When we update , the DataSet helps out with the process,
because it keeps track of multiple versions of rows that
have been updated. You can use parameters to set the
CommandText property of DataAdapter's UpdateCommand. The
SqlParameter class contains a property, called RowVersion,
that informs the DataSet which version of the value to make
use of. The DataAdapter judges whether the update worked by
considering whether the UPDATE statement have an effect on
zero or a non-zero number of rows. If someone else has
changed design (or deleted the row), the UPDATE returns "0
rows affected." If no one else touched the row (that is,
your optimism was justified), you receive "1 row affected."
