I’m having a problem in grouping and sorting data in our daily time record

I’m having a problem in grouping and sorting data in our daily time record
to automatically produce a report.
The table structure of the DTR as follows:

Log Date    Log Time    Employee Name           Log Type
9/13/2012   17:00:00    SALITA, LYNYRD ANTONIO  LOGOUT
9/13/2012   8:05:00     SALITA, LYNYRD ANTONIO  LOGIN
9/12/2012   17:05:00    SALITA, LYNYRD ANTONIO  LOGOUT
9/12/2012   8:05:00     SALITA, LYNYRD ANTONIO  LOGIN
7/10/2012   17:00:00    GARCIA, ALVIN           LOGOUT
7/10/2012   17:00:00    AURENO, LEAH            LOGOUT
7/10/2012   17:00:00    SALITA, LYNYRD ANTONIO  LOGOUT
7/10/2012   17:00:00    CANSINO, PAUL           LOGOUT
7/10/2012   17:00:00    BELO, RIO               LOGOUT
7/10/2012   17:00:00    MAG-ISA, MAYBELLE       LOGOUT
7/10/2012   17:00:00    TARINE, KAREN           LOGOUT
7/10/2012   17:00:00    REYES, ANDREA           LOGOUT
7/10/2012   17:00:00    NAVARRO, KRISTINA       LOGOUT
7/10/2012   10:30:00    MAG-ISA, MAYBELLE       LOGIN
7/10/2012   8:00:00     SALITA, LYNYRD ANTONIO  LOGIN
7/10/2012   8:00:00     CANSINO, PAUL           LOGIN
7/10/2012   8:00:00     BELO, RIO               LOGIN
7/10/2012   7:40:00     AURENO, LEAH            LOGIN
7/10/2012   7:30:00     GARCIA, ALVIN           LOGIN
7/10/2012   7:25:00     TARINE, KAREN           LOGIN
7/10/2012   7:10:00     NAVARRO, KRISTINA       LOGIN
7/10/2012   7:10:00     REYES, ANDREA           LOGIN

I want it to be processed as a query with an output like this:

Log Date    Employee Name           LOGIN       LOGOUT
9/13/2012   SALITA, LYNYRD ANTONIO  8:05:00     17:00:00
9/12/2012   SALITA, LYNYRD ANTONIO  8:05:00     17:05:00
7/10/2012   GARCIA, ALVIN           7:30:00     17:00:00
7/10/2012   AURENO, LEAH            7:40:00     17:00:00
7/10/2012   SALITA, LYNYRD ANTONIO  8:00:00     17:00:00
7/10/2012   CANSINO, PAUL           8:00:00     17:00:00
7/10/2012   BELO, RIO               8:00:00     17:00:00
7/10/2012   MAG-ISA, MAYBELLE       10:30:00    17:00:00
7/10/2012   TARINE, KAREN           7:25:00     17:00:00
7/10/2012   REYES, ANDREA           7:10:00     17:00:00
7/10/2012   NAVARRO, KRISTINA       7:10:00     17:00:00

How do I achieve this?

    This is what you are trying to get:

    SELECT DATE_FORMAT(LogDate, '%d/%c/%Y') AS LogDate, EmployeeName,
   (GROUP_Concat(CASE LogType WHEN 'LOGIN' THEN LogTime END)) AS LOGIN,
   (GROUP_Concat(CASE LogType WHEN 'LOGOUT' THEN LogTime END)) AS LOGOUT
FROM myTable
GROUP BY LogDate, EmployeeName
ORDER BY LogDate desc;

    See this SQLFiddle

    Description of the query:

    Use CASE Statement to convert row to column (for Login and Logout)

    SELECT DATE_FORMAT(LogDate, '%d/%c/%Y') AS LogDate, EmployeeName,
   (CASE LogType WHEN 'LOGIN' THEN LogTime END) AS LOGIN,
   (CASE LogType WHEN 'LOGOUT' THEN LogTime END) AS LOGOUT
FROM myTable
GROUP BY LogDate, EmployeeName, LogTime
ORDER BY LogDate desc;

    But this will result you like in this SQLFiddle.

    So you need to use GROUP_CONCAT (MySQL) to join LogTime with NULL and remove LogTime from GROUP BY clause.
