What I have tried:

                command.Connection = connection;
                command.CommandText = @"INSERT INTO Total ([Column1], [Column2], [Column3], [Date], [Receipt No], [Delivery Person], [Report], [Flavours], [Return])
VALUES (@Column1, @Column2, @Column3, @Date, @ReceiptNo, @DeliveryPerson, @Report, @Flavours, @Return)";
                connection.Open();
                 for (int j = 0; j < dataGridView1.Rows.Count ; j++)
    {
        var row = dataGridView1.Rows[j];
        if (row.IsNewRow) continue;
        command.Parameters.Clear();
        command.Parameters.AddWithValue("@Column1", row.Cells[0].Value);
        command.Parameters.AddWithValue("@Column2", row.Cells[1].Value);
        command.Parameters.AddWithValue("@Column3", row.Cells[2].Value);
        command.Parameters.AddWithValue("@Date", row.Cells[4].Value);
        command.Parameters.AddWithValue("@ReceiptNo", label2.Text);
        command.Parameters.AddWithValue("@DeliveryPerson", "---");
        command.Parameters.AddWithValue("@Report", row.Cells[0].Value);
        command.Parameters.AddWithValue("@Flavours", row.Cells[3].Value);
        command.Parameters.AddWithValue("@Return", textBox66.Text);
        command.ExecuteNonQuery();
    } connection.Close();
                    MessageBox.Show("Inserted Sucessfully", "Database", MessageBoxButtons.OK, MessageBoxIcon.Information);
