 INSERT INTO  OrderArchive                               

    (OrderNumber,OrderDate,StockItem,Quantity,UnitPrice,SalesRep,Customer,ArchiveDate)     
    SELECT "ORDER".OrderNo,
    "ORDER".OrderDate,
    Stock.StockNo||' '||Stock.StockDesc,
    Orderline.Quantity,
    Orderline.UnitPrice,
    Person.FirstName||' '||Person.Surname,
    Person.FirstName||' '||Person.Surname,
    OrderArchive.ArchiveDate
    FROM "ORDER"
    INNER JOIN Stock
        ON Stock.StockNo||' '||Stock.StockDesc = OrderAchive.StockItem
    INNER JOIN Orderline
        ON Orderline.Quantity = OrderArchive.Quantity
    INNER JOIN Orderline
        ON Orderline.UnitPrice = OrderArchive.UnitPrice
    INNER JOIN Person
        ON Person.FirstName||' '||Person.Surname = OrderArchive.SalesRep
    INNER JOIN Person       
        ON Person.FirstName||' '||Person.Surname = OrderArchive.Customer 
    WHERE "ORDER".OrderDate  < DATEADD('M',6,SYSDATE);

我试图先解决它，但是无法管理它....我正在尝试将超过6个月的订单移至OrderArchive ... OrderArchive有OrderNo＆amp;订单日期来自＆＃34; ORDER＆＃34;表库存项目是StockID和Stockdesc的组合，来自库存表数量和单位成本来自订单表salesrep，客户来自人员表，而datearchived是日期的sysdate订单已存档

Answer 1

为此，您需要一种方法将Person记录加入TableOrder记录。此代码假定您在PersonID表上有TableOrder。您可以在CustomerID表格中使用SalesPersonID或TableOrder或类似内容将其加入Person表格，但我不清楚。

INSERT INTO ArchiveTable (col_1,col_2,col_3,col_4 etc)
    SELECT
        o.OrderNo,
        o.OrderDate,
        p.StockNo||' '||p.StockDesc,
        p.FirstName||' '|| p.Surname
    FROM TableOrder o
        INNER JOIN Person p
            ON p.PersonID = o.PersonID
    WHERE o.orderdate < DATEADD('M',12,SYSDATE)

Answer 2

我认为您没有从查询中获得预期的输出，因为您同时加入Person表同时包含SalesRep和Customer名称。因此，只有订单具有SalesRep和Customer的相同名称时，您才能获得任何数据。因此，我为Person表创建了不同的表别名，如下所示：

INSERT INTO  OrderArchive
    (OrderNumber,OrderDate,StockItem,Quantity,UnitPrice,SalesRep,Customer,ArchiveDate)     
SELECT 
    "ORDER".OrderNo,
    "ORDER".OrderDate,
    Stock.StockNo||' '||Stock.StockDesc,
    Orderline.Quantity,
    Orderline.UnitPrice,
    Person_SR.FirstName||' '||Person_SR.Surname,
    Person_C.FirstName||' '||Person_C.Surname,
    OrderArchive.ArchiveDate
FROM "ORDER"
INNER JOIN Stock
ON Stock.StockNo||' '||Stock.StockDesc = OrderAchive.StockItem
INNER JOIN Orderline
ON Orderline.Quantity = OrderArchive.Quantity
INNER JOIN Orderline
ON Orderline.UnitPrice = OrderArchive.UnitPrice
INNER JOIN Person Person_SR
ON Person_SR.FirstName||' '||Person_SR.Surname = OrderArchive.SalesRep
INNER JOIN Person Person_C       
ON Person_C.FirstName||' '||Person_C.Surname = OrderArchive.Customer 
WHERE "ORDER".OrderDate  < DATEADD('M',6,SYSDATE);

Answer 3

INSERT INTO OrderArchive（OrderNumber，OrderDate，StockItem，Quantity，UnitPrice，SalesRep，Customer）选择“订购”。订单没有， “ORDER” .OrderDate， Stock.StockNo ||' “|| Stock.StockDesc， Orderline.Quantity， Stock.UnitCost， “ORDER” .SalesRepID， Person.FirstName ||” “|| Person.Surname 来自内部联系人（“订购”左边加入（订单内联股票在Orderline.StockID = Stock.StockNo） ON “ORDER” .OrderNo = OrderLine.OrderNo） ON Person.PersonID =“ORDER”.CustomerID 在哪里“订购”。订单日期＆lt; ADD_MONTHS（SYSDATE，-6）订购“订购”。订单编号;

SELECT * FROM OrderArchive;

几乎完成我只需要让SalesRepID说出salesrep的姓氏，但大部分已经完成：）
