Question

I am trying to update my MySql database but it won’t work. I have inserting and selecting working fine. Not sure if it is my syntax on the query or what.

string id = invoicenumb.Text;
string mysqlIns1 = "UPDATE invoices SET Status = '" + 
                    comboBox1.SelectedItem.ToString() + "' WHERE id = '" +
                    Convert.ToInt16(id) + "'";


            try
            {
                MySqlConnection mysqlCon = new MySqlConnection(mysqlProv);
                mysqlCon.Open();

                MySqlDataAdapter MyDA = new MySqlDataAdapter();
                MyDA.SelectCommand = new MySqlCommand(mysqlIns1, mysqlCon);

                MessageBox.Show("Success!");
                mysqlCon.Close();
            }
            catch
            {
                MessageBox.Show("Error Occured Please Try Again");
            }

Use UpdateCommand instead of SelectCommand.

See MySqlDataAdapter.UpdateCommand Property
