Let's get back to the basics of an RDBMS. Rows are not records; fields
are not columns; tables are not files; there is no sequential access or
ordering in an RDBMS, so "first", "next" and "last" are totally
meaningless. If you want an ordering, then you need to have a column
that defines that ordering. You must use an ORDER BY clause on a
cursor or in an OVER() clause.

You can help yourself by doing about one week's worth of reading on
RDBMS. You are making a fool of yourself by not knowing the basics.
