Derive CDatabase and override OpenEx. In your derived class CMyDatabase, replace the call to AllocConnect to MyAllocConnect. Obviously, your MyAllocConnect function should call SQLSetConnectOption with the desired parameter:

// Turn on cursor lib support
if (dwOptions & useCursorLib)
{
    AFX_SQL_SYNC(::SQLSetConnectOption(m_hdbc, SQL_ODBC_CURSORS, SQL_CUR_USE_ODBC));
    // With cursor library added records immediately in result set
    m_bIncRecordCountOnAdd = TRUE;
}

Then use your CMyDatabase class instead of CDatabase for all your queries.
