SYMPTOMS
You may receive an access violation under rare conditions
when the following are true:
- Your program calls the UpdateBatch method of an ActiveX Data Objects (ADO) Recordset object.
- The connection that the Recordset object uses is made by using the Microsoft OLE DB Provider for ODBC drivers in
Microsoft Data Access Components (MDAC).
You may see a call stack that is similar to the following if
you capture the access violation exception with a debugger or in a dump file:
msdasql!CUpdateQueryBased::ClusterRows+0x142
msdasql!CUpdateQueryBased::Update+0x181
msdasql!CImpIRowsetUpdate::Update+0x44c
msadrh15!CRowsetHelper::Update+0x5d
msado15!CRecordset::_UpdateBatch+0x21b
msado15!CRecordset::UpdateBatch+0x8e
<your program function
calls>
This problem does not occur in other OLE DB providers.
