角色权限设计解决方案

一、表的说明

1具权限项掩码表：包括字段  ID，权限类别，权限明细，权限码，下属权限码 等

权限码 用二进制数为标志 如1 2 4 8 16等

下属权限码 是该权限所包含的统一权限类别的其他的权限 用二进制数表示

权限明细与权限码保持一致 但是用字符串表示 如edit delect 等

权限类别是某一功能的表示  如client 等

2 角色表：包括字段，ID，角色名，角色的描述 等

3权限表：ID，权限类别，权限码总和

权限类别 跟权限表的权限类别关联

权限码总和 是指同一权限类别的权限总和（用二进制表示权限码的意义就是能够通过权限码的总和可以分出具体的那些权限）

4 用户表：包括三个或以上字段，ID，用户名，对该用户的描述，其它（如地址、电话等信息）；

5用户部门表：包含 ID，部门编号，部门名称 等

6部门-角色-用户表  ID，部门ID，角色ID，用户ID

用来解决一个用户多部门多角色的问题  同一个职员在一个部门也可以拥有多个角色

如  用户1-部门1-角色1

    用户1-部门2-角色1

   用户1-部门3-角色2

等等

二、程序解决方法

1具权限项掩码表

GO
if exists (select 1
            from  sysobjects
           where  id = object_id('t_Object')
            and   type = 'U')
   drop table t_Object
GO
create table  t_Object(
    FObjectno            varchar(40)        not null,
    FObjectgroup         varchar(40)        not null,
    FObjectorder         int                not null,
    FSysID               varchar(40)        not null   default ('system'),
    F0bjectdetail        nvarchar(40)       not null   default (''),
    FAccessmask          bigint             not null   default ((0)),
    FAccessinclude       bigint             not null   default ((0)),
    FServicetype         nvarchar(20)       not null   default (''),
    FObjectid            bigint             not null,
