适合先有数据库结构，后需要导出数据字典的情况，多数在发开完成交文档或者用户有库的情况下
有条件的话推荐用powerdesigner导出，比较好看
如果用powerdesigner导出的注释不对，是因为数据库的编码不对
1、使用navicat导出
在该数据库下新建一个查询输入下面的语句
SELECTTABLE_NAME 表名称,COLUMN_NAME 列名称,COLUMN_DEFAULT 默认值,IS_NULLABLE 是否为null,COLUMN_TYPE 数据类型,COLUMN_KEY 索引,EXTRA 其他属性,COLUMN_COMMENT 注释
FROMinformation_schema.COLUMNS
WHERETABLE_SCHEMA = '数据库名'
查询结果如下
导出结果到本机电脑里
修改一下名字后保存
然后再按照自己想要的格式进行调整或者粘到word
其他的可选字段及注释
2、使用 powerdesigner 导出数据字典
连接数据库方式在此不赘述了，只谈导出
打开菜单Tools>Execute Commands>Edit/Run Script… 或者用快捷键 Ctrl+Shift+X，复制下列代码，粘贴

运行完会自动打开Excel
powerdesigner导出来的会比上一种方法导出来的好看
