这是我的 NEWSPAPER 表。
    National News   A   1
    Sports          D   1
    Editorials      A   12
    Business        E   1
    Weather         C   2
    Television      B   7
    Births          F   7
    Classified      F   8
    Modern Life     B   1
    Comics          C   4
    Movies          B   4
    Bridge          B   2
    Obituaries      F   6
    Doctor Is In    F   6
当我运行这个查询
select feature,section,page from NEWSPAPER
where section = 'F'
order by page;
它给出了这个输出
Doctor Is In    F   6
Obituaries      F   6
Births          F   7
Classified      F   8
但是在 Kevin Loney 的 Oracle 10g Complete Reference 中,输出是这样的
Obituaries      F   6
Doctor Is In    F   6
Births          F   7
Classified      F   8
请帮助我了解它是如何发生的?
