基于row模式的binlog,生成DML(insert/update/delete)的rollback语句
通过mysqlbinlog -v 解析binlog生成可读的sql文件
提取需要处理的有效sql
"### "开头的行.如果输入的start-position位于某个event group中间,则会导致"无法识别event"错误
将INSERT/UPDATE/DELETE 的sql反转,并且1个完整sql只能占1行
INSERT: INSERT INTO => DELETE FROM, SET => WHERE
UPDATE: WHERE => SET, SET => WHERE
DELETE: DELETE FROM => INSERT INTO, WHERE => SET
用列名替换位置@{1,2,3}
通过desc table获得列顺序及对应的列名
特殊列类型value做特别处理
逆序
注意:
表结构与现在的表结构必须相同[谨记]
由于row模式是幂等的,并且恢复是一次性,所以只提取sql,不提取BEGIN/COMMIT
只能对INSERT/UPDATE/DELETE进行处理
