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
