Help ! how to recover table data in sql 2005

Hi,
SQL server keeps log for every transation.So you can recover your modified data from the log as well without backup.
Here is the sample source code.

Select [PAGE ID],[Slot ID],[AllocUnitId],[Transaction ID],[RowLog Contents 0], [RowLog Contents 1],[RowLog Contents 3],[RowLog Contents 4]
,[Log Record]
FROM    sys.fn_dblog(NULL, NULL)  
WHERE
AllocUnitId IN 
(Select [Allocation_unit_id] from sys.allocation_units allocunits
INNER JOIN sys.partitions partitions ON (allocunits.type IN (1, 3)  
AND partitions.hobt_id = allocunits.container_id) OR (allocunits.type = 2 
AND partitions.partition_id = allocunits.container_id)  

Where object_id=object_ID('' + 'dbo.student' + ''))
AND Operation in ('LOP_MODIFY_ROW','LOP_MODIFY_COLUMNS') 
And [Context] IN ('LCX_HEAP','LCX_CLUSTERED')

Here is the artcile, that explains step by step, how to do it.
