[RESOLVED] [2.0] ASP.net using C# and MySQL

I can't figure it out why this code only adds new row but can't save the information in the mysql database.

Code:

---

private void AddParam(MySqlCommand cmd, params string[] cols)
    {
        foreach (string col in cols)
        {
            cmd.Parameters.Add("@" + col, MySqlDbType.Text, 0, col);
        }
    }

---

Code:

---

    public int currRec = 0;

---

Code:

---


    protected void saveButton_Click(object sender, EventArgs e)
    {
        MySqlConnection conn = new MySqlConnection("Data Source=localhost; Database=DB; user id=userdb; password=pass; persist security info=true;");
        string sql = "select * from tblUserAccount";
        MySqlDataAdapter da = new MySqlDataAdapter(sql, conn);

        DataSet ds = new DataSet();

        da.Fill(ds, "tblUserAccount");
        DataRow dr = ds.Tables[0].NewRow();
        ds.Tables[0].Rows.Add(dr);

        da.InsertCommand = conn.CreateCommand();
        da.InsertCommand.CommandText = "Insert Into tblUserAccount (fname, lname, usernames, passwords, AccountType, priv) " +
            "Values (@fname, @lname, @usernames, @passwords, @accounttype, @priv)";
        AddParam(da.InsertCommand, "fname", "lname", "usernames", "passwords", "accounttype", "priv");
       
        dr.BeginEdit();
        dr["fname"] = txtFname.Text;
        dr["lname"] = txtLname.Text;
        dr["usernames"] = txtUsername.Text;
        dr["passwords"] = txtPassword1.Text;
        dr["accounttype"] = cboAccountType.Text;
        dr["priv"] = cboPriv.Text;
        dr.EndEdit();

       

        da.Update(ds, "tblUserAccount");
        ds.AcceptChanges();

        conn.Close();
        conn.Dispose();

    }

Because you have not specified an UpdateCommand for your DataAdapter.

Instead of doing this:

Code:

---

private void AddParam(MySqlCommand cmd, params string[] cols)
    {
        foreach (string col in cols)
        {
            cmd.Parameters.Add("@" + col, MySqlDbType.Text, 0, col);
        }
    }

---

Code:

---

da.InsertCommand.CommandText = "Insert Into tblUserAccount (fname, lname, usernames, passwords, AccountType, priv) " +
            "Values (@fname, @lname, @usernames, @passwords, @accounttype, @priv)";
        AddParam(da.InsertCommand, "fname", "lname", "usernames", "passwords", "accounttype", "priv");

---

I tried to change it to:

Code:

---

private void AddParam(MySqlCommand cmd, params string[] cols)
    {
        foreach (string col in cols)
        {
            cmd.Parameters.Add("?" + col, MySqlDbType.Text, 0, col);
        }
    }

---

Code:

---

da.InsertCommand.CommandText = "Insert Into tblUserAccount (fname, lname, usernames, passwords, AccountType, priv) " +
            "Values (?fname, ?lname, ?usernames, ?passwords, ?accounttype, ?priv)";
        AddParam(da.InsertCommand, "fname", "lname", "usernames", "passwords", "accounttype", "priv");
