使用光标将库存分配给销售订单

Question

我正在使用 MS SQL Server 2014。我正在尝试将库存分配给销售订单。销售订单可以有多行，并且库存代码可以重复。分配的库存对于每个发生都有唯一的参考。 我希望将股票逐行分配给股票代码，一旦分配完成，@allocation 临时表就会更新，因此当光标下一次运行时，它只会选择空闲股票，而分配的股票将被忽略。 我还没有添加这个元素，但是当我尝试按原样运行代码时，我收到以下错误

消息 208，级别 16，状态 1，第 67 行无效的对象名称“ctee”。

任何有关 cte 无效的原因的帮助都会非常感激。

我的代码如下所示。

IF OBJECT_ID('[dbo].[@allocation]') is not null
 DROP TABLE [dbo].[@allocation]
 declare @RESULT AS TABLE(COR_UNIQUE VARCHAR(20),COR_PART_ONLY varchar(16),COR_OUR_NUMBER  varchar(16),COR_QTY_ORDERED   decimal(18,5) );
 declare @allocation AS TABLE(L_U VARCHAR(20),C_U VARCHAR(20),L_PART varchar(16),L_PHY DECIMAL(18,5),R_T DECIMAL(18,5),ORD_RUN DECIMAL(18,5),T_L DECIMAL(18,5),FINAL_T_L DECIMAL(18,5));

当您定义 CTE 时，它仅在批次的生命周期内存在。

在您的代码中，您将 ctee 定义为第 62 行的几个 CTE 中的最后一个，但随后立即在第 65 行执行 insert into - 这是该批次的 end。

以下select * from ctee 是一个新 批次，未定义ctee。
