package main

import "fmt"

// DataSource contohnya "koneksi" ke DB tertentu
type DataSource struct {

$ sudo apt install default-mysql-server default-mysql-client

$ sudo cat /etc/mysql/debian.cnf

[client]
host     = localhost
user     = debian-sys-maint
password = JRptVM1k9l8SvIau
socket = /var/run/mysqld/mysqld.sock

$ sudo cat /etc/mysql/debian.cnf

host = localhost

	# create script

	var op = e.parameter.action;
	var ss = SpreadsheetApp.open(DriveApp.getFileById("YOUR_SPREADSHEET_ID"));
	var sn = "YOUR_SHEET_NAME";
	var sheet = ss.getSheetByName(sn);
