mysql根据binlog恢复数据

创建表

mysql> CREATE TABLE `test` (
                              `id` int(11) NOT NULL AUTO_INCREMENT,
                              `price` int(10) DEFAULT NULL,
                              PRIMARY KEY (`id`)
                          );
Query OK, 0 rows affected

mysql> desc test;
+-------+---------+------+-----+---------+----------------+
