有。
自己写了一个。
给一组表名，生成一组实体类。
不过是C写的，生成的是一组实体结构。
有一组库函数来处理这些结构。

这组库函数以.hpp的形式转换成cpp。
实际上是带类的C。

支持的ORACLE，DB2，MYSQL。
其他数据库需要些驱动接口。
ODBC接口没写完就退休了。DB2接口与ODBC类似。

写个简单凑合用的，一天差不多。
最后弄完善了，哩哩啦啦弄了3～4年。
【 在 DoorWay 的大作中提到: 】
: 写个代码生成插件，4小时足够了吧

【 在 ylh0315 的大作中提到: 】
: 因为结构不能反射，所以C比较困难。
: 但是可以有办法解决。

$ mkpatt 表名
生成两个文件：
表名.stu，对应表名的数据结构，相当于.h文件。在某个.h include之。
表名.tpl，结构说明书，相当于一个.c文件。在某个.c文件include之。
