error select command denied to user useridip address for table table


error select command denied to user useridip address for table table  using -'mysql,mysqldatareader,mysql-error-1142'

In my website, I am using MySQL database. I am using a webservice where in I do all my database related manipulations.

Now In one of the methods of that webservice, I get the following Error.

select command denied to user ''@'' for table ''

What could be wrong?

Please Help and Suggest.

Thanks.

Below is the code where I get that error. I tried debugging and found that it fails at the line

MySqlDataReader result1 = command1.ExecuteReader();

        String addSQL = "Select Max(`TradeID`) from `jsontest`.`tbl_Positions";
        MySqlConnection objMyCon = new MySqlConnection(strProvider);
        objMyCon.Open();
        MySqlCommand command = objMyCon.CreateCommand();

        command.CommandText = addSQL;
         MySqlDataReader result = command.ExecuteReader();
        //int j = command.ExecuteNonQuery();
         while (result.Read())
         {
             MaxTradeID = Convert.ToInt32(result[0]);
         }
        objMyCon.Close();
        for (i = 1; i <= MaxTradeID; i++)
        {
            String newSQL = "Select `Strike`,`LongShort`,`Current`,`TPLevel`,`SLLevel` from `json`.`tbl_Position` where `TradeID` = '" + i + "'";
            MySqlConnection objMyCon1 = new MySqlConnection(strProvider);
            objMyCon1.Open();
            MySqlCommand command1 = objMyCon1.CreateCommand();

            command1.CommandText = newSQL;
            MySqlDataReader result1 = command1.ExecuteReader();
           objMyCon2.Close();
