Question

I am sorry if the question is silly because i’m new to SQL Server. I want to select top 5 records for each day of specified month.
e.g.

top 5 records for day 1 in month september
top 5 records for day 2 in month september
top 5 records for day 3 in month september
.
.
top 5 records for day 31 in month september

and show these all records as a one result.

Answer 1

Let’s say you’re checking speeding records for the month June 2012, and you wanted the top 5 speeds (by speed desc).

SELECT *
  FROM (
    SELECT *, RowNum = Row_number() over (partition by Cast(EventTime as Date)
                                          order by Speed desc)
      FROM Events
     WHERE EventTime >= '20120601'
       AND EventTime <  '20120701'
  ) X
 WHERE RowNum <= 5
