Query to fetch in-out time for all employees from one table

I need to find first in and last out time for all employees from a table. I have tried the following query.

select 
  attDate, 
  min(cast(attTime as time)) AS 'inTime',  
  max(cast(attTime as time)) AS 'outTime' 
from EmployeePunch 
where attDate between @minAttDate 
     and @maxAttDate and accessCardNum = 121 
group by attDate 
ORDER BY attDate asc

This query return the records for a particular employee. But I have to find the data for all employees.

Sample Table data:

Sno.attDate     attTime             accessCardNum

Answer

you can use this.

SELECT 
    accessCardNum,
    attDate, 
    MIN(CAST(attTime AS TIME)) AS 'inTime', 
    MAX(CAST(attTime AS TIME)) AS 'outTime' 
FROM EmployeePunch 
WHERE attDate BETWEEN @minAttDate AND @maxAttDate     
GROUP BY accessCardNum, attDate 
ORDER BY accessCardNum, attDate
