MySql stored procedure not exist with C# .NET

Question

I try connected MySql stored procedure from c# .Net via MySqlDataAdapter but when i fill data to datatable or dataset has error "Additional information: FUNCTION demo.loadtable does not exist".

My stored

DELIMITER $$
USE `demo`$$
DROP PROCEDURE IF EXISTS `loadtable`$$
CREATE DEFINER=`root`@`localhost` PROCEDURE `loadtable`()
BEGIN
        SELECT * FROM tablesx;
    END$$
 DELIMITER ;

 My code

1. loadData method

public void loadData(tables model)
       {
           connect();
           ds= new DataSet();
           MySqlParameter[] prams = {
                               MakeInParam("@id",MySqlDbType.Int32,4,model.id)
                           };
           RunProcDS("loadtable", prams, out ds);
         }

 2. RunProcDS method

public int RunProcDS(string procName, MySqlParameter[] prams, out DataSet dataSet)
        {
            DataSet ds;
            MySqlCommand cmd = CreateCommand(procName, prams);
            MySqlDataAdapter dad = new MySqlDataAdapter(cmd);
            MySqlCommandBuilder cb = new MySqlCommandBuilder(dad);
            ds = new DataSet();
            dad.Fill(ds, "CurrentItems");
            dataSet = ds;
            this.Close();
            return (int)cmd.Parameters["ReturnValue"].Value;
        }

 Has error att line 08 " dad.Fill(ds, "CurrentItems"); "

 3. CreateCommand method

private MySqlCommand CreateCommand(string procName, MySqlParameter[] prams)
        {
            Open();
            MySqlCommand cmd = new MySqlCommand(procName, con);
            if (cmd.Parameters.Count > 0)
            {
                cmd.Parameters.Clear();
            }
            cmd.CommandType = CommandType.StoredProcedure;
            if (prams != null)
            {
                foreach (MySqlParameter parameter in prams)
                    cmd.Parameters.Add(parameter);
            }
            cmd.Parameters.Add(
                new MySqlParameter("ReturnValue", MySqlDbType.Int32, 4,
                ParameterDirection.ReturnValue, false, 0, 0,
                string.Empty, DataRowVersion.Default, null));

            return cmd;
        }

 Please help.

 

Thanks,
