I am having INOUT Table It have 5 record and 3 record is of 2011-07-2011

InOuT Table:

AutoId     FingerId      LogTime            Date
1            22          11:18:48 AM       2011-07-29

xyz             22        11:18:48 AM    11:19:54 AM   2011-07-29

I Want this type of OutPut:-

EmployeeName  FingerId   InTime         OutTime        Date

xyz             22        11:20:50 AM    11:21:54 AM   2011-07-21
xyz             22        11:21:59 AM    ----          2011-07-21  
xyz             22        11:18:48 AM    11:19:54 AM   2011-07-29

Here 2nd row is having InTime and i want outtime should display “—” dash.But i m not getting with this query. Query is correct but need to do modify for this.

I’ve made some modifications to your query which I’m posting now with the changes highlighted in bold:

;WITH cte AS
( 
  SELECT FingerId, [Date],
         LogTime,
         ROW_NUMBER() OVER(PARTITION BY FingerId ORDER BY LogTime) AS rn
  FROM InOut 
)
SELECT C3.EmployeeName,C1.FingerId,
       C1.LogTime AS InTime,
       C2.LogTime AS OutTime,
       COALESCE(C2.[Date], C1.[Date]) AS Date
FROM cte AS C1
  LEFT OUTER JOIN cte AS C2 ON C1.FingerId = C2.FingerId AND C1.rn + 1 = C2.rn
  INNER JOIN EmployeeMaster AS C3 ON C3.Fingerid = C1.Fingerid
WHERE C1.rn % 2 = 1
  AND C3.EmployeeName = 'xyz'
  AND C1.[Date] BETWEEN '2011-07-21' AND '2011-07-29'
ORDER BY C1.[Date]

Originally I was thinking about changing C1.[Date] in the SELECT clause to C2.[Date], but then I wasn’t sure it would be quite adequate a replacement in case the two dates were different. You can see for yourself which option is better, if any.
