如何將數據插入SQL Server？

Question

我有這樣的代碼：

con.Open();

cmd = new SqlCommand("insert into Penawaran (ID_Paket,Jenis_Paket,Harga_Paket) Values (@ID_Paket,@Jenis_Paket,@Harga_Paket", con);

cmd.Parameters.AddWithValue("@ID_Paket", txtIDPaket.Text);
cmd.Parameters.AddWithValue("@Jenis_Paket", txtjenisPaket.Text);
cmd.Parameters.AddWithValue("@Harga_Paket", txtHargaPaket.Value); // this is int sir how to insert it, still error i write like this

cmd.ExecuteNonQuery();
con.Close();

請幫我把int Paket我的桌子Paket 。

Answer 1

Insert查詢末尾缺少括號

 INSERT INTO Penawaran (ID_Paket,Jenis_Paket,Harga_Paket)
               VALUES (@ID_Paket,@Jenis_Paket,@Harga_Paket) --Here

嘗試這個

           SqlConnection con = new SqlConnection();
            con.Open();
            SqlCommand cmd = new SqlCommand("insert into Penawaran (ID_Paket,Jenis_Paket,Harga_Paket) Values (@ID_Paket,@Jenis_Paket,@Harga_Paket", con));
            cmd.Parameters.Add("@ID_Paket", SqlDbType.Int);
            cmd.Parameters.Add("@Jenis_Paket", SqlDbType.VarChar);
            cmd.Parameters.Add("@Harga_Paket", SqlDbType.VarChar); // this is int sir how to insert it, still error i write like this

            cmd.Parameters["@ID_Paket"] = int.Parse(txtIDPaket.Text);
            cmd.Parameters["@Jenis_Paket"] = txtjenisPaket.Text;
            cmd.Parameters["@Harga_Paket"]  = txtHargaPaket.Value; // this is int sir how to insert it, still error i write like this
            cmd.ExecuteNonQuery();
            con.Close();
