SQLエラーメッセージ8120修正

Question

ここで私のエラーがどこにあるのかわかりません。

Column 'Shipments.ShipmentOrderDate' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

Answer 1

あなたはのでGROUP BYを必要とする：これは質問です：

Write a SELECT statement that returns the following columns 
a. ShipmentOrderDate 
b. Clients Email Address 
c. Column that calculates the Total Order called OrderTotal 
d. A Column that uses the Rank() function to return a column named OrderTotalRank that 
ranks the Order Total in Desc Order. 
e. A column that uses the DenseRank() function to return a column called DenseRank that 
ranks the Order Total in Desc Order. 

そして、これは私がコード化されたものです：私は、コードを実行すると

SELECT ShipmentOrderDate, EmailAddress, 
    SUM(sh.ShipItemPrice * sh.Quantity) AS OrderTotalRank, 
    RANK() OVER (ORDER BY SUM(sh.ShipItemPrice * sh.Quantity) DESC) AS OrderTotalRank, 
    DENSE_RANK() OVER (ORDER BY SUM(sh.ShipItemPrice * sh.Quantity) DESC) AS DenseRank 
FROM Clients AS c JOIN Shipments AS s 
    ON c.ClientID = s.ClientID 
    JOIN ShipItems AS sh 
    ON s.ShipmentID = sh.ShipmentID 

が、私はこのエラーを取得しますSELECTに集約関数があります。これらは、使用しているウィンドウ関数とは別のものです。

SELECT ShipmentOrderDate, EmailAddress, 
     SUM(sh.ShipItemPrice * sh.Quantity) AS OrderTotalRank, 
     RANK() OVER (ORDER BY SUM(sh.ShipItemPrice * sh.Quantity) DESC) AS OrderTotalRank, 
     DENSE_RANK() OVER (ORDER BY SUM(sh.ShipItemPrice * sh.Quantity) DESC) AS DenseRank 
FROM Clients c JOIN 
    Shipments s 
    ON c.ClientID = s.ClientID JOIN 
    ShipItems sh 
    ON s.ShipmentID = sh.ShipmentID 
GROUP BY ShipmentOrderDate, EmailAddress;
