的Oracle SQL连接两个表/视图避免交叉产品

我有两个表/视图，我想适当加入。它们是V_ARINVOICE_ALL和V_GLBATCH_AR_COGS。下图中的第三张表V_ARINVOICE_ALL仅供参考。的Oracle SQL连接两个表/视图避免交叉产品

目前我得到的行的金额错误被退回，因为，我认为，那种交叉联接。我试图从V_GLBATCH_AR_COGS加入Credit。

我用下面的SQL查询来加入V_ARINVOICE_ALL和V_ARINVOICE_ALL和我得到的一切除了`信用正确的结果没有被选择：

SELECT 
V_ARINVOICE_ALL.INVOICE_DATE, 
V_ARINVOICE_ALL.ARCUSTO_COMPANY, 
V_ARINVOICE_ALL.ARCUSTO_CUSTNO, 
V_ARINVOICE_ALL.INVOICE_NO 


FROM 
IQMS.V_ARINVOICE_ALL V_ARINVOICE_ALL 


INNER JOIN 
IQMS.V_GLACCT V_GLACCT 
ON 
    V_ARINVOICE_ALL.GLACCT_ID_SALES = V_GLACCT.ID AND V_GLACCT.ACCT = '3648-00-0' 



WHERE 
V_ARINVOICE_ALL.ARCUSTO_CUSTNO = 'OX01' 
AND 
V_ARINVOICE_ALL.INVOICE_DATE >= TO_DATE('05/04/2016', 'dd/mm/yyyy') 
AND 
V_ARINVOICE_ALL.INVOICE_DATE <= TO_DATE('15/06/2017', 'dd/mm/yyyy') 

ORDER BY 
V_ARINVOICE_ALL.INVOICE_DATE

结果（41行）

|INVOICE_DATE|...| INVOICE| 
    +------------+---+--------+ 
    | 05/04/2016|...| 494658| 
    | 20/05/2016|...| 495274| 
    | 20/05/2016|...| 495275|

但是，当我尝试加入V_ARINVOICE_ALL和V_GLBATCH_AR_COGS用下面的查询：

SELECT 
V_ARINVOICE_ALL.INVOICE_DATE, 
V_ARINVOICE_ALL.ARCUSTO_COMPANY, 
V_ARINVOICE_ALL.ARCUSTO_CUSTNO, 
V_ARINVOICE_ALL.INVOICE_NO, 
V_GLBATCH_AR_COGS.CREDIT AS "INCOME" 


FROM 
IQMS.V_ARINVOICE_ALL V_ARINVOICE_ALL 


INNER JOIN 
IQMS.V_GLBATCH_AR_COGS V_GLBATCH_AR_COGS 
ON 
V_ARINVOICE_ALL.GLBATCHID_ID = V_GLBATCH_AR_COGS.ID 
AND V_ARINVOICE_ALL.GLPERIODS_ID_AR = V_GLBATCH_AR_COGS.GLPERIODS_ID 
AND V_GLBATCH_AR_COGS.DESCRIP LIKE '%OX01%ITEMS%' AND V_GLBATCH_AR_COGS.ACCT = '3648-00-0' 



WHERE 
V_ARINVOICE_ALL.ARCUSTO_CUSTNO = 'OX01' 
AND 
V_ARINVOICE_ALL.INVOICE_DATE >= TO_DATE('05/04/2016', 'dd/mm/yyyy') 
AND 
V_ARINVOICE_ALL.INVOICE_DATE <= TO_DATE('15/06/2017', 'dd/mm/yyyy') 

ORDER BY 
V_ARINVOICE_ALL.INVOICE_DATE

我得到的是这样的：（165行）

|INVOICE_DATE|...| INVOICE| INCOME| 
    +------------+---+--------+--------+ 
    | ...  |...| ... | ... | 
    | 23/06/2016|...| 495667|  225| 
    | 23/06/2016|...| 495667|  225| 
    | 23/06/2016|...| 495667|  225| 
    | 23/06/2016|...| 495667|  225| 
    | 23/06/2016|...| 495667|  225| 
    | 23/06/2016|...| 495667|  225| 
    | 23/06/2016|...| 495667|  450| 
    | 23/06/2016|...| 495667|  450| 
    | 23/06/2016|...| 495667|  450| 
    | ...  |...| ... | ... |

期望的结果（41行）

|INVOICE_DATE|...| INVOICE| INCOME| 
    +------------+---+--------+--------+ 
    | ...  |...| ... | ... | 
    | 23/06/2016|...| 495667|  225| 
    | 23/06/2016|...| 495667|  225| 
    | 23/06/2016|...| 495667|  450| 
    | ...  |...| ... | ... |

我多一点熟悉加入比我以前。但我不确定我是否做对了。我试过正确的连接，右外连接，左连接，左外连接等。我在这里做错了什么？

编辑2：第一次编辑是坏的没有意义。我不知道这是否帮助，但只有两行，将是

| 23/06/2016|...| 495667|  225| 
    | 23/06/2016|...| 495667|  225|

在表中的WHERE条款上加入匹配，其中：V_ARINVOICE_ALL.GLPERIODS_ID_AR = V_GLBATCH_AR_COGS.GLPERIODS_ID AND V_GLBATCH_AR_COGS.DESCRIP LIKE '%OX01%ITEMS%' AND V_GLBATCH_AR_COGS.ACCT = '3648-00-0

但仍然会得到它的两倍以上。所以我想这与1到Many的关系有关系。我不知道该如何处理。

如果这是任何帮助。

为什么这个标签与Excel，我看不出有什么练成都在这里。 – Luuklag

对不起。这是在excels电源查询中完成的。我会删除它。 – spyr0

看起来像一对多的关系。 COGS表中的值比您需要的更多（可能是其他列填充了其他数据）。

尝试SELECT DISTINCT限制对唯一值选取的资料栏：

SELECT DISTINCT -- DISTINCT goes here 
V_ARINVOICE_ALL.INVOICE_DATE, 
V_ARINVOICE_ALL.ARCUSTO_COMPANY, 
V_ARINVOICE_ALL.ARCUSTO_CUSTNO, 
V_ARINVOICE_ALL.INVOICE_NO, 
V_GLBATCH_AR_COGS.CREDIT AS "INCOME" 


FROM 
IQMS.V_ARINVOICE_ALL V_ARINVOICE_ALL 


INNER JOIN 
IQMS.V_GLBATCH_AR_COGS V_GLBATCH_AR_COGS 
ON 
V_ARINVOICE_ALL.GLBATCHID_ID = V_GLBATCH_AR_COGS.ID 
AND V_ARINVOICE_ALL.GLPERIODS_ID_AR = V_GLBATCH_AR_COGS.GLPERIODS_ID 
AND V_GLBATCH_AR_COGS.DESCRIP LIKE '%OX01%ITEMS%' AND V_GLBATCH_AR_COGS.ACCT = '3648-00-0' 



WHERE 
V_ARINVOICE_ALL.ARCUSTO_CUSTNO = 'OX01' 
AND 
V_ARINVOICE_ALL.INVOICE_DATE >= TO_DATE('05/04/2016', 'dd/mm/yyyy') 
AND 
V_ARINVOICE_ALL.INVOICE_DATE <= TO_DATE('15/06/2017', 'dd/mm/yyyy') 

ORDER BY 
V_ARINVOICE_ALL.INVOICE_DATE
