我试图寻找我的问题的答案，但未能得到真正有帮助的答案。我已经写了一个 sql 代码，但似乎无法找到问题所在。是否可以在“FROM”部分放置子查询？

SELECT S2.ITEM,
       S1.SHOP_ORDER,
       S1.OPERATION_NO,
       S1.START_DATE,
       S1.QTY_GOODS,
       S1.QTY_ENTERED,
       S1.QTY_MRB
FROM   (SELECT SHOP_ORD_RPT.OPERATION_NO,
               SHOP_ORD_RPT.SHOP_ORDER
        FROM   FLAME.SHOP_ORD_RPT
        WHERE  SHOP_ORD_RPT.OPERATION_NO = 110
                OR SHOP_ORD_RPT.OPERATION_NO = 370) AS S1
       JOIN (SELECT SHOP_ORD.SHOP_ORDER
             FROM   FLAME.SHOP_ORD
             WHERE  SHOP_ORD.ITEM = '3A2375'
                     OR SHOP_ORD.ITEM = '3A2703')AS S2
         ON S1.SHOP_ORDER = S2.SHOP_ORDER;

我在运行脚本时收到的错误是：

SQL 命令未正确结束

如果有人可以提供帮助，我将不胜感激。非常感谢 - 露丝

尝试在子查询AS之后删除关键字FROM，JOIN如下所示

SELECT S2.ITEM, S1.SHOP_ORDER, S1.OPERATION_NO, S1.START_DATE,S1.QTY_GOODS, S1.QTY_ENTERED, S1.QTY_MRB
FROM (
    SELECT SHOP_ORD_RPT.OPERATION_NO, SHOP_ORD_RPT.SHOP_ORDER
    FROM FLAME.SHOP_ORD_RPT
    WHERE SHOP_ORD_RPT.OPERATION_NO =110
    OR SHOP_ORD_RPT.OPERATION_NO =370
    )  S1
JOIN (
    SELECT SHOP_ORD.SHOP_ORDER
    FROM FLAME.SHOP_ORD
    WHERE SHOP_ORD.ITEM ='3A2375'
    OR SHOP_ORD.ITEM ='3A2703'
    )  S2
ON S1.SHOP_ORDER = S2.SHOP_ORDER;

可以在 from 子句中放置子查询。尝试这个：

SELECT S2.ITEM,
       S1.SHOP_ORDER,
       S1.OPERATION_NO,
       S1.START_DATE,
       S1.QTY_GOODS,
       S1.QTY_ENTERED,
       S1.QTY_MRB
FROM   (SELECT SHOP_ORD_RPT.OPERATION_NO,
               SHOP_ORD_RPT.SHOP_ORDER
        FROM   FLAME.SHOP_ORD_RPT
        WHERE  SHOP_ORD_RPT.OPERATION_NO = 110
                OR SHOP_ORD_RPT.OPERATION_NO = 370) S1,
      (SELECT SHOP_ORD.SHOP_ORDER
       FROM   FLAME.SHOP_ORD
       WHERE  SHOP_ORD.ITEM = '3A2375'
               OR SHOP_ORD.ITEM = '3A2703') S2
WHERE S1.SHOP_ORDER = S2.SHOP_ORDER;
