我已经使用C#和SQL 2008设计了Windows应用程序。 现在,我想控制用户可以访问哪个部分及其权限。

所以,我想知道在sql中设计表并为每个用户设置权限还是有其他解决方案更好?

答案 0 :(得分:0)

一般来说,我所看到的是以下几点:

tblUser表格,如下所示:

tblUser
    UserId
    UserName
    etc...

角色表:

tblRole
    RoleId
    Name

和链接表:

tblUserRole
    UserId
    RoleId

在您的应用程序中,您将检查当前用户是否在tblUserRole表中具有相应的角色。如果是,请允许当前用户使用该功能,否则显示错误消息,禁止用户输入等...

例如,在MS SQL中,您可以使用以下类型的Stored Procedure

添加用户

CREATE PROCEDURE spAddUser
    @UserName AS nvarchar(256)
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

INSERT INTO tblUser
    (UserName)
    VALUES(@UserName)

SELECT SCOPE_IDENTITY( ) AS 'Id'
END
GO

添加用户角色

CREATE PROCEDURE spAddUserRole
@UserId AS int,
@RoleId As int
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

INSERT INTO tblUserRole
    (UserId, RoleId)
    VALUES(@UserId, @RoleId)
END
GO

用户是否有角色

CREATE PROCEDURE spDoesUserHaveRole
@UserId AS int,
@RoleId As int,
@HasRole AS bit OUTPUT
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

SELECT @HasRole = COUNT(UserId) > 0 FROM tblUserRole
    WHERE UserId = @UserId AND
          RoleId = @RoleId
END
GO
