SQL子查詢中的條件

Question

我做了這個查詢，現在我必須找到不同的方法，它會返回相同的結果。

SELECT CompanyName, COUNT(Orders.OrderID) Orders 
FROM Customers LEFT OUTER JOIN Orders ON Customers.CustomerID = Orders.CustomerID 
WHERE Country LIKE 'Germany' OR Country LIKE 'Brazil' 
GROUP BY CompanyName HAVING COUNT(Orders.OrderID) >= 10 
ORDER BY Orders ASC; 

所以我做了這個，但我不知道應該在哪裏放置「> = 10」條件。有人能告訴我該怎麼做嗎？我嘗試了一些方法，但沒有奏效。

SELECT CompanyName, (SELECT COUNT(OrderID) FROM Orders WHERE Customers.CustomerID = Orders.CustomerID) AS Orders 
FROM Customers 
WHERE Country LIKE 'Germany' OR Country LIKE 'Brazil' 
ORDER BY Orders ASC; 

這是MS SQL Server的...

Answer 1

SELECT CompanyName, COUNT(Orders.OrderID) Orders 
    FROM Customers JOIN Orders ON Customers.CustomerID = Orders.CustomerID 
    WHERE Country IN('Germany','Brazil') 
    GROUP BY CompanyName 
    HAVING COUNT(Orders.OrderID) >= 10 
    ORDER BY Orders ASC; 

Answer 2

SELECT 
     COMPANYNAME, 
     (SELECT 
      COUNT (ORDERID) 
     FROM 
      ORDERS 
     WHERE 
      CUSTOMERS.CUSTOMERID = ORDERS.CUSTOMERID 
     HAVING 
      COUNT (ORDERID) >= 10) 
      AS ORDERS 
FROM 
     CUSTOMERS 
WHERE 
     COUNTRY LIKE 'Germany' 
     OR COUNTRY LIKE 'Brazil' 
ORDER BY 
     ORDERS ASC;
