我是 hive 新手,我想实现以下查询
select a.controlid,
b.name as campaign,
a.controlactivityid as activitysource,
c.code as codemyaprc,
c.label_en as label_en,
c.label_fr as label_fr
from bo_h_control.bridgeactivity a
join suvh_econtrol.TMP_GPS_REF b ON a.controlcampaignid =
b.ps_cam_id
left join srv_h_a8460_fpc.activity c
ON a.controlactivityid=c.code
and c.date_creation= select
max(date_creation) from srv_h_a8460_fpc.activity
在最后一个左连接之前它工作正常。嵌套查询显然没有在 hive 中授权。
我该如何解决这个问题。
