Question

我有两个表：A和B在两个表上都有相同的列：

Customer_Part_Number,
Lear_Part_Number,
Shipping_ID,
Customer_Name,
Effective_Date,
End_Date,Change_ID,
PO_Number,
PO_Price

我已成功将所有数据从表A复制到表B. 但我的情况是列的记录：

TENANT_ID,          
CUSTOMER_PART_NUMBER,       
SHIPPING_ID,       
EFFECTIVE_DATE

表中的

是相同的，我不希望它将它插入到表B中。我尝试过使用查询：

INSERT INTO OSUSR_1SV_QAD_PO_DATA 
    (TENANT_ID,
     CUSTOMER_PART_NUMBER,
     LEAR_PART_NUMBER,
     SHIPPING_ID,
     CUSTOMER_NAME,
     PROGRAM_NAME,
     EFFECTIVE_DATE,
     END_DATE,
     CHANGE_ID,
     PO_NUMBER,
     PO_PRICE)
SELECT 
     TENANT_ID,
     CUSTOMER_PART_NUMBER,
     LEAR_PART_NUMBER,
     SHIPPING_ID,
     CUSTOMER_NAME,
     PROGRAM_NAME,
     EFFECTIVE_DATE,
     END_DATE,
     CHANGE_ID,
     PO_NUMBER,
     PO_PRICE 
FROM 
OSUSR_1SV_STAGING_FTP A
WHERE 
not exists
 ( SELECT TENANT_ID,
     CUSTOMER_PART_NUMBER,
     LEAR_PART_NUMBER,
     SHIPPING_ID,
     CUSTOMER_NAME,
     PROGRAM_NAME,
     EFFECTIVE_DATE,
     END_DATE,
     CHANGE_ID,
     PO_NUMBER,
     PO_PRICE
     FROM OSUSR_1SV_QAD_PO_DATA B
     WHERE
      A.TENANT_ID = B.TENANT_ID
       and A.CUSTOMER_PART_NUMBER = A.CUSTOMER_PART_NUMBER
       and A.SHIPPING_ID = B.SHIPPING_ID
       and  A.EFFECTIVE_DATE = B.EFFECTIVE_DATE )

此处，如果列TENANT_ID，CUSTOMER_PART_NUMBER，SHIPPING_ID，EFFECTIVE_DATE的记录相同，则不会插入重复记录。

请帮助我。

在第一张图片中，OSUSR_1SV_STAGING_FTP表上有重复数据的基础 TENANT_ID，
CUSTOMER_PART_NUMBER，
SHIPPING_ID，
EFFECTIVE_DATE

但是我需要在表OSUSR_1SV_QAD_PO_DATA上插入像Image 2这样的数据而不重复 TENANT_ID，
CUSTOMER_PART_NUMBER，
SHIPPING_ID，
EFFECTIVE_DATE

我试过这个查询
MERGE OSUSR_1SV_QAD_PO_DATA A
使用OSUSR_1SV_STAGING_FTP B
ON（B.TENANT_ID = A.TENANT_ID和B.CUSTOMER_PART_NUMBER = A.CUSTOMER_PART_NUMBER
和B.SHIPPING_ID = A.SHIPPING_ID和B.EFFECTIVE_DATE = A.EFFECTIVE_DATE）
什么时候匹配呢 DELETE WHERE ID NOT IN（选择MIN（ID）_
来自OSUSR_1SV_STAGING_FTP
GROUP BY CUSTOMER_PART_NUMBER，SHIPPING_ID）
当没有匹配时 INSERT（TENANT_ID，CUSTOMER_PART_NUMBER，LEAR_PART_NUMBER，SHIPPING_ID，CUSTOMER_NAME，PROGRAM_NAME，EFFECTIVE_DATE，END_DATE，CHANGE_ID，PO_NUMBER，PO_PRICE）
VALUES（B.TENANT_ID，B.CUSTOMER_PART_NUMBER，B.LEAR_PART_NUMBER，B.SHIPPING_ID，
B.CUSTOMER_NAME，B.PROGRAM_NAME，B.EFFECTIVE_DATE，B.END_DATE，B.CHANGE_ID，B.PO_NUMBER，B.PO_PRICE）;

Answer 1

替换此部分

not exists
( SELECT 1
 FROM OSUSR_1SV_QAD_PO_DATA B
 WHERE
  A.TENANT_ID = B.TENANT_ID
   --and A.CUSTOMER_PART_NUMBER = A.CUSTOMER_PART_NUMBER --you are Comparing same value here
   and A.CUSTOMER_PART_NUMBER = B.CUSTOMER_PART_NUMBER  
   and A.SHIPPING_ID = B.SHIPPING_ID
   and  CAST(A.EFFECTIVE_DATE AS DATE) = CAST(B.EFFECTIVE_DATE AS DATE) )

Answer 2

尝试此查询：

        INSERT INTO OSUSR_1SV_QAD_PO_DATA 
(TENANT_ID,
 CUSTOMER_PART_NUMBER,
 LEAR_PART_NUMBER,
 SHIPPING_ID,
 CUSTOMER_NAME,
 PROGRAM_NAME,
 EFFECTIVE_DATE,
 END_DATE,
 CHANGE_ID,
 PO_NUMBER,
 PO_PRICE)

Select TENANT_ID,
 CUSTOMER_PART_NUMBER,
 LEAR_PART_NUMBER,
 SHIPPING_ID,
 CUSTOMER_NAME,
 PROGRAM_NAME,
 EFFECTIVE_DATE,
 END_DATE,
 CHANGE_ID,
 PO_NUMBER,
 PO_PRICE 
 from OSUSR_1SV_STAGING_FTP A

 INNER JOIN (select TENANT_ID,CUSTOMER_PART_NUMBER,SHIPPING_ID,EFFECTIVE_DATE from OSUSR_1SV_STAGING_FTP 
    group by TENANT_ID,CUSTOMER_PART_NUMBER,SHIPPING_ID,EFFECTIVE_DATE) as NoDuplicate ON A.TENANT_ID=NoDuplicate.TENANT_ID

在SQL Server 2008中将非重复数据从父表插入子表
