テーブル Jobs からいくつかの行を返そうとしていますが、テーブル JobProducts (各 JobProduct には期日があります) からの次の期日も返します。

私はこれまでに次のことを持っています

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

しかし、エラー The multi-part identifier "J.JobID" could not be bind. が表示されます。

どんな助けでも大歓迎です

エラーは SQL Server からのもののようです。私はあなたが混同していると思いますCROSS JOIN（これはデカルト積です）CROSS APPLY：

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

クロス結合をクロス適用に変更してみてください

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