","jtrack_name":"課程","$lib_version":"1.10.21"},"type":"track","lib":{"$lib_version":"1.10.21","$lib":"iOS","$app_version":"3.4.3","$lib_method":"code"}},{"time":1582488001061,"_track_id":563548821,"event":"$AppClick","_flush_time":1582488009154,"distinct_id":"6342133","properties":{"$os_version":"12.4.5","$element_content":"課程","$device_id":"FCF68CFD-1F1A-4C2C-BA67-AD556C4EB125","app_name":"查悅社保","$carrier":"中國移動","$os":"iOS","$screen_height":640,"$is_first_day":false,"$screen_width":360,"$model":"iPhone7,1","$lib":"iOS","$network_type":"WIFI","$app_version":"3.4.3","$manufacturer":"Apple","$wifi":true,"$screen_name":"JOYServiceController","$element_type":"UIControl","$lib_version":"1.10.21"},"type":"track","lib":{"$lib_detail":"JOYServiceController######","$lib_version":"1.10.21","$lib":"iOS","$app_version":"3.4.3","$lib_method":"code"}},{"time":1582488001609,"_track_id":977721946,"event":"$AppViewScreen","_flush_time":1582488009155,"distinct_id":"6342133","properties":{"$os_version":"12.4.5","$device_id":"FCF68CFD-1F1A-4C2C-BA67-AD556C4EB125","app_name":"查悅社保","$carrier":"中國移動","$os":"iOS","$screen_height":640,"$is_first_day":false,"$screen_width":360,"$model":"iPhone7,1","$lib":"iOS","$network_type":"WIFI","$app_version":"3.4.3","$manufacturer":"Apple","$wifi":true,"$screen_name":"WebViewController","$lib_version":"1.10.21"},"type":"track","lib":{"$lib_detail":"WebViewController######","$lib_version":"1.10.21","$lib":"iOS","$app_version":"3.4.3","$lib_method":"code"}},{"time":1582488003641,"_track_id":984325331,"event":"$AppViewScreen","_flush_time":1582488009155,"distinct_id":"6342133","properties":{"$os_version":"12.4.5","$device_id":"FCF68CFD-1F1A-4C2C-BA67-AD556C4EB125","app_name":"查悅社保","$carrier":"中國移動","$os":"iOS","$screen_height":640,"$is_first_day":false,"$screen_width":360,"$model":"iPhone7,1","$lib":"iOS","$network_type":"WIFI","$app_version":"3.4.3","$manufacturer":"Apple","$wifi":true,"$screen_nam
