APPLIES TO


This article was previously published under Q165621
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.
