字符集和排序规则之间是不可以随便搭配的、如果你想知道一个字符集它所搭配的排序规则有哪些?那就可以从information_schema.collation_character_set_applicability

这个表来看

 

1、information_schema.collation_character_set_applicability 常用列说明:

  1、character_set_name                :字符集名

  2、collation_name                    :排序规则名

 

2、例子:

测试字符集和与之匹配的排序规则

select 
    character_set_name,collation_name 
from 
    information_schema.collation_character_set_applicability
order by
    character_set_name;
