MySQL中的自然排序

是否有一种优雅的方式在 MySQL 数据库中进行高性能、自然的排序?

Is there an elegant way to have performant, natural sorting in a MySQL database?

例如,如果我有这个数据集:

For example if I have this data set:

  • 最终幻想
  • 最终幻想 4
  • 最终幻想 10
  • 最终幻想 12
  • 最终幻想 12:Promathia 之链
  • 最终幻想冒险
  • 最终幻想起源
  • 最终幻想战术

任何其他优雅的解决方案,而不是将游戏名称拆分成它们的组件

Any other elegant solution than to split up the games' names into their components

  • 标题:《最终幻想》
  • 数字:12"
  • 副标题:Promathia 之链"
  • Title: "Final Fantasy"
  • Number: "12"
  • Subtitle: "Chains of Promathia"

确保它们按正确的顺序出现?(4 之后的 10,而不是 2 之前).

to make sure that they come out in the right order? (10 after 4, not before 2).

这样做很痛苦,因为时不时会有另一款游戏打破解析游戏标题的机制(例如战锤 40,000"、詹姆斯邦德 007")

Doing so is a pain in the a** because every now and then there's another game that breaks that mechanism of parsing the game title (e.g. "Warhammer 40,000", "James Bond 007")

推荐答案

我认为这就是为什么很多东西都按发布日期排序的原因.

I think this is why a lot of things are sorted by release date.

解决方案可能是在表中为SortKey"创建另一列.这可能是标题的经过清理的版本,它符合您为便于排序或计数器而创建的模式.

A solution could be to create another column in your table for the "SortKey". This could be a sanitized version of the title which conforms to a pattern you create for easy sorting or a counter.
