整理是什么意思? [英] What does collation mean?

问题描述

排序规则在SQL中的含义是什么?

What does collation mean in SQL, and what does it do?

推荐答案

排序规则可以简单地认为是排序顺序.

Collation can be simply thought of as sort order.

用英语(这是一个很奇怪的堂兄，美国人)，排序规则可能很简单，只需按ASCII码排序即可.

In English (and it's strange cousin, American), collation may be a pretty simple matter consisting of ordering by the ASCII code.

一旦您带着所有重音和其他功能进入了这些奇怪的欧洲语言，排序规则就会发生变化.例如，尽管a的不同重音形式可能存在于不同的代码点，但它们可能都需要像它们是同一字母一样进行排序.

Once you get into those strange European languages with all their accents and other features, collation changes. For example, though the different accented forms of a may exist at disparate code points, they may all need to be sorted as if they were the same letter.
