Question

所以我有一种情况，我知道该过程将查询以UTCStampTime方式格式化的行。我遇到的问题是当我想在两个CTE上建立一个查询时，我只需要在每个CTE变量的时间相等时返回。但问题是我的查询仅查看最后10分钟，并且我只希望当utcTimeStamp列的分钟相同时两行相等。这是我正在运行的查询。

   GO
    declare @fqnLine1Downtime varChar(4000)
   declare @fqnLine1Throughput varChar(400) 
    declare @fqnLine2Downtime varChar(4000)
    declare @fqnLine2Throughput varChar(400) 
    declare @parameter1Line1 varChar(4000) 
   declare @parameter2Line1 varChar(4000)
   declare @parameter1Line2 varChar(4000) 
   declare @parameter2Line2 varChar(4000)  
    declare @server varChar(200)
   declare @timeStart datetime
   declare @timeEnd datetime


   WITH 
CTEThroughputLine1(Time, Amount, ThroughputLine1)
  AS
 --Define the query
(   
    SELECT CONVERT(VarChar(20),utcTimeStamp) as Time, shortName as 

      ThroughputLine1, valueAsInt as Amount 
        From dbo.History(@fqnLine1Throughput, @parameter2Line1, @timeStart, 
    @timeEnd, @server)
     ),

   CTEThroughputLine2(ThroughputLine2, Amount, Time)
   AS
   (
    Select shortName as ThroughputLine2, valueAsFloat as Amount,
     CONVERT(VarChar(20),utcTimeStamp) as Time
    From dbo.History(@fqnLine2Throughput, @parameter2Line2, @timeStart, 
     @timeEnd, @server)
     )

   select * from CTEThroughputLine1 as Line1 inner join 
  CTEThroughputLine2 as Line2 on Line1.Time = Line2.Time

我故意不包含变量的设置，因为它包含我公司的私人信息。我认为这应该足以解决这个问题。请帮忙或指出提示。
