BUG #: 4797 (NT: ODBC30)


An ODBC application may get an access violation (AV) using the ODBC cursor library (Odbccr32.dll) if both of the following conditions are true:

  • It creates more than one CRecordset objects.


  • The following operations are done repeatedly on the CRecordset objects:

Open, MoveLast or Requery and Close.

The access violation error happens when the application tries to use the Close method of CRecordset or invoke the SQLFreeStmt ODBC function.


Microsoft has confirmed this to be a problem in Open Database Connectivity version 3.0. This problem has been corrected in Open Database Connectivity version 3.5.
