我有下面的查询,我把它放在一起,它运行得很糟糕(因为我相信你可以看到).

我很确定它与我转换日期时间的方式有关,这样我就可以参考昨天的数据了.

dtInteractionLocalStartTime是一个日期时间字段,我希望它显示为mm/dd/yyyy而不是yyyy-mm-dd hh:mm:ss.sss

关于如何优化这个的任何想法？我已经度过了这两天,我无法弄明白.

这是我的查询:

SELECT TOP 100 PERCENT
       Date ,
       CONVERT(varchar, VDN) AS VDN ,
       COUNT(*) AS Calls ,
       Avaya
FROM ( SELECT DISTINCT TOP 100 PERCENT
              CONVERT(varchar,dtInteractionLocalStartTime,101) AS Date ,
              vcVectorNumber AS VDN ,
              iCompoundID ,
              'CM03' AS Avaya
       FROM NICEHUB3ADTM.nice_dw.dbo.vwNiceDBKitInteraction AS i
       WHERE CONVERT(varchar(10) , dtInteractionLocalStartTime,101) = CONVERT(varchar(10),GETDATE()-1,101)
         AND iMediaTypesId = 2
         AND tiCallDirectionTypeID = 1
         AND tiInteractionTypeID = 2
         AND iInteractionOpenReasonID & 16 = 0
         AND iInteractionOpenReasonID & 4 = 0
         AND iInteractionID NOT IN …
