    Hello Sarvana Perumal,

    You can use Triggers. Refer about the same on MSDN Code Library on below mentioned link :

    Hope this will help you.

    You can try this Query

    Select Ename from Table1 where Ename<>
    (Select Ename from Table1)

    Thanks for your reply.. Got Code for this.. here by I post

    declare @action_field varchar(max)

    SELECT @action_field = Isnull(@action_field + ', ', '') + name
    FROM syscolumns
    WHERE id = (select object_id from sys.tables where name = 'tablename)
    AND CONVERT(VARBINARY, Reverse(Columns_updated())) & Power(CONVERT(BIGINT, 2), colorder - 1) > 0

    The above code capture the updated column value with comma separated value.

    Thanks & Regards
