关于在asp中用存储过程操作数据库遇到的有关问题，很急

关于在asp中用存储过程操作数据库遇到的问题，很急！！！
先说一个没有问题的，是更新数据的，存储过程为

SQL code

ALTER PROCEDURE insert_customer
(
@customid [char] (10),
@customname [char] (10),
@customcharge [char] (10),
@customdesc [varchar] (100),
@customlevel [int]
)
AS
insert into [corporation].[dbo].[customer]
(
[CustomID],
[CustomName],
[CustomCharge],
[CustomDesc],
[CustomLevel]
)
values
(
@customid,
@customname,
@customcharge,
@customdesc,
@customlevel
)
RETURN

asp中的代码就不贴了，
再看下出错的，很不解：

SQL code

ALTER PROCEDURE update_customer
(
@customid [char] (10),
@oldcustomid [char] (10),
@customname [char] (10),
@customcharge [char] (10),
@customdesc [varchar] (100),
@customlevel [int]
)
AS
update [corporation].[dbo].[customer]

set
[CustomID] = @customid,
[CustomName] = @customname,
[CustomCharge] = @customcharge,
[CustomDesc] = @customdesc,
[CustomLevel] = @customlevel
where
(CustomID = @oldcustomid)
RETURN

报错说[corporation].[dbo].[customer]对象名无效，为什么？，上面的更新的都没错，插入数据就有错了！
asp中的代码如下：

C# code

 string strconn = Convert.ToString(ConfigurationManager.ConnectionStrings["ConnectionString"]);
  SqlConnection conn = new SqlConnection(strconn);

  conn.Open();
  SqlCommand cmd = new SqlCommand("insert_customer", conn);
  cmd.CommandType = CommandType.StoredProcedure;
  cmd.Parameters.Add(new SqlParameter("@customid", TextBox1.Text.Trim()));
  cmd.Parameters.Add(new SqlParameter("@customname", TextBox2.Text.Trim()));
  cmd.Parameters.Add(new SqlParameter("@customcharge", DropDownList1.Text.Trim()));
  cmd.Parameters.Add(new SqlParameter("@customdesc", TextBox3.Text.Trim()));
  cmd.Parameters.Add(new SqlParameter("@customlevel", DropDownList2.Text.Trim()));
  cmd.ExecuteNonQuery();
  Response.Redirect("Customers.aspx");

  conn.Close();

明天就得交了，求大虾给解释下，初学asp，头快爆了！！！

------解决方案--------------------
你不会同时在进行更新和插入操作吧？

语句是没有什么问题的
