如何在 SQL Server 2014 中获取昨天和今天之间的交易？

Question

我正在尝试每小时统计昨天发生的所有交易。我不希望今天进行交易。但我似乎无法在条件下正确获取代码。

到目前为止我的代码：

SELECT  CAST(TransDT as DATE) as 'TransDate' 
       ,CAST(DATEPART(Hour, TransDT) as varchar) + ':00' as 'Hour' 
       ,LaneID
       ,Direction
       ,COUNT(*) as 'Ct'

FROM Traffic_analysis

WHERE TransDT >= DATEADD (DAY, -1 , SYSDATETIME())
  AND TransDT < CAST(DATEPART(DAY, SYSDATETIME()) as int) --This is the faulty line.

GROUP BY CAST(TransDT as DATE), DATEPART(Hour, TransDT), LaneID, Direction
ORDER BY CAST(TransDT as DATE) ASC

如果我注释掉整条故障线，我也会得到昨天和今天的结果。我只需要昨天的结果。

我想要做的是显示一份报告，其中包含一个图表，显示每小时、每条车道、每个方向的交通情况。将所有 NB 流量放在一列中，将所有 SB 流量放在另一列中会更好。也许是 UNION 加入？

Answer 1

如果我理解你的问题，你可以进行以下操作：

Where   TransDT >= Convert(Date, DateAdd(Day, -1, GetDate())
And     TransDT < Convert(Date, GetDate())

Answer 2

你试过吗？

WHERE cast(TransDT as date) > DATEADD (DAY, -2 , cast(SYSDATETIME() as date))
  AND cast(TransDT as date) <= DATEADD (DAY, -1 , cast(SYSDATETIME() as date))

其实我觉得这样就够了

WHERE cast(TransDT as date) = DATEADD (DAY, -1 , cast(SYSDATETIME() as date))

Answer 3

TransDT 是一个日期，但是你比较的是一个 INT。

尝试这样的事情：

TransDT = CAST(SYSDATETIME() AS DATE)
