目标：根据.aspx.vb代码中的传入值更改要更新的字段

问题：我相信上面的Aim有效，但我在PropertyID（字母数字）上收到错误，因为它说无效的列名＆＃39; S7753＆＃39; 我正在更新PropertyID S7753。

.aspx.vb代码：

command.CommandText = "spActionUpdateOldestDate"
        command.CommandType = CommandType.StoredProcedure

        Dim vCheck As String = Session.Item("PropertyID").ToString & "-" & Session.Item("SafeGuardingDate").ToString & "-" & Session.Item("ActionsFieldName").ToString

        command.Parameters.AddWithValue("@PropertyID", Session.Item("PropertyID").ToString)
        command.Parameters.AddWithValue("@SafeGuardingDate", Session.Item("SafeGuardingDate").ToString)
        command.Parameters.AddWithValue("@ActionsFieldName", Session.Item("ActionsFieldName").ToString)

        command.ExecuteNonQuery()

        command.Parameters.Clear()

存储过程

    USE [DB]

GO
/****** Object:  StoredProcedure [dbo].[spActionUpdateOldestDate]    Script Date: 04/02/2014 14:24:09 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[spActionUpdateOldestDate] 

-- spActionUpdateOldestDate '1234','date','field'
    -- Add the parameters for the stored procedure here
            @PropertyID nvarchar(50)            
            ,@SafeGuardingDate nvarchar(MAX) 
             ,@ActionsFieldName varchar(MAX)

AS
BEGIN

-- add selection for courseID etc.. here

-- print 'UPDATE [TblActionsOldest] SET ' + @ActionsFieldName + ' = ''' + @SafeGuardingDate + ''' WHERE PropertyID = ''' + @PropertyID+ ''''
Execute ('UPDATE [TblActionsOldest] SET ' + @ActionsFieldName + ' = ''' + @SafeGuardingDate + ''' WHERE PropertyID = ''' + @PropertyID+ '''')
