蜂巢 TPCDS 查询 30 "Only SubQuery expressions that are top level conjuncts are allowed "

Question

我在尝试 运行 Hive 中的 tpcds 查询 30 时收到上述错误。我做了研究，知道这在 Hive 中是不允许的，所以我想知道如何重写这个查询。我直接从这个网站上得到的。 http://www.tpc.org/tpcds/default5.asp

Error: Error while compiling statement: FAILED: SemanticException Line 0:-1 Unsupported SubQuery Expression 'ctr_state': Only SubQuery expressions that are top level conjuncts are allowed

查询 30

with customer_total_return as
 (select wr_returning_customer_sk as ctr_customer_sk
        ,ca_state as ctr_state, 
   sum(wr_return_amt) as ctr_total_return
 from web_returns
     ,date_dim
     ,customer_address
 where wr_returned_date_sk = d_date_sk 
   and d_year =2000
   and wr_returning_addr_sk = ca_address_sk 
 group by wr_returning_customer_sk
         ,ca_state)
  select  c_customer_id,c_salutation,c_first_name,c_last_name,c_preferred_cust_flag
       ,c_birth_day,c_birth_month,c_birth_year,c_birth_country,c_login,c_email_address
       ,c_last_review_date_sk,ctr_total_return
 from customer_total_return ctr1
     ,customer_address
     ,customer
 where ctr1.ctr_total_return > (select avg(ctr_total_return)*1.2
        from customer_total_return ctr2 
                      where ctr1.ctr_state = ctr2.ctr_state)
       and ca_address_sk = c_current_addr_sk
       and ca_state = 'GA'
       and ctr1.ctr_customer_sk = c_customer_sk
 order by c_customer_id,c_salutation,c_first_name,c_last_name,c_preferred_cust_flag
                  ,c_birth_day,c_birth_month,c_birth_year,c_birth_country,c_login,c_email_address
                  ,c_last_review_date_sk,ctr_total_return
limit 100;

更新

当您使用 tpcds 套件生成查询时，查询 30 可能有拼写错误。这个在客户tablec_last_review_date_sk中不存在需要改成c_last_review_date

使用解析函数在子查询 customer_total_return 中计算 avg(ctr_total_return)，并从 WHERE:

中删除子查询

with customer_total_return as
(
select ctr_customer_sk, ctr_state, ctr_total_return,
       avg(ctr_total_return) over(partition by ctr_state ) as ctr_state_avg
from
 (select wr_returning_customer_sk as ctr_customer_sk
        ,ca_state as ctr_state, 
   sum(wr_return_amt) as ctr_total_return
 from web_returns
     ,date_dim
     ,customer_address
 where wr_returned_date_sk = d_date_sk 
   and d_year =2000
   and wr_returning_addr_sk = ca_address_sk 
 group by wr_returning_customer_sk
         ,ca_state
) s
)

  select  c_customer_id,c_salutation,c_first_name,c_last_name,c_preferred_cust_flag
       ,c_birth_day,c_birth_month,c_birth_year,c_birth_country,c_login,c_email_address
