read committed snapshot with table hint updlock

    Hi,

    Got the following query from our developers.
    Kindly help me resolve if you can.

    The database is set for "read committed snapshot".
    It seems that a Select with updlock should not block another Select, but it does.

    If we give Transaction 1 as:
    begin tran
    select * from T1 with (updlock)

    and Transaction 2 as:
    select * from T1

    Then Transaction 2 is blocked.

    Any ideas?

    Thanks!

    You put an updlock on a table and then want to read from it in a separate transaction?   That just doesn't make any sense.   tablock, perhaps, but not updlock.
