本文介绍

导出数据库建表语句
导出数据库表备注（alter table 语句），并和步骤1内容合并到sql文件
将合并后的sql文件导入powerdesigner
powerdesigner中使用脚本运行设置entity字段列内容（字段中文名、字段英文名、字段类型、索引类型）
（设置列内容脚本见文末）
powerdesigner中使用脚本运行将entity模型导出生成数据库字典到Excel
（生成Excel脚本见文末）

概念

msyql排序规则
utf-8有默认的排序规则，查看命令

show charset like 'utf8%';

utf8_general_ci
不区分大小写，这个你在注册用户名和邮箱的时候就要使用。
utf8_general_cs
区分大小写，如果用户名和邮箱用这个就会造成不良后果。
utf8_bin
字符串每个字符串用二进制数据编译存储，区分大小写，可以存二进制的内容。

概述：utf8_unicode_ci比较准确，utf8_general_ci速度比较快。通常情况下 utf8_general_ci的准确性就够我们用的，在我看过很多程序源码后，发现它们大多数也用的是utf8_general_ci，所以新建数据库时一般选用utf8_general_ci就可以。

整理数据库表字典

导出表结构（示例使用Navicat），示例如下。

//树状菜单表
CREATE TABLE `demo_menu` (
`id`  varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL COMMENT '主键' ,
`pid`  varchar(36) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '父级菜单id' ,
`name`  varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '菜单名称' ,
`code`  varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '菜单编码' ,
`pcode`  varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '父级菜单编码' ,
`type`  varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '菜单类型' ,
`icon`  varchar(150) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '菜单图标' ,
`priority`  int(11) NULL DEFAULT NULL COMMENT '展示顺序' ,
PRIMARY KEY (`id`)
)
ENGINE=InnoDB
DEFAULT CHARACTER SET=utf8 COLLATE=utf8_general_ci
COMMENT='菜单表'

;

整理数据库表备注，示例如下。

//导出语句
select
    concat(
        'alter table ',
        t.table_name,
        ' comment \'',
        t.table_comment,
        '\'',
        ';'
    ) as '表格备注'
from
    information_schema.`tables` t
where
    t.table_schema like '%demo_databases%'
and t.table_name like '%demo_menu%';


//导出结果
alter table demo_menu comment '菜单表';
alter table demo_user comment '用户表';

3.将第1步导出结果和第1步结果合并到demo.sql文件。
4.使用powerdesigner导入demo.sql，如下图。

调整entity字段中文。

6.导出数据库字典到Excel
上述代码。

代码示例，调整entity字段中文

      MsgBox   "There   is   no   current   Model " 
ElseIf   Not   mdl.IsKindOf(PdPDM.cls_Model)   Then 
      MsgBox   "The   current   model   is   not   an   Physical   Data   model. "

      ProcessFolder   mdl

      Dim   Tab   'running     table 
      for   each   Tab   in   folder.tables 
            if   not   tab.isShortcut   then 
                  tab.name   =   tab.comment
                  Dim   col   '   running   column 
                  for   each   col   in   tab.columns 
                  if col.comment="" then
                  else
                        col.name=   col.comment 
                  end if
                  next 
            end   if 
      next

      Dim   view   'running   view 
      for   each   view   in   folder.Views 
            if   not   view.isShortcut   then 
                  view.name   =   view.comment 
            end   if 
      next

      '   go   into   the   sub-packages 
      Dim   f   '   running   folder 
      For   Each   f   In   folder.Packages 
            if   not   f.IsShortcut   then 
                  ProcessFolder   f 
            end   if 
      Next 
end   sub
