权限管理模块管理

权限管理，不但有角色大方面来控制用户所拥有的权限，还是以模块来控制，这样可以让权限分得更细些。
这方法与角色管理表结构与存储过程是一样的，只是一些表名写字段名称不一样而已。
在asp.net后台管理介面如下截图：

数据表[Module]结构如下：

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[Module](
    [ModuleId] [smallint] IDENTITY(1,1) NOT NULL,
    [ModuleName] [nvarchar](50) NOT NULL,
    [Description] [nvarchar](100) NOT NULL,
PRIMARY KEY CLUSTERED 
(
    [ModuleId] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY],
 CONSTRAINT [UK_Module_UD980sA6] UNIQUE NONCLUSTERED 
(
    [ModuleName] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

插入存储过程usp_Module_Insert：

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[usp_Module_Insert]
(
    @ModuleName nvarchar(50),
    @Description nvarchar(50)
)
AS    
 SELECT [ModuleName] FROM [Module] WHERE [ModuleName]=@ModuleName
IF @@ROWCOUNT>0
BEGIN
    RAISERROR(N'此模块已经存在，无法添加！',16,1)
    RETURN
END
ELSE

  BEGIN TRANSACTION
            INSERT INTO dbo.Module([ModuleName],[Description]) VALUES (@ModuleName,@Description)
        IF @@ERROR<>0    
        BEGIN
    ROLLBACK TRANSACTION        
        END
        
    COMMIT TRANSACTION

更新存储过程usp_Module_Update：

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE  PROCEDURE [dbo].[usp_Module_Update]
(
@ID tinyint,
@ModuleName nvarchar(50),
@Description nvarchar(50)
)
AS    
 SELECT [ModuleName] FROM [Module] WHERE [ModuleName]=@ModuleName AND [ModuleId]<>@ID
IF @@ROWCOUNT>0
BEGIN
RAISERROR(N'此模块已经存在，无法更新！',16,1)
RETURN
END
ELSE

  BEGIN TRANSACTION
            UPDATE [Module] SET [ModuleName]=@ModuleName,[Description]=@Description WHERE [ModuleId]=@ID
        IF @@ERROR<>0    
        BEGIN
            ROLLBACK TRANSACTION        
        END    
            COMMIT TRANSACTION
GO
