    Dear Madhivanan

    I read it in Sql Server Help File.
    Following Are The Results

    Row Lock

    Use row-level locks instead of the coarser-grained page- and table-level locks.

    UPDLOCK

    Use update locks instead of shared locks while reading a table, and hold locks until the end of the statement or transaction. UPDLOCK has the advantage of allowing you to read data (without blocking other readers) and update it later with the assurance that the data has not changed since you last read it.

    This defintions are not helping me in finding out the difference between the two

    If you have got some other links kindly let me know

    Deep Regards
    Anil
