FIX: Error 231 After Opening a Server Side Cursor

 Last reviewed: October 29, 1997
Article ID: Q165621
The information in this article applies to:
  • Microsoft SQL Server, version 6.5
  • Microsoft SQL Server driver, version 2.65
  • Microsoft Open Database Connectivity, versions 2.5 and 3.0
BUG #: 16328 (2.65.0240)

SYMPTOMS

In a multi-threaded application that has two threads, when the first thread does a SQLExecDirect of a select statement and the second thread does a SQLCancel in the middle of the select, the driver does not get a response back from the server, and therefore closes the connection.

The following error is reported by the Net-Library: 

   Error 231: ConnectionTransact (GetOverLappedResult()).
The SQL Server driver then reports the following error: 

   szSqlState = "08S01", *pfNativeError = 0, *pcbErrorMsg = 61
   szErrorMsg = "[Microsoft][ODBC SQL Server Driver]Communication link
   failure"

WORKAROUND

There is no known workaround at this time.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server driver version 2.65. 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.
