内部选择语句未注册为单组函数...“不是单组组函数”

【中文标题】内部选择语句未注册为单组函数...“不是单组组函数”

【英文标题】：inner select statement not registering as a single-group function... "not a single-group group function"

【问题描述】：

由于我使用的报告软件，我必须将所有内容都放在一个 sql 语句中以生成报告。但是，Oracle SQL 似乎并没有让我创建一个带有单组结果的内部选择，即使它在最终产品中只有一个结果。 （所有其他结果都是单组函数）。 这是我的 SQL：

select   
COUNT(*) as TOTAL_RXS, 
SUM(rx_tx.brand_acquisition_cost) as TOTAL_COST,
SUM(case rx_tx.drug_dispensed 
    when 'B' then (rx_tx.brand_price - rx_tx.brand_discount)
when 'G' then (rx_tx.generic_price - rx_tx.generic_discount)
end) 
    as TOTAL_PRICE,
 SUM(case rx_tx.drug_dispensed
    when 'B' then (rx_tx.brand_price - rx_tx.brand_discount - rx_tx.brand_acquisition_cost)
when 'G' then (rx_tx.generic_price - rx_tx.generic_discount - rx_tx.brand_acquisition_cost)
end)
as TOTAL_PROFIT

    , (select 
   SUM(tx_tp.balance_due_from_tp)
       from eps2.tx_tp 
   join eps2.rx_tx on rx_tx.id = tx_tp.rx_tx_id
       where 1=1
-- This results in CLAIM STATUS being 'F'
    AND rx_tx.fill_date is not NULL 
    AND rx_tx.returned_date is not NULL 
    AND rx_tx.reportable_sales_date is NULL
    AND (tx_tp.paid_status like '%PAID%' 
    OR tx_tp.paid_status like '%PART%') ) as TOTAL_RECEIVABLES

from eps2.vw_rx_summary join eps2.rx_tx
     on vw_rx_summary.last_filled_rx_tx_id = rx_tx.id
-- where TRUNC(rx_tx.fill_date,'DD') = TRUNC(SYSDATE - 1,'DD')

谁能帮帮我？ 提前致谢。

【问题讨论】：

您的查询缺少外部查询的 from 语句。如果这不是完整的查询，请显示完整的查询。

对不起...我通过不包括查询的某些部分来增加简单性并保护公司 sql 代码资产。但这是完整的查询。谢谢。

我想称之为的这种“屏蔽”或类型转换似乎对我不起作用。它说“异常：java.sql.SQLException：ORA-00936：缺少表达式”

【参考方案1】：

select   COUNT(*) as TOTAL_RXS, 
     SUM(rx_tx.brand_acquisition_cost) as TOTAL_COST,
     MAX(select 
        SUM(tx_tp.balance_due_from_tp) as total_receivables
      from eps2.tx_tp 
        join eps2.rx_tx on rx_tx.id = tx_tp.rx_tx_id
      where 1=1
      AND (tx_tp.paid_status like '%PAID%' 
      OR tx_tp.paid_status like '%PART%') ) as total_receivables

为total_receivables 添加MAX() 以将其屏蔽为聚合 函数！
