How to delete row in go-sqlite3

I'm using below code for adding two rows in table

package main

import (
	"database/sql"
	"fmt"
	"log"
	"strconv"

	_ "github.com/mattn/go-sqlite3"
)

func main() {
	database, _ := sql.Open("sqlite3", "./nraboy.db")
	statement, _ := database.Prepare("CREATE TABLE IF NOT EXISTS people (id INTEGER PRIMARY KEY, firstname TEXT, lastname TEXT)")
	statement.Exec()
	statement, _ = database.Prepare("INSERT INTO people (firstname, lastname) VALUES (?, ?)")
	statement.Exec("Nic", "Raboy")
	statement, _ = database.Prepare("INSERT INTO people (firstname, lastname) VALUES (?, ?)")
	statement.Exec("Tom", "Hardy")
	_, err := statement.Exec("delete from people where id = 1")
	if err != nil {
		log.Fatal(err)
	}
	rows, _ := database.Query("SELECT id, firstname, lastname FROM people")
	var id int
	var firstname string
	var lastname string
	for rows.Next() {
		rows.Scan(&id, &firstname, &lastname)
		fmt.Println(strconv.Itoa(id) + ": " + firstname + " " + lastname)
	}
}

but when I'm adding _, err := statement.Exec("delete from people where id = 1") for removing one of row I get following error:

2021/07/09 16:21:07 sql: expected 2 arguments, got 1
exit status 1

How to delete row in table ?

It looks like you forgot to call statement, _ = database.Prepare("delete from people where id = 1") for the delete command. When you are calling statement.Exec("delete from people where id = 1") the statement that was previously prepared is still in effect, and it expects two arguments (firstname, lastname).
