Stored procedure error: int is incompatible with uniqueidentifier

Question

我正在尝试解决客户站点上的登录问题。我的公司没有建立网站，但我们只是在客户需要时进行更新。我尝试在浏览器中登录时遇到的错误是：

"Operand type clash: int is incompatible with uniqueidentifier"

堆栈跟踪和代码片段如下。我希望我在下面包含的内容足够详尽，因为我很难弄清楚我在这里遗漏了什么。我不是 .NET 开发人员，所以这不是我经常使用的东西。

这是堆栈跟踪：

这是tmsCommon.Authenticate代码：

Public Function Authenticate(ps_login As String, ps_password As String) As Object
    Dim sqlConnection As SqlConnection = New SqlConnection(Conversions.ToString(RuntimeHelpers.GetObjectValue(Me.GetConnString())))
    sqlConnection.Open()
    Dim sqlCommand As SqlCommand = New SqlCommand("sp_Authenticate", sqlConnection)
    Dim num As Integer = 0
    sqlCommand.CommandType = CommandType.StoredProcedure
    sqlCommand.Parameters.Add("@username", SqlDbType.VarChar, 255).Value = ps_login
    sqlCommand.Parameters.Add("@password", SqlDbType.VarChar, 255).Value = ps_password
    Dim sqlDataReader As SqlDataReader = sqlCommand.ExecuteReader()
    If sqlDataReader.Read() Then
        num = Conversions.ToInteger(RuntimeHelpers.GetObjectValue(sqlDataReader("auth")))
    End If
    sqlConnection.Close()
    Return num
End Function

这是从 tmsCommon.Authenticate:

调用的存储过程 sp_authenticate

            if (@isapproved=0) and (datediff(dd,@appdate,getdate())>31) 
            begin
                select @result=2 
            end
            if (@isapproved=2)
            begin
                select @result=3
            end
            if (@islockedout=1)
            begin
                select @result=4
            end



    end

    select @result as Auth
END

这是在 sp_authenticate:

中调用的存储过程 spGetUserIDByName

        SELECT TOP 1 @UserId = u.UserId
        FROM    dbo.aspnet_Applications a, dbo.aspnet_Users u, dbo.aspnet_Membership m
        WHERE    LOWER('/') = a.LoweredApplicationName AND
                u.ApplicationId = a.ApplicationId    AND
                LOWER(@UserName) = u.LoweredUserName AND u.UserId = m.UserId

END

sp_authenticate 在 SQL Server Management Studio 中执行：

USE [tmstradedb]
GO

DECLARE @return_value int

EXEC    @return_value = [dbo].[sp_authenticate]
        @UserName = N'123-456', --fake user name
        @password = N'2345' -- fake password

SELECT  'Return Value' = @return_value

GO

执行返回错误：消息 206，级别 16，状态 2，过程 dbo.spGetUserIDByName，第 0 行 [批处理起始行 2] 操作数类型冲突：int 与 uniqueidentifier

不兼容

******更新***** 我根据收到的反馈尝试了一些事情。我将 spGetUserIDByName 过程修改为以下内容：

USE [tmstradedb]
GO
/****** Object:  StoredProcedure [dbo].[spGetUserIDByName]    Script Date: 7/27/2018 2:12:18 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
--select dbo.[spGetUserIDByName]('neal')
ALTER PROCEDURE [dbo].[spGetUserIDByName]
    @UserName             nvarchar(256),
    @UserId uniqueidentifier OUTPUT
AS
BEGIN
        --DECLARE @UserId uniqueidentifier

         -- select user ID from aspnet_users table
        SELECT TOP 1 @UserId = u.UserId
        FROM    dbo.aspnet_Applications a, dbo.aspnet_Users u, dbo.aspnet_Membership m
        WHERE    LOWER('/') = a.LoweredApplicationName AND
                u.ApplicationId = a.ApplicationId    AND
                LOWER(@UserName) = u.LoweredUserName AND u.UserId = m.UserId

    RETURN;

END

我也对 sp_authenticate 程序进行了更改：

USE [tmstradedb]
GO
/****** Object:  StoredProcedure [dbo].[sp_authenticate]    Script Date: 7/27/2018 2:13:12 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- sp_authenticate 'neal','blue96'
ALTER PROCEDURE [dbo].[sp_authenticate]
    ( @UserName             varchar(255),
    @password       varchar(255))
AS
BEGIN
    DECLARE @UserId uniqueidentifier
    declare @result int
    set @result=0

    declare @appdate datetime
    declare @guestmember int
    Declare @isapproved int
    declare @islockedout int
    --EXEC @UserId = dbo.spGetUserIDByName @UserName
    EXEC dbo.spGetUserIDByName @UserName



        SELECT @result=1,@guestmember=guestmember,@appdate=approveddate,@islockedout=islockedout,@isapproved=isapproved 
        FROM    dbo.aspnet_Membership m 
        WHERE  m.password=@password and m.userid=@UserId and deleted=0 and archived=0 


        IF (@result >0) -- Username  found

        begin



            UPDATE   dbo.aspnet_Users SET LastActivityDate = getdate() WHERE    @UserId = UserId
            if (@isapproved=0) and (datediff(dd,@appdate,getdate())>31) 
            begin
                select @result=2 
            end
            if (@isapproved=2)
            begin
                select @result=3
            end
            if (@islockedout=1)
            begin
                select @result=4
            end



    end

    select @result as Auth
END

我知道我还是做错了，因为当我像上面的例子一样执行 sp_authenticate 时，我现在得到这个错误：

消息 201，级别 16，状态 4，过程 dbo.spGetUserIDByName，第 0 行 [批处理开始第 2 行] 过程或函数 'spGetUserIDByName' 需要未提供的参数“@UserId”。

Answer 1

这是问题所在：

EXEC @UserId = dbo.spGetUserIDByName @UserName

在被调用的存储过程中，您声明并填充了一个 GUID 变量：

 DECLARE @UserId uniqueidentifier

         -- select user ID from aspnet_users table
        SELECT TOP 1 @UserId = u.UserId
        FROM   ...

但是您永远不会将该变量用作存储过程的输出。

在该过程的末尾添加这个可能会解决问题：

RETURN @UserID;

一个更规范的修复方法是将 @UserID 变成一个 OUTPUT 参数并在调用过程中相应地捕获它。

Answer 2

sp_getuseridbyname returns "key" 通过输出参数。您没有正确调用该过程。您必须 "pass" 一个 UID 变量作为参数才能访问该过程设置的值。

exec dbo.spGetUserIDByName @UserName, @UserID OUTPUT;

您在身份验证过程中声明了变量但没有使用它们。专注于您的代码。停止添加更多的东西，尝试一些东西，让自己感到困惑。
