Tips

If you want to use .net code, please create a file name config.ini, and add your own MySql information such as:

[mysql]
server = "your server"
database = "the database you want to use"
UID = "user"
PWD = "password"
port = "port"

吐槽

PowerDesigner添加外键的时候，如果想要自动将主表的主键添加到从表的属性里，从表任一属性的code不能和主表的主键code相同。

例：reader_category(id, ...)和reader_info(id, ...)这种命名方式不行。
