Sql 非空值之间的升序和降序

使用此查询：

WITH CTE
AS
(
    SELECT 
        concat(e.FirstName, ' ', e.LastName) as Employee_Name, 
        g.GrantName, 
        g.Amount, 
        case 
            when g.Amount IS NULL THEN 0 
            ELSE 1 
        END AS IS_NULL_Amount
    from Employee e 
        LEFT OUTER join [Grant] g
            ON g.EmpID = e.EmpID
)

SELECT 
    CTE.Employee_Name, 
    CTE.GrantName, 
    CTE.Amount 
from CTE
ORDER BY CTE.IS_NULL_Amount desc

我得到以下结果：

Employee_Name      GrantName                   Amount

如何仅在not NULL值之间对ASC和DESC进行排序？

排序结束为\u NULL\u金额和金额

ORDER BY CTE.IS_NULL_Amount desc,Amount asc

---

请尝试使用以下ORDERBY子句：

order by cte.Is_Null_Amount desc, EmployeeName

或

---

请澄清“仅在非空值之间对ASC和DESC进行排序”的含义。您想按哪一列排序，金额？最后保留空值？

order by cte.Is_Null_Amount desc, Amount desc
