即使我在 ASP 中发送值也没有运行查询

Question

我正在运行一个更新查询，它说它没有找到第二个参数（状态），尽管我很清楚地发送了它。它们在不同的类中，被一个按钮调用，该按钮发送一封邮件，然后更改主表中变量 (statusRef) 的值（此字段是新字段）。

    protected void sendMail(object sender, EventArgs e)
    {
        BO.Messages mail = new BO.Messages();
        string body = "Cuerpo Mensaje";
        string title = "Titulo";
        string script = "alert(\"An email has been sent to the candidate! \");";
        mail.refEmail(emailCandi.Text,title,body);
        ScriptManager.RegisterStartupScript(this, GetType(),
                              "ServerControlScript", script, true);
        Email_Sent.Visible = true;
        changeRefStatus(Int32.Parse(idCand.Text), "1");           
    }

    protected void changeRefStatus(int id, string status)
    {
        ASF.HC.JobApplication.BO.User u = new ASF.HC.JobApplication.BO.User();
        u.saveStatusRef(id,status);


    }

    public int saveStatusRef(int id, string status)
    {
        Entity.User u = new Entity.User();
        SqlCommand comando = new SqlCommand("dbo.[user_saveStatusRef]", base.Db);
        SqlParameter spSearch = new SqlParameter("@id", System.Data.SqlDbType.Int);
        SqlParameter spSearch2 = new SqlParameter("@status", System.Data.SqlDbType.VarChar);
        spSearch.Value = id;
        spSearch.Value = status;
        comando.Parameters.Add(spSearch);
        comando.Parameters.Add(spSearch2);
        return base.ExecuteScalar(comando);
    }

存储过程...

ALTER PROCEDURE dbo.user_saveStatusRef 
@id int,
@status varchar(5)
AS
UPDATE tbl_user
set statusRef = @status
WHERE id = @id

Answer 1

可能是一个错字，但您没有将值分配给spSearch2

    spSearch.Value = id;
    spSearch.Value = status;
