INSERTINTO@Schedule

select'ABC',1,'22:01'unionALL

select'ABC',2,'05:01'unionALL

select'ABC',3,'14:01'unionALL

select'XYZ',1,'03:01'unionALL

select'XYZ',2,'12:01'unionALL

select'XYZ',3,'20:01'

Declare@DatasetNamesysname='XYZ'

Declare@StartTimedatetime='2014-01-19 01:21:39.000'

SelectRunID,@StartTime,CAST(CAST(@StartTimeASDATE)ASDATETIME)+CAST(StartMinTimeASTIME)

from@Schedulewhere Dataset=@DatasetName

andDATEPART(hour,cast(@StartTimeasTIME))>=DATEPART(hour,StartMinTime) andDATEPART(hour,cast(@StartTimeasTIME))<=(DATEPART(hour,StartMinTime)+ 8)
