STR( MIN(if DATETRUNC(day, [Order Date])>= [Start Date] THEN [Order Date] END)) + +STR(MAX(IF DATETRUNC(day, [Order Date])<=([End Date]) THEN [Order Date] END )), STR( MIN(if DATETRUNC(day, [Order Date])>=DATEADD(day,-[Days Inbetween SD and ED],[Start Date]-1) THEN [Order Date] END)) + + STR( MAX(IF DATETRUNC(day, [Order Date])<=([Start Date]-1) THEN [Order Date] END)).
