Detailed Description

    This is an example TTableRow subclass used to read rows of
    demonstration DEMO_DB_TABLE.  It can be used as the starting point
    for other subclasses.
    
    For table XXX_YYY (all tables names are upper case) the corresponding TTableRow subclass is
    
        ND::TXxx_Yyy  (arbitrary capitalisation).
    
    This is a demonstration table row

00030     }

void TDemo_DB_Table::Fill ( TResultInputStream & ris ) [virtual]

Required method to fill self from a ResultInputStream.

This method is used to fill a row. A ResultInputStream is an object with operator >> methods for most basic types.

Individual data items are read from it in the order in which they appear in the database table but notice that the first two rows (SEQNO and ROW_COUNTER) which are not part of the row's state, do not have to be skipped.

Also notice how the row state can include objects even though the stored state can only store basic types. E_CHAN_ID is stored as a MySQL INT but is used to fill a TTFBChannelId.

Reimplemented from TTableRow.
