ORACLE 10G，我是oracle 10g 的新手如何在没有联合的情况下编写查询的语法并并排查看列

如何解决ORACLE 10G，我是oracle 10g 的新手如何在没有联合的情况下编写查询的语法并并排查看列

我想通过贸易代码比较标题和数量。 00PAT 是订单，553028 是发票。 4 件商品订购 3 件商品。

SELECT CUS.CODE,CUS.NAME,F1.ID,F1.FTRDATE,F1.TRADECODE,MAT.SUBCODE1,MAT.DESCRIPTION,S1.PRIMARYQTY
FROM CUSTOMER CUS,FINTRADE F1,STORETRADELINES S1,MATERIAL MAT
WHERE S1.FTRID=F1.ID AND CUS.ID=F1.CUSID AND MAT.ID=S1.ITEID
AND F1.DSRID='14500' AND F1.FTRDATE='13/4/2021'
UNION   
SELECT CUS.CODE,F2.ID,F2.FTRDATE,F2.TRADECODE,S2.PRIMARYQTY
FROM CUSTOMER CUS,FINTRADE F2,STORETRADELINES S2,MATERIAL MAT
WHERE S2.FTRID=F2.ID AND CUS.ID=F2.CUSID AND MAT.ID=S2.ITEID
AND F2.DSRID='15500' AND F2.FTRDATE='14/4/2021'

解决方法

对我来说，它看起来像这样：

SELECT cus.code,cus.name,f1.id,f1.ftrdate,f1.tradecode,mat.subcode1,mat.description,s1.primaryqty
FROM customer         cus
JOIN fintrade         f1  ON f1.cusid = cus.id
JOIN storetradelines  s1  ON s1.ftrid = f1.id
JOIN material         mat ON mat.id = s1.iteid
WHERE f1.dsrid IN ('14500','15500')
  AND f2.ftrdate IN (DATE '2021-04-13',DATE '2021-04-14');
