BUG #: 18014 (SQLBUG_65)

Expand all | Collapse all

SYMPTOMS

If you use a keyset, dynamic, or forward-only cursor on a query that is based on a derived table, an access violation (AV) may occur. Insensitive cursors do not cause the access violation. On the client, the query will not complete, and when the query is canceled, the following error message is displayed:

Query canceled by User
DB-Library: Possible network error: Error in sending out-of-band data to SQL Server.
Net-Library error 232: ConnectionWrite (GetOverLappedResult()).

WORKAROUND

To avoid the access violation, either do not use a derived table or change the cursor type to insensitive.
