sql - SSIS 包将数据从 CSV 文件插入临时表，然后从临时表移动到带有站点列的主表

Question

我有一个 CSV 文件，它成功地从源文件移动到序列容器中的数据流任务中的临时表。会有一些这样的序列。然后，我需要将此数据从临时表移动到包含额外列（站点）的主表。我正在使用 SQL 任务从暂存转移到主表。当我运行它时，它会进入我的临时表，但永远不会碰到我的主表。

这是我的执行 SQL 任务中的代码

USE ENSTRDW
UPDATE
    AxonOrders

SET
 AxonOrders.OrderNbr = AxonOrdersExtractCleanCreated.OrderNbr
       ,AxonOrders.OrderStatus = AxonOrdersExtractCleanCreated.OrderStatus
      ,AxonOrders.OrderEndDate = AxonOrdersExtractCleanCreated.OrderEndDate
      ,AxonOrders.InvoiceDate = AxonOrdersExtractCleanCreated.InvoiceDate
      ,AxonOrders.OrderDate = AxonOrdersExtractCleanCreated.OrderDate
      ,AxonOrders.RevenuePerMile = AxonOrdersExtractCleanCreated.RevenuePerMile
      ,AxonOrders.ReadyToInvoice = AxonOrdersExtractCleanCreated.ReadyToInvoice
      ,AxonOrders.OrderCommodity = AxonOrdersExtractCleanCreated.OrderCommodity
      ,AxonOrders.OrderTractors = AxonOrdersExtractCleanCreated.OrderTractors
      ,AxonOrders.BillableMileage = AxonOrdersExtractCleanCreated.BillableMileage
      ,AxonOrders.Site = 'GT'
      ,AxonOrders.LastModified = AxonOrdersExtractCleanCreated.LastModified
      ,AxonOrders.VoidedOn = AxonOrdersExtractCleanCreated.VoidedOn
      ,AxonOrders.OrderDateTimeEntered = AxonOrdersExtractCleanCreated.OrderDateTimeEntered
  
FROM
    AxonOrdersExtractCleanCreated

为什么要使用 UPDATE 命令来插入数据？！

您应该使用 INSERT INTO 命令而不是 UPDATE：

USE ENSTRDW;
INSERT INTO [AxonOrders](OrderNbr,OrderStatus,OrderEndDate,InvoiceDate,OrderDate,RevenuePerMile,ReadyToInvoice,
             OrderCommodity,OrderTractors,BillableMileage,Site,LastModified,VoidedOn,OrderDateTimeEntered)
SELECT           
            OrderNbr,OrderStatus,OrderEndDate,InvoiceDate,OrderDate,RevenuePerMile,ReadyToInvoice,
             OrderCommodity,OrderTractors,BillableMileage,'GT',LastModified,VoidedOn,OrderDateTimeEntered
  
FROM
    AxonOrdersExtractCleanCreated
