连接多个查询的输出

Question

我一直在尝试加入两个具有公共字段的查询的输出，我已经查看了人们之前在类似问题和答案中提供的几个示例，但似乎无法让它们工作我.

我有两个查询，基本上提供 Account_ID、Specific_Transaction_Type_Amount、Transaction_Date 作为第一个查询的输出，然后是第二个查询输出 Account_ID, Account_Value.

第二个查询有点复杂，因为它必须查找帐户项目 ID、该项目的最新价格日期、该价格日期的价格，然后将该项目的数量相加，乘以按帐户 ID 分组的商品价格。

所以第一个查询看起来有点像这样：

Select distinct
ACCOUNT_NUMBER
,TrANSACTION_AMOUNT
,TRANSACTION_DATE
from CLIENT CL
left join
CLIENT_ACCOUNT_LINK CAL on CL.CLIENT_ID = CAL.CAL_CLIENT_ID
left join
ACCOUNT A on CAL.CAL_ACCOUNT_ID = A.ACCOUNT_ID
left join
ACCOUNT_TYPE AT on A.ACCOUNT_TYPE_ID = AT.ACCOUNT_TYPE_ID
left join
ACCOUNT_TRANSACTION ATR on A.ACCOUNT_ID = ATR.ACCOUNT_ID
WHERE 
AT.ACCOUNT_TYPE = 'ACCOUNTYPE2'
AND ATR.TRANSACTION_TYPE = 'TRANSACTIONTYPE6'

第二个查询看起来像这样：

select distinct
A.ACCOUNT_NUMBER
,SUM(AB.ITEM_QTY * PR.ITEM_PRICE) OVER (PARTITION BY A.ACCOUNT_ID) as                     TotalValue
from ACCOUNT A 
join ACCOUNT_BALANCE AB on A.ACCOUNT_ID = AB.ACCOUNT_ID
join ITEM_LIST IL on AB.ITEM_ID = IL.ITEM_ID
join PRICE_DATE PD on IL.ITEM_ID= PD.ITEM_ID
join CODE_LOOKUP cODE on PD.PRICE_STATUS_CODE = CODE.CODE_ID AND CODE.DESCRIPTION = 'ACTIVE'
AND PD.PRICE_DATE = (SELECT MAX(PD2.PRICE_DATE)
FROM PRICE_DATE PD2
WHERE PD2.ITEM_ID = PD.ITEM_ID
AND PD2.PRICE_STATUS_CODE = CODE.CODE_ID
AND sprcp.prcp_effective_date < sysdate + 1)
join PRICE PR on PD.PRICE_ID = PRICE_PRICE_DATE_ID
join PRICE_TYPE PT on PR.PRICE_TYPE_ID = PT.PRICE_TYPE_ID

所以我得到两个结果：

ACCOUNT_ID    TRANSACTION_AMOUNT    TRANSACTION_DATE
_____________________________________________________
123456789      500.23                 07/02/2019

ACCOUNT_ID    TOTAL_VALUE
____________________________
123456789      24365.48

我希望查询 2 中的 TOTAL_VALUE 列出现在查询 1 中。如果我将两个查询合并为一个，查询运行s 很长一段时间才能得到一个内存不足错误。如果我运行他们分开，他们每个人都需要几分钟，但我得到的结果没有任何问题。

我确实尝试根据前面的例子做了类似的事情：

SELECT *
FROM (QUERY1) AS Q1
LEFT JOIN (QUERY2) AS Q2
on Q1.A.ACCOUNT_ID = Q2.A.ACCOUNT_ID

当我尝试运行这个查询时出现语法错误，它似乎特别不喜欢查询别名？

Answer 1

尝试

with 
q2 (select distinct
            A.ACCOUNT_NUMBER
            ,SUM(AB.ITEM_QTY * PR.ITEM_PRICE) OVER (PARTITION BY A.ACCOUNT_ID) as                     TotalValue
            from ACCOUNT A 
            join ACCOUNT_BALANCE AB on A.ACCOUNT_ID = AB.ACCOUNT_ID
            join ITEM_LIST IL on AB.ITEM_ID = IL.ITEM_ID
            join PRICE_DATE PD on IL.ITEM_ID= PD.ITEM_ID
            join CODE_LOOKUP cODE on PD.PRICE_STATUS_CODE = CODE.CODE_ID AND CODE.DESCRIPTION = 'ACTIVE'
            AND PD.PRICE_DATE = (SELECT MAX(PD2.PRICE_DATE)
            FROM PRICE_DATE PD2
            WHERE PD2.ITEM_ID = PD.ITEM_ID
            AND PD2.PRICE_STATUS_CODE = CODE.CODE_ID
            AND sprcp.prcp_effective_date < sysdate + 1)
            join PRICE PR on PD.PRICE_ID = PRICE_PRICE_DATE_ID
            join PRICE_TYPE PT on PR.PRICE_TYPE_ID = PT.PRICE_TYPE_ID),
    q1 as (Select distinct
                ACCOUNT_NUMBER
                ,TrANSACTION_AMOUNT
                ,TRANSACTION_DATE
                from CLIENT CL
                left join
                CLIENT_ACCOUNT_LINK CAL on CL.CLIENT_ID = CAL.CAL_CLIENT_ID
                left join
                ACCOUNT A on CAL.CAL_ACCOUNT_ID = A.ACCOUNT_ID
                left join
                ACCOUNT_TYPE AT on A.ACCOUNT_TYPE_ID = AT.ACCOUNT_TYPE_ID
                left join
                ACCOUNT_TRANSACTION ATR on A.ACCOUNT_ID = ATR.ACCOUNT_ID
                WHERE 
                AT.ACCOUNT_TYPE = 'ACCOUNTYPE2'
                AND ATR.TRANSACTION_TYPE = 'TRANSACTIONTYPE6')
        select * from q1
          join q2  on q1.account_number = q2.account_number
