You can use ROW_NUMBER some thing like this
SELECT row_number() OVER (ORDER BY col1) n,
  FROM table1 

Open in new window

select row_number() OVER (ORDER BY b.col) n,distinct b.* from #Temp1 as a 
inner join #TempCourses as b on a.CourseId = b.Courseid and a.[Request Date] = b.[From Date]

Open in new window
