获取第二个最新日期的价格的Sql查询

我有一个疑问：

select @cost = @cost +                  
    (select top 1 price from
    (select top 2 price, date  from myTable order by date DESC)
     order by date ASC
)

我得到一个错误：关键字“order”附近的语法不正确。 如何修复此问题？

我猜此子查询

(select top 2 price, date  from myTable order by date DESC)

需要一个别名，像这样

(select top 2 price, date  from myTable order by date DESC) sq

但我会这样写：

SELECT @cost = @cost + (
SELECT price FROM (
SELECT price, date, ROW_NUMBER() OVER (ORDER BY date DESC) AS rownum
) sq WHERE rownum = 2
)

我猜这个子查询

(select top 2 price, date  from myTable order by date DESC)

需要一个别名，像这样

(select top 2 price, date  from myTable order by date DESC) sq

但我会这样写：

SELECT @cost = @cost + (
SELECT price FROM (
SELECT price, date, ROW_NUMBER() OVER (ORDER BY date DESC) AS rownum
) sq WHERE rownum = 2
)
