I have an issue that, while using sql server 2005 i have executed update query without where clause (by mistake) and all the original values of the column get lost.

How can I get old values??

Any suggestion/tips/solution is welcome and will be highly appreciated.

You need a SQL Transaction Log viewer.
Good news is that most of them are capable of undoing your mentioned last update command within a simple click:[^][^]

Bad news is that some of them are very expensive and some of them may not compatible with your SQL server version.

Hope it helps.

Thanks thatraja :)
Restore from your last backup is the first, best option - you do backup regularly, don't you?
Unfortunately, if you can't restore, then you need to restore from log files. Time to start reading (and praying...)[^]

I maintains backup but I did not took backup since last week and I have a dozen of updates in it within this time period. So is it possible to get the data back with your suggested solution ?

It may be - start reading, but don't expect it to be simple!

Right, 5!
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 [Context] IN   ('LCX_HEAP','LCX_CLUSTERED')

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