FIX: AV If Extended Cursor Opens SP Without Execute Permission

ID: Q162906

The information in this article applies to:

Microsoft SQL Server version 6.5

BUG #: 16434 (6.5)

SYMPTOMS

A handled access violation (AV) may occur if an extended cursor (not a Transact-SQL ANSI cursor) is opened on a stored procedure to which you do not have execute permission. For example, suppose in a Visual Basic program using the Remote Data Objects (RDO) interface, you call the function OpenResultSet on a stored procedure. OpenResultSet in turn calls the ODBC function SQLExecDirect, which then calls sp_cursoropen. If this is called on a stored procedure to which you do not have execute permission, you may receive a handled AV in xpcursordeclare().

WORKAROUND

Ensure all necessary permissions are granted on stored procedures in the database. Under some conditions, it may be necessary to drop and re-create the stored procedures before granting permissions on them.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.5. This problem has been corrected in U.S. Service Pack 3 for Microsoft SQL Server version 6.5. For more information, contact your primary support provider.
