python - 如何正确排序其中包含数字的字符串

Question

我有以下元素:

- Orange Is the New Black, Season 1, Ep. 1 -- I Wasn't Ready
- Orange Is the New Black, Season 1, Ep. 10 -- Bora Bora Bora
- Orange Is the New Black, Season 1, Ep. 2 -- Tit Punch

目前，我正在执行 SELECT title FROM table ORDER BY title。

我如何在 mysql 中正确排序？也就是说，所以结果是:

- Orange Is the New Black, Season 1, Ep. 1 -- I Wasn't Ready
- Orange Is the New Black, Season 1, Ep. 2 -- Tit Punch
- Orange Is the New Black, Season 1, Ep. 10 -- Bora Bora Bora

Answer 1

只要title字符串的格式没有改变，
可以在order by子句中使用substring_index和cast进行排序。

select * from table
order by
cast(SUBSTRING_INDEX( title, ', Ep. ', -1 ) as decimal);
