Ⅰ. Issue Description

1、当前的前置镜像SQL语句查询条件是通过在插入语句中找出唯一索引或主键值构造的，当主键自增且无唯一索引的情况下，就没有查询条件了，导致查询出了所有数据，实际前置镜像应该为空
eg：
CREATE TABLE t_nounique (
id int auto_increment,
a int DEFAULT NULL,
b int DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4
insert into t_nounique(id,a,b) values(3,3) on duplicate key update b = 5
2、当前后置镜像SQL语句查询条件是通过前置镜像SQL语句加上前置镜像结果中的主键值来构造的，没有考虑主键自增且无前置镜像的情况。建议后置镜像的查询条件逻辑修改为：先通过前置镜像SQL找到的主键值+前置镜像主键值去重组合，若组合的列表为空，再查找到插入后的自增主键值
