Question

管理员即John在注册后链接到人力资源部门，然后选择人力资源部门，他的数据存储在用户表中，在此表中，id设置为dep id = 2，即dep2。

然后我想通过他的登录ID和密码登录然后他只能访问HR文档，而不是其他文档，如金融，计算机科学，市场营销，我已经尝试过这个查询。

首先我选择dep id：

ALTER procedure [dbo].[sphrdoc]
@UserName  nvarchar(50),
@Password nvarchar(50)
as
select DepID from Userss where UserName=@UserName AND [Password]=@Password

然后我创建一个函数：

publicint  hrdoc(string Username,string password)
    {
        return Convert.ToInt32( db.ExecuteScalar("sphrdoc",newobject[]  
       {Username,password}));

    }

然后在页面加载中：

Session["a"] = dd.hrdoc(Convert.ToString(Session["Login2"]),   
(Convert.ToString(Session["Login3"])));

然后我设置了这个查询：

ALTER procedure [dbo].[sphrdocid1]
 @DepID int
as
 SELECT DocumentInfo.DocID,
 dbo.DocumentInfo.DocName,
dbo.DocumentInfo.Uploadfile,
dbo.DocType.DocType,
 dbo.Department.DepType ,
dbo.ApproveType.ApproveType AS ApproveID
FROM dbo.DocumentInfo
left JOIN dbo.DocType ON dbo.DocumentInfo.DocTypeID=dbo.DocType.DocTypeID
left JOIN dbo.Department ON dbo.DocumentInfo.DepID=dbo.Department.DepID
LEFT JOIN dbo.ApproveType ON dbo.ApproveType.approveid=dbo.Department.DepID where   
dbo.Department.DepID=@DepID


public DataTable hrdoc1(int id)
    {           
        DataTable table = db.ExecuteDataSet("sphrdocid1", new object[] { id 
       }).Tables[0];
        return table;

    }

然后在页面加载中我称之为：

GrdFileApprove.DataSource = dd.hrdoc1(Convert.ToInt32(Session["a"]));
          GrdFileApprove.DataBind();

但是当约翰登录时，他仍可以看到与人力资源，市场营销，金融，计算机科学相关的所有文件。

您的查询看起来是正确的。您需要检查数据以确保正确填充所有值。

这是您使用的实际代码吗？你在Department表上需要左连接吗？

exec sphrdocid1 @DepID = 1

go
ALTER procedure [dbo].[sphrdocid1]
 @DepID int
as
begin
SELECT DocumentInfo.DocID, dbo.DocumentInfo.DocName, dbo.DocumentInfo.Uploadfile, dbo.DocType.DocType, dbo.Department.DepType , dbo.ApproveType.ApproveType AS ApproveID
FROM dbo.DocumentInfo
JOIN dbo.Department
    ON dbo.DocumentInfo.DepID=dbo.Department.DepID
left JOIN dbo.DocType 
    ON dbo.DocumentInfo.DocTypeID=dbo.DocType.DocTypeID
LEFT JOIN dbo.ApproveType 
    ON dbo.ApproveType.approveid=dbo.Department.DepID 
where  dbo.DocumentInfo.DepID=@DepID
end

管理员通过部门查看文档
