Hive 配置单元等价于sql更新

我正在尝试将下面的查询转换为等效于配置单元的查询

正在更新rpt表中的tier_cd，但配置单元0.13不支持更新，因此使用更改为配置单元等效项和输出是不正确的

UPDATE test_report A 
SET TIER_CD = (SELECT B.TIER_CD FROM lk  B
WHERE B.CLASS_CD = A.CLASS_CD AND B.RC_TYPE_CD = 'OATS' 
AND A.ACPTD_ROE_CT >= B.BEGIN_QT 
AND A.ACPTD_ROE_CT <= B.END_QT
AND EFCTV_DT = (SELECT MAX(C.EFCTV_DT) FROM LK C WHERE 
C.CLASS_CD = B.CLASS_CD AND C.RC_TYPE_CD = 'OATS' AND 
C.TIER_CD = B.TIER_CD AND
C.EFCTV_DT <= ?
AND B.TIER_CD <> 'I')
WHERE A.YEAR_CD = ?
AND A.MONTH_CD = ?;

蜂巢当量如下

select z.*,x.tier_Cd from
(
select * from test_report
where year_Cd=?
and month_Cd=?')z
left outer join
(SELECT B.TIER_CD TIER_cD, A.MKT_CLASS_CD,A.year_cd FROM LK B, test_report A
WHERE B.CLASS_CD = A.CLASS_CD AND B.RC_TYPE_CD = 'OATS' 
AND A.ACPTD_ROE_CT >= B.BEGIN_QT 
AND A.ACPTD_ROE_CT <= B.END_QT
AND EFCTV_DT = (SELECT MAX(C.EFCTV_DT) FROM LK C WHERE 
C.CLASS_CD = B.CLASS_CD AND C.RC_TYPE_CD = 'OATS' AND 
C.TIER_CD = B.TIER_CD AND
C.EFCTV_DT <= ?)  
AND B.TIER_CD <> 'I')x
on(z.class_Cd=x.Class_Cd)

请帮助解决问题。

Hive不支持多个子查询，相反，您可以仅使用联接连接三个表。我猜你在select max附近出错了
