问题描述

请提出一些感谢提前



我的尝试：

Im trying to assign the data from the oracle data base to the data grid view in a windows application bt it is not working it is not assigning the data to data table
please suggest something thanks in advance

What I have tried:

string ConnStr = GetConnectionString_Oracle();

               // string ConnStr = ConfigurationManager.ConnectionStrings["ConStr"].ConnectionString;
               using (OracleConnection connection = new OracleConnection())
               {
                   connection.ConnectionString = ConnStr;
                   connection.Open();
                   Console.WriteLine("State: {0}", connection.State);
                   Console.WriteLine("ConnectionString: {0}",
                                     connection.ConnectionString);

                   OracleCommand command = connection.CreateCommand();

                   string sql = "select * from LCLDocMst where LossType  ='" + lblLossType.Text.TrimStart() + "'";
                   command.CommandText = sql;

                   OracleDataReader reader = command.ExecuteReader();
                   DataTable dataTable = new DataTable();
                   dataTable.Load(reader);
                   gvDetails.DataSource = dataTable;

                   //while (reader.Read())
                   //{
                   //      myField = reader.GetInt32(0);

                   //}

               }

推荐答案

command.CommandType = CommandType.Text;

。在您的代码中的command.CommandText = sql旁边;

. next to command.CommandText=sql in your code;
