Enterprise Architect 修改模板，适应mysql生成ddl

Enterprise Architect 修改模板，适应mysql生成ddl

版本：Enterprise Architect 12

前言：Enterprise Architect可以导入DDL，直接生成相应的图像，通过可视化的界面给呈现相应的数据库，但是通过实验，发现它对mysql数据库的支持非常有限，所以本人对之前的模板进行了修改，从而导出的DDL可以直接导入数据库中建表

1、导入mysql的数据源

2、建立mysql的主外键关系

3、修改ddl模板

细解：

1、Enterprise Architect读取的数据源，真正所在的位置在C:\Windows\SysWOW64\odbcad32.exe上面，

我们安装mysql 64位数据源ODBC的时候安装到了C:\Windows\System32\odbcad32.exe这里，所以出现了不匹配

解决方案：

参考网上的，下载mysql odbc 32位的，然后打开C:\Windows\SysWOW64\odbcad32.exe的文件，添加相应的数据源

2、mysql的主外键关系

工具箱中拖入Assosition，从包含外键的表指向来源的表，然后编辑相应的字段

3、ddl模板

出现问题：

如果字段不需要定义长度，例如timestamp，则有个0

SET FOREIGN_KEY_CHECKS=0后面没有分号，同1

没有default值

有对于数据库名的强引用，不方便加表

comment值被隐藏

解决：

修改模板

菜单栏–>包–>数据库工程–>修改ddl模板–>找相应的类并替换

comment

在导出时 格式–>评语水平–>全部
