有关SQL Server查询

Question

这是我的查询在SQL：

with cte 
as(
    select top 1 
    Id, 
    (((DATEPART(hour, CAST([Time] AS DATETIME)) * 60) + (DATEPART(minute, CAST([Time] AS DATETIME))))) AS Tim, 
    Price 
from Prices order by [Time] desc 
) 
,cte1 as(
    select 
    (((DATEPART(hour, CAST([Time] AS DATETIME)) * 60) + (DATEPART(minute, CAST([Time] AS DATETIME))))) as tim1 
    from M1 
) 

，现在我想做到这一点;如果cte.tim = cte1.tim1，更新表中的一行否则插入表中，但我不知该如何？ 非常感谢

您只能使SELECT或UPDATE，而不是两个同时！
