SYMPTOMS

If multiple connections run concurrent single-row INSERT or UPDATE statements on a non-indexed table, although rare, the UPDATE might fail.

The UPDATE fails to complete with "0 rows affected" (and no other errors), when it should have succeeded, and the row is not updated.

WORKAROUND

Create either a clustered or non-clustered index on the table.
