BUG #: 16273 (NT: 6.5)
SYMPTOMS
If you open a KEYSET cursor with the locking option UPDLOCK through sp_cursoropen in a transaction, only a shared lock is set on the pages with the qualifying data rows. With the first sp_cursorfetch, an Update_page lock is set.
This leads to a good chance to run into a deadlock.
WORKAROUND
To work around this problem, do either of the following:
- Use a DYNAMIC or FORWARD-ONLY cursor.
-or-
- Use TABLOCK or HOLDLOCK instead of UPDLOCK as optional optimizer hints in the FROM clause.
