ddcw / ibd2sql

transform mysql ibd file to sql(data). 解析mysql中innodb数据文件(ibd),转换为sql. DDL和DML

介绍

ibd2sql是一个使用python3编写的离线解析MYSQL INNODB存储引擎的ibd文件的工具. 无第三方依赖包, 纯python3代码. 使用GPL-3.0 license.

特点

1. 方便: 提取表DDL
2. 实用: 可替换库(--schema)/表(--table)名, 可在sql语句中输出完整的字段(--complete)
3. 简单: 纯python3代码编写, 无依赖包.
4. 支持众多数据类型: 支持所有mysql数据类型
5. 支持复杂的表结构: 分区表, 注释, 主键, 外键, 约束, 自增, 普通索引, 前缀索引, 主键前缀索引, 唯一索引, 复合索引, 默认值, 符号, 虚拟字段, INSTANT, 无主键等情况的表
6. 数据误删恢复: 可以输出被标记为deleted的数据
7. 安全: 离线解析ibd文件, 仅可读权限即可
8. 支持范围广: 支持mysql 5.6 or 5.7 or 8.0 or 8.4

测试例子: docs/ALLTEST.md

ibd2sql's Issues

ibd2sql解析表结构DDL问题

解析表结果时，如果列类型 timestamp且有默认值是，建表语句
xx timestamp default 'current_timestamp' ,不需要''

如果blob/text字段，在key里面，会丢失，长度
key(xx,text) ---> key(xx,text(11))

说几个使用体验吧

1/首先感谢，在已经绝望的情况下，google看到了这个解决方案，虽然不能完美解决问题，但确实提供了许多帮助。
2/在可完全恢复的文件，从sql里面看到 decimal(10,2)的数据类型部分正确，部分变成超长的负数，大部分情况下代表的是0，还有一些null的情况变成一串0x....的长字符串
3/部分ibd文件无法恢复，只能恢复部分，一般是表字符CHARSET=utf8mb3，但实际表是完整无损的。
4/最后，其实我是在清理磁盘空间的时候，清空了undo_001,undo_002，最终发现把四个文件重命名undo_001,undo_002,ib_logfile0,ib_logfile1，重启mysql，重新生成了四个文件，数据都是原来的，一切都恢复正常了，当然可能部分提交中的数据有丢失也未知。

老铁，不是我说你，遮遮掩掩的。

你就完全支持嘛！搞什么适用于损坏恢复的ibd文件，其实就是只适应简单的损坏，严重觉得你就是沽名钓誉，有什么意思。 你把py搞成C代码不好吗？搞PY问题一大堆。

你好，mysql8.0 数据恢复有问题

执行命令：
python3 main.py /opt/user.ibd --debug --complete-insert --sql --delete
没有任何数据但是把--delete去掉后 可以恢复数据，但是我其实是使用delete from user 直接删除的。

你好，没有看到任何数据，在8.0里面生成的ibd 库名也要对应吗，我是从5.7导出create语句，在8.0执行的

能否可以支持自己指定表ddl创建语句

如果ibd 文件部分损坏，如sdi page 等page 异常，但是有表结构的场景

--sql 参数解析idb数据 varchar、text、int 、bigint类型解析出的数据有问题！

1、表结构

2、先查一下真实数据是什么

3、使用ibd2sql解析数据
$ python3.6 main.py /data0/mysqlsandbox/data/sandboxes/msb_8_0_33/data/testdb/dts_test_table.ibd --sql > /data0/dts_test_table.sql

4、看一下dts_test_table.sql里的id=100063数据是什么

老铁可以支持导出功能吗，导出来txt或者.sql格式的文件呢，谢谢

zlib.error: Error -3 while decompressing data: incorrect header check

first_blob 方法 解包异常

解析ibd文件，部分成功解析，解析过程有异常：
unpack requires a buffer of 12 bytes，如需要可提供ibd 文件

执行脚本解析ibd时，报编码错误

Traceback (most recent call last):

return bdata.decode()
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe4 in position 0: invalid continuation byte

恢复数据时报错RecursionError: maximum recursion depth exceeded，网上找了解决方案后执行不报错，但数据有缺失

老哥我这边执行时报这个错误，然后我在ibd2sql\mysql_json.py加了sys.setrecursionlimit(2000)，运行不报错，但生成的sql文件明显有数据缺失，这个问题咋解决呢

--ddl 生成错的 `!hidden!_dropped_v1_p13_status` NULL, 这怎么解决

修改一下能用了
for colid in self.column:
# ------
col = self.column[colid]
if '!hidden!' in col['name']:
continue
ddl += self._ci
# ---------
ddl += f"{col['name']} {col['type']}" #column name
if self.COLUMN_COLL and col['type'] != 'int':

对bigint数据类型支持好像有问题

bigint类型数据做ddl里是正常能解析出来的，但是在数据里bigint类型数据都是None，而且主键字段好像也没有生成ddl标识，可以优化吗

感激，分分钟解决问题

用 ibd2sql 解决了表内数据误删问题，找回了数据。万分感谢！

一个小建议，命令的 usage 输出可调整一下：

usage: main.py [-h] [--version] [--ddl] [--sql] [--delete] [--complete-insert] [--force] [--set] [--multi-value] [--replace]
               [--table TABLE_NAME] [--schema SCHEMA_NAME] [--sdi-table SDI_TABLE] [--where-trx WHERE_TRX]
               [--where-rollptr WHERE_ROLLPTR] [--where WHERE] [--limit LIMIT] [--debug] [--debug-file DEBUG_FILE]
               [--page-min PAGE_MIN] [--page-max PAGE_MAX] [--page-start PAGE_START] [--page-count PAGE_COUNT]
               [--page-skip PAGE_SKIP] [--parallel PARALLEL]
               [FILENAME]

可改为

usage: 
main.py -h
main.py --version
main.py <FILENAME> [--ddl] [--sql] [--delete] [--complete-insert] [--force] [--set] [--multi-value] [--replace]
               [--table TABLE_NAME] [--schema SCHEMA_NAME] [--sdi-table SDI_TABLE] [--where-trx WHERE_TRX]
               [--where-rollptr WHERE_ROLLPTR] [--where WHERE] [--limit LIMIT] [--debug] [--debug-file DEBUG_FILE]
               [--page-min PAGE_MIN] [--page-max PAGE_MAX] [--page-start PAGE_START] [--page-count PAGE_COUNT]
               [--page-skip PAGE_SKIP] [--parallel PARALLEL]

这样与实际执行可保持一致，与 README.md 中的例子一致。

处置时紧张，一开始按 usage 中的文件名放最后方式去操作，没输出 sql。冷静后反复尝试才发现需要将文件名前置。

最后，再说一次，感谢！！！

执行命令的时候报错 row_format = compressed or its damaged or its mysql 5.7 file

两个版本的试了
我的mysql版本是8.0
为什么报这个错误?: row_format = compressed or its damaged or its mysql 5.7 file

可以加你联系方式吗?

3、使用工具解析5.7的数据

datetime、int类型的数据解析异常

我在解析数据的时候，发现datetime类型和int类型的数据解析有问题。会成-3954-2-26 3:20:54、-1257699829类似的这种格式。请问这个要怎么修复呀

非常好用，生成sql希望支持longtext和longblob类型。这两个在插入语句用字符串插入就可以
