SQL Server T-SQL CASE错误

Question

我在使用T-SQL（SQL Server 2000）的CASE上收到错误。任何反馈都非常感谢

  

错误是消息156，级别15，状态1，行2语法不正确   关键字'CASE'。

- 查询如下：

select c.name,c.customerid,c.linkid
      ,case when c.linkid=x.linkid then x.orderitem end as orderitem
      ,case when c.linkid=x.linkid then x.orderdate end as orderdate
from customer as c
Inner join 
(
    Select C.CustomerID, C.LinkID, O.OrderItem,O.OrderDate
    From Customer as C
    JOIN Orders as O 
        ON C.CustomerKey=O.OrderKey
    WHERE O.OrderDate='mm-dd-yyyy'
) as X
    on c.customerid=x.customerid
order by c.customerid
        ,case when c.linkid=x.linkid then 0 else 1 end asc
        ,c.linkid
