请教：为什么存储过程不执行？

存储过程是这么写的

CREATE PROCEDURE UpLoadFromBank

@b_num varchar(20),
@money decimal,
@ssfd varchar(20),
@time datetime
AS
update db_student set s_ssf=@money,s_ssfd=@ssfd,s_dayinup='1',s_qf='0' where 

s_num=@b_num
update db_ruzhu set ruzhu_ynjf='已交',ruzhu_nfjf='否',ruzhu_jftime=@time where 

ruzhu_num=@b_num
insert into db_cruzhu

(cruzhu_num,cruzhu_area,cruzhu_nj,cruzhu_zsf,cruzhu_time,cruzhu_lou,cruzhu_leibie) 

select ruzhu_num,ruzhu_area,ruzhu_nianji,ruzhu_zsf,convert(varchar(10),getdate

(),120),ruzhu_gongyu,ruzhu_leibie from db_ruzhu where ruzhu_num=@b_num

GO

。Net中是这么写的

DataTable tablefuckT=(DataTable)Session["tableFuckT"];

            SqlConnection conn = operate_sql.createCon();
            conn.Open();
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = conn;
            
            
            int a=0;
            foreach(DataRow dr in tablefuckT.Rows)
            {
                a = a+1;
                
                string b_num=dr["b_number"].ToString();
                decimal money = Convert.ToDecimal(dr["b_money"]);
                Center.Help.Help.Money Mssf = new HbuHouse.Center.Help.Help.Money(money);
                string ssfd = Mssf.ToString();
                if(b_num!="")
                {

                    cmd.CommandText = "UpLoadFromBank";
                    cmd.CommandType = CommandType.StoredProcedure;

                    cmd.Parameters.Add("@b_num",SqlDbType.VarChar,20);
                    cmd.Parameters["@b_num"].Value = "1";
                    cmd.Parameters.Add("@money",SqlDbType.Decimal);
                    cmd.Parameters["@money"].Value = money;
                    cmd.Parameters.Add("@ssfd",SqlDbType.VarChar,20);
                    cmd.Parameters["@ssfd"].Value = ssfd;
                    cmd.Parameters.Add("@time",SqlDbType.DateTime);
                    cmd.Parameters["@time"].Value = operate_admin.GetSystemDate().ToString();

                    cmd.ExecuteNonQuery();
                    cmd.Parameters.Clear();
                }

                
                
                
            }
            conn.Close();
            conn.Dispose();

请帮忙看看是哪里的问题？
