MySQL误操作恢复的完全指南

SHOW VARIABLES LIKE 'log_bin';              -- 必须为 ON
SHOW VARIABLES LIKE 'binlog_format';        -- 必须为 ROW
SHOW VARIABLES LIKE 'log_bin_basename';     -- 获取 binlog 文件存储路径前缀

SHOW BINARY LOGS;

cd /d "D:\base\mysql8\bin"
mysqlbinlog --base64-output=decode-rows -vv "D:\base\mysql8\Data\DESKTOP-H12BE21-bin.000201" | findstr "Start time"

mysqlbinlog --base64-output=decode-rows -vv "D:\base\mysql8\Data\DESKTOP-H12BE21-bin.000201" | findstr "#230402"

mysqlbinlog --base64-output=decode-rows -vv --start-datetime="2026-04-02 14:50:00" --stop-datetime="2026-04-02 15:10:00" "D:\base\mysql8\Data\DESKTOP-H12BE21-bin.00020*" > D:\binlog_scan.txt

copy "D:\base\mysql8\Data\DESKTOP-H12BE21-bin.000201" D:\my2sql\my2sql-master\

cd /d D:\my2sql\my2sql-master

-- 检查误操作标记字段是否已恢复
SELECT COUNT(*) FROM order_ai_record WHERE DELETE_FG = '1';
-- 抽查特定记录
SELECT * FROM order_ai_record WHERE ID = 11675;

1. 确认 binlog 开启且为 ROW 格式
   ↓
2. SHOW BINARY LOGS 列出所有文件
   ↓
3. 用 mysqlbinlog 扫描文件时间范围 → 定位误操作对应的 binlog 文件
   ↓
4. 复制 binlog 文件到 my2sql 目录
   ↓
5. 使用 my2sql 生成回滚 SQL（指定 -work-type rollback 和时间范围）
   ↓
6. 检查生成的 rollback.xxx.sql 文件内容
   ↓
7. 执行回滚 SQL 恢复数据
   ↓
8. 查询验证数据是否恢复正确

-- 1. 开启事务
BEGIN;

-- 2. 先查询影响范围
SELECT * FROM order_ai_record WHERE ID = 11675;

-- 3. 执行更新/删除
UPDATE order_ai_record SET DELETE_FG = '1' WHERE ID = 11675;

-- 4. 再次确认
SELECT * FROM order_ai_record WHERE ID = 11675;

-- 5. 确认无误再提交
COMMIT;

-- 如果发现错误，立即回滚
ROLLBACK;
