SAP B1查询返回“必须声明标量变量”错误

我正在尝试创建一个下拉菜单，它将限制物品采购员使用以下SQL代码查询结果。但是，我不断收到一个错误，指出我需要声明标量变量@ItemBuyer，尽管它明确声明并在代码中进行了设置。SAP B1查询返回“必须声明标量变量”错误

DECLARE @ItemBuyer VARCHAR(30) 
    SET @ItemBuyer= /* T3.OwnerCode */ '[%1]' 

    DECLARE @SQL VARCHAR(MAX) 
    SET @SQL = 'SELECT T3.[DocNum] AS DocNumber, T3.[CardCode] AS 
    VendorCode, T3.[CardName] AS VendorName, T3.OwnerCode as BuyerID, T2. 
    [ItemCode] AS ItemNo, T2.[U_CPM_LegItemNo] AS LegacyItemNumber, T2. 
    [Dscription] AS ItemDescription, T2.[U_CPM_ConfDate] AS POConfirmDate, 
    T2.[OpenCreQty] AS CreditMemoAmount FROM [dbo].[OITG] T0 , [dbo]. 
    [OITM] T1 INNER JOIN [dbo].[POR1] T2 ON T2.[ItemCode] = T1. 
    [ItemCode] INNER JOIN [dbo].[OPOR] T3 ON T3.[DocEntry] = T2. 
    [DocEntry] WHERE (T2.[OpenCreQty] > (0)) AND (T2.[U_CPM_ConfDate] 
    IS NULL ) and (T3.[OwnerCode] = @ItemBuyer)' 

    EXEC(@SQL)

我也尝试声明和设置变量象下面这样：

DECLARE @ItemBuyer VARCHAR(30) = /* T3.[OwnerCode] */ '[%0]'

但后来我得到一个错误，指出语法是错误的，甚至可以通过变量现在返回正确的值。我有点卡在这里。希望有人能帮助我。

感谢，

为什么使用动态sql？ –

您正在使用动态查询，但您没有为动态查询提供价值。 – Hybridzz

我会改写这样的查询：

/*SELECT FROM [dbo].[OPOR] P1*/ 
declare @ItemBuyer as int 
/* WHERE */ 
set @ItemBuyer = /* P1.OwnerCode */ '[%0]' 


SELECT T3.[DocNum] AS DocNumber 
, T3.[CardCode] AS VendorCode 
, T3.[CardName] AS VendorName 
, T3.OwnerCode as BuyerID 
, T2.[ItemCode] AS ItemNo 
, T2.[U_CPM_LegItemNo] AS LegacyItemNumber 
, T2.[Dscription] AS ItemDescription 
, T2.[U_CPM_ConfDate] AS POConfirmDate 
, T2.[OpenCreQty] AS CreditMemoAmount 
FROM [dbo].[POR1] T2 
INNER JOIN [dbo].[OPOR] T3 ON T3.[DocEntry] = T2.[DocEntry] 
WHERE T2.[OpenCreQty] > 0 
AND T2.[U_CPM_ConfDate] IS NULL 
and T3.[OwnerCode] = @ItemBuyer

我仍然不能设法记住动态语法查询，所以我必须使用此链接每一次我想要做到这一点：http://www.clientsfirst-us.com/blog/sap/sap-business-one/user-defined-prompts-in-sap-business-one-queries/

请注意，我摆脱了几个表，你没有在你的使用或您的where报表。这可能不会使查询速度产生很大的差异，但它只是使它更清晰。（我还清理了格式以将其放入我最喜欢的样式中，但这不是必须的）
