BUG #: 17161 (NT: 6.5)

SYMPTOMS

A dynamic or forward-only cursor opened with optimistic concurrency using either timestamps (OPTCC) or values (OPTCCVAL) will incorrectly hold a Sh_intent lock on the pages from which the rows were fetched. This problem occurs only if there is no unique index on the table.

WORKAROUND

To work around this problem, create a unique index on the table.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.5.

MORE INFORMATION

This problem does not occur with keyset or insensitive cursors because they default to read-only with no unique index.
