我正在尝试在ORACLE上插入两个表(示例数据)中的MINUS值。我可以插入所有行,但我无法使用其他表中缺少的行:
示例数据:
SALES TABLE SALES2 TABLE S_DETAILS TABLE
=================== =================== ==================
ID_SALE|DATE_SALE ID_SALE|DATE_SALE ID_SALE|SALE_DETAILS
100 |12/12/2010 100 |12/12/2010 100 |SHIPPED
101 |5/10/2011 101 |5/10/2011 101 |WAITING
102 |10/9/2012 102 |SHIPPED
103 |5/10/2011 103 |PROCESSING
我的代码:
INSERT INTO SALES_RESUME(ID_SALE,DATE_SALE,TOTAL_SALE,SALE_DETAILS)
SELECT A.ID_SALE,A.DATE_SALE,B.TOTAL_SALE,B.SALE_DETAILS
FROM SALES A
JOIN S_DETAILS B ON A.ID_SALE = B.ID_SALE
WHERE A.ID_SALE IN (SELECT ID_SALE FROM SALES
MINUS
SELECT ID_SALE FROM SALES2);
当ID_SALE位于生成的MINUS子查询中时,我想在SALES_RESUME中插入行,插入:
SALES_RESUME
==============================
ID_SALE|DATE_SALE|SALE_DETAILS
102 |10/9/2012|SHIPPED
103 |5/10/2011|PROCESSING

您的查询似乎可以执行您想要的操作。但为什么不写这个?
WHERE A.ID_SALE NOT IN (SELECT ID_SALE FROM SALES2 WHERE ID_SALE IS NOT NULL); -- assuming SALES2.ID_SALE is never NULL
您已经知道ID_SALE
位于第一个表格中。

如果我得到它,我认为这个查询将起作用
SELECT A.ID_SALE,A.DATE_SALE,B.TOTAL_SALE,B.SALE_DETAILS
FROM ((select id_sale,DATE_SALE from SALES) minus (select id_sale,DATE_SALE from SALES2)) A
JOIN S_DETAILS B on A.id = B.id
