我正在尝试将以下teradata sql转换为hive sql但是在结束行附近出现错误：ParseException行83：6丢失）在'qualify'附近'qualify'行83:14错过了'row_number'附近的EOF '资格'
我对蜂巢很新。任何帮助将不胜感激

QUALIFY是专有的Teradata语法，您必须使用派生表重写它：
select customer_id tier_cust_id,
support_segment tier_suppt_seg
from (select c.customer_id,
c.primary_email_name,
am_id,
am_name,
c.customer_first_name ,
c.customer_last_name ,
c.customer_primary_residence ,
c.CUSTOMER_USER_GROUP,
c.customer_flag1,
case when c.customer_primary_residence not in ('US', 'MX', 'CA') then 'ROW'
when ent.cust_id = bam.cust_id then 'Enterprise Support'
when smb.cust_id = bam.cust_id then 'Merchant Support'
when am.am_name like '%Merchant Support'
or am.am_name like '%Business Support'
or am.am_name = 'Sole Proprietor'
then 'Business Support'
else 'Currently Unassigned'
end support_segment,
case when support_segment = 'Enterprise Support' then 10
when support_segment = 'Merchant Support' then 5
when support_segment = 'Business Support' then 1
when support_segment = 'ROW' then 0
end segment_weight,
row_number() over (partition by customer_id order by segment_weight desc, am_name asc) as rn
