)

func main() {
	db, err := sql.Open("sqlite3", "./foo.db")
	if err != nil {
		log.Fatalf("failed connect database: %s", err)
	}

	q := NewPersonSQL().Select().ID(uint64(1))
	query, args, err := q.ToSql()
	if err != nil {
		log.Fatalf("query build error: %s", err)
	}

	row := db.QueryRow(query, args...)
	var id uint64
	var firstName, lastName string
	err = row.Scan(&id, &firstName, &lastName)
	if err != nil {
		log.Fatalf("query exec error: %s", err)
	}
	log.Printf("id=%d, first_name=%s, last_name=%s", id, firstName, lastName)
