如图新建“physical data model”,model name可以填项目1,选择DBMS。重命名“PhysicalDiagram_1”为基础数据。
如图,在项目上右击,选择“New”,再选“Table”,弹出窗口。
在表的基本属性中输入基本信息。
如图,编辑字段属性,如数据类型,是否主键等。有些字段属性默认是不显示的,如“默认值”属性,需要自行设置,点击图中漏斗状图标设置。
双击字段行,弹出字段详情窗口,如图,可以设置字段备注,字段自增等。
如图预览SQL。
如图,选中表后点击油漆桶图标,可以更改表的填充色;右侧的表格状图标也可以来建表。同时还可以建视图、外键关联等
如图,通过菜单“Tools”=>“Execute Commands”=>“Edit/Run Script”来执行脚本。

如图,通过菜单“Report”=>“Report Wizard”,生成RTF格式报告
如图,通过菜单“Database”=>“ChangeCurrent DBMS”更改DBMS
先准备好SQL脚本,然后如图,通过菜单“File”=>“Reverse Engineer”=>“Darabase”,弹出新建物理模型窗口,输入模型名称,选择DBMS。
点击“确定”按钮后,弹出逆向工程选项窗口,如图,选“Using script files”选项,点击添加文件按钮,添加SQL脚本文件,点击“确定”按钮,模型与表生成成功。
Options页的File encoding如图设置,防止中文备注乱码。
如图选择数据源,设置登录用户,之前的操作与SQL脚本方式一致。
登录用户的权限一定要恰当,如果用了root用户,则在下图中连系统表都出现了,勾选起来比较麻烦。点击“OK”按钮则开始逆向建模。
本次所用的PowerDesigner匹配的是32位的MySQL ODBC,一开始安装的是64位的,在配置里没有找到选项,改成32位后才出现MySQL选项。
