SQL交叉联接错误无法绑定多部分标识符

我试图返回表Jobs中的几行，但也返回表JobProducts中的下一个到期日（其中每个JobProduct都有一个到期日）

到目前为止，我有以下几点

SELECT  J.CustomerID,  J.JobID, J.Status, 
J.Deleted, J.JobNo, Customers.CompanyName AS [Company], 
J.DateCreated AS [Date Created], derivedtbl_1.DueDate AS [Due Date] 
FROM Jobs  J
LEFT OUTER JOIN 
Customers ON J.CustomerID = Customers.CustomerID CROSS JOIN 
(SELECT   TOP (1) DueDate, JobProductID, JobID, ProductID, DepartmentID 
FROM      JobProducts AS JobProducts_1 
WHERE    JobProducts_1.JobID = J.JobID 
ORDER BY DueDate) 
AS derivedtbl_1 

但是我得到了错误 无法绑定多部分标识符“J.JobID”

任何帮助都将不胜感激

错误似乎来自SQL Server。我认为您混淆了

交叉连接

（它是笛卡尔积）和

交叉应用

：

SELECT  J.CustomerID,  
        J.JobID, 
        J.Status, 
        J.Deleted, 
        J.JobNo, 
        Customers.CompanyName AS [Company], 
        J.DateCreated AS [Date Created], 
        derivedtbl_1.DueDate AS [Due Date] 
FROM Jobs  J
LEFT JOIN Customers 
    ON J.CustomerID = Customers.CustomerID 
CROSS APPLY (SELECT TOP (1) DueDate, 
                           JobProductID, 
                           JobID, 
                           ProductID, 
                           DepartmentID 
            FROM JobProducts AS JobProducts_1 
            WHERE JobProducts_1.JobID = J.JobID 
            ORDER BY DueDate) 
AS derivedtbl_1

您可以尝试将交叉连接更改为交叉应用

CROSS APPLY
(SELECT   TOP (1) DueDate, JobProductID, JobID, ProductID, DepartmentID 
FROM      JobProducts AS JobProducts_1 
WHERE    JobProducts_1.JobID = J.JobID 
ORDER BY DueDate)
