CRecordset::m_pDatabase
Contains a pointer to the CDatabase object through which the recordset is connected to a data source.
Remarks
This variable is set in two ways. Typically, you pass a pointer to an already connected CDatabase object when you construct the recordset object. If you pass NULL instead, CRecordset creates a CDatabase object for you and connects it. In either case, CRecordset stores the pointer in this variable.
Normally you will not directly need to use the pointer stored in m_pDatabase. If you write your own extensions to CRecordset, however, you might need to use the pointer. For example, you might need the pointer if you throw your own CDBExceptions. Or you might need it if you need to do something using the same CDatabase object, such as running transactions, setting timeouts, or calling the ExecuteSQL member function of class CDatabase to execute SQL statements directly.
