关于Mysql 特殊字符\\\%，怎么理解呢？
我表的字符字段里有三个记录
a%
a\
a\asdf
>SELECT * FROM ccs.username where name LIKE 'a\%';
a%
问题:
>SELECT * FROM ccs.username where name LIKE 'a\\%';
a%
为何不返回a\,a\asdf呢，而\\%跟\%的意义一样呢？
>SELECT * FROM ccs.username where name LIKE 'a\\\%';
a\
a\asdf
a%
a\
a\asdf
>SELECT * FROM ccs.username where name LIKE 'a\%';
a%
问题:
>SELECT * FROM ccs.username where name LIKE 'a\\%';
a%
为何不返回a\,a\asdf呢，而\\%跟\%的意义一样呢？
>SELECT * FROM ccs.username where name LIKE 'a\\\%';
a\
a\asdf
