【问题描述】：

我尝试连接到 oracle 11g 但我遇到问题并收到以下错误。错误表明我的 sql 语法一定有问题，但我在 oracle sql developer 中运行它。查询是正确的请帮我解决这个问题
谢谢。

 try {
                string oradb = "Data Source=(DESCRIPTION="
             + "(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xxx-PC)(PORT=1521)))"
             + "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=orcl)));"
             + "User Id=xxxx;Password=123456;";

                OracleConnection con = new OracleConnection();
                con.ConnectionString = oradb;

                //String command = "Select Object_name,status from object_name where object_type='" + object_typeCB.SelectedText + "'";


                string command = "select column1,column2,column3 from table1;";

                OracleDataAdapter oda = new OracleDataAdapter();

                oda.SelectCommand = new OracleCommand();
                oda.SelectCommand.Connection = con;
                oda.SelectCommand.CommandText = command;
                con.Open();
                oda.SelectCommand.ExecuteNonQuery();
                DataSet ds = new DataSet();
                oda.Fill(ds);
                dataGridView1.DataSource = ds;
                con.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message.ToString()+Environment.NewLine+ ex.StackTrace.ToString());
            }

错误：

ORA-00911: invalid character
