不能使用C＃在oracle數據庫中插入記錄

Question

try 
{ 
    int val4 = Convert.ToInt32(tbGrupa.Text); 
    string MyConString = "Data Source=**;User ID=******;Password=*****"; 
    OracleConnection conexiune = new OracleConnection(MyConString); 
    OracleCommand comanda = new OracleCommand(); 
    comanda.Connection = conexiune; 
    conexiune.Open(); 
    comanda.Transaction = conexiune.BeginTransaction(); 
    int id_stud = Convert.ToInt16(tbCodStud.Text); 
    string nume = tbNume.Text; 
    string prenume = tbPrenume.Text; 
    string initiala_tatalui = tbInitiala.Text; 
    string email = tbEmail.Text; 
    string facultate = tbFac.Text; 
    int grupa = Convert.ToInt16(tbGrupa.Text); 
    string serie = tbSeria.Text; 
    string forma_de_inv = tbFormaInvatamant.Text; 
    DateTime data_acceptare_coordonare = dateTimePicker1.Value; 
    DateTime data_sustinere_licenta = dateTimePicker2.Value; 
    string sustinere = tbSustinereLicenta.Text; 
    string parola_acces = tbParola.Text; 

    try 
    { 
     comanda.Parameters.AddWithValue("id_stud", id_stud); 
     comanda.Parameters.AddWithValue("nume", nume); 
     comanda.Parameters.AddWithValue("prenume", prenume); 
     comanda.Parameters.AddWithValue("initiala_tatalui", initiala_tatalui); 
     comanda.Parameters.AddWithValue("facultate", facultate); 
     comanda.Parameters.AddWithValue("email", email);

     comanda.Parameters.AddWithValue("parola_acces", parola_acces); 

     comanda.Transaction.Commit(); 
     MessageBox.Show("Studentul " + tbNume.Text + " " + tbPrenume.Text + " a fost adăugat în baza de date!"); 
    } 
    catch (Exception er) 
    { 
     comanda.Transaction.Rollback(); 
     MessageBox.Show("ER1.1:" + er.Message); 
     MessageBox.Show("ER1.2:" + er.StackTrace); 
    } 
    finally 
    { 
     conexiune.Close(); 
    } 
} 
catch (Exception ex) 
{ 
    MessageBox.Show("ER2.1:"+ex.Message); 
    MessageBox.Show("ER2.2:"+ex.StackTrace); 
}

似乎沒有插入語句。我認爲這是問題所在。你需要一些東西，如：

using (OracleConnection connection = new OracleConnection(connectionString)) 
{ 
    OracleCommand command = new OracleCommand(myExecuteQuery, connection); 
    command.Connection.Open(); 
    command.ExecuteNonQuery(); 
} 

有一個提交語句，如果之前沒有插入語句，你會提交什麼？
