No, at least not as you expect it. SQL returns the found records in
random order except for the explicit "order by" clause. So if you want a
chronological order, you have to supply some ordering fields to the
order by clause. This could be achieved easily by normalizing your
table, i.e. create a table like:
create table ages (
age_id smallint primary key,
sort_order smallint,
age_name varchar(100)
);
insert into ages values (1, 10, 'childhood');
insert into ages values (2, 20, 'high school');
insert into ages values (3, 30, 'univesrity');
NOTE: leave gaps in the sort order to accommodate for later insertions.
Then in the original table replace the names with age_id, and use a join
on the 2 tables, sorting by original_table.person_id, ages.sort_order.
