问题描述

我试图弄清楚我应该对各种类型的数据使用哪种排序规则.我将要存储的内容的100%是用户提交的.

I'm trying to figure out what collation I should be using for various types of data. 100% of the content I will be storing is user-submitted.

我的理解是,我应该使用UTF-8通用CI(不区分大小写),而不是UTF-8 Binary.但是,我找不到UTF-8通用CI和UTF-8 Unicode CI之间的明显区别.

My understanding is that I should be using UTF-8 General CI (Case-Insensitive) instead of UTF-8 Binary. However, I can't find a clear a distinction between UTF-8 General CI and UTF-8 Unicode CI.

  1. 我应该在UTF-8 General或UTF-8 Unicode CI列中存储用户提交的内容吗?
  2. UTF-8 Binary适用于什么类型的数据?

推荐答案

通常, utf8_general_ci utf8_unicode_ci 快,但正确性较低.

In general, utf8_general_ci is faster than utf8_unicode_ci, but less correct.

这是区别:

对于utf8_bin: utf8_general_ci utf8_unicode_ci 均执行不区分大小写的比较.相反, utf8_bin区分大小写(除其他差异外),因为它会比较字符的二进制值.

As for utf8_bin:Both utf8_general_ci and utf8_unicode_ci perform case-insensitive comparison. In constrast, utf8_bin is case-sensitive (among other differences), because it compares the binary values of the characters.
