The framework calls this member function to get the default SQL statement on which the recordset is based.
virtual CString GetDefaultSQL( );
A CString that contains the default SQL statement.
This might be a table name or a SQL SELECT statement.
You indirectly define the default SQL statement by declaring your recordset class with ClassWizard, and ClassWizard performs this task for you.
If you pass a null SQL string to Open, then this function is called to determine the table name or SQL for your recordset.
