#Node.jsからMySqlへのデータの更新

※自分用の覚え書きでございます。

req を受け取り、MySql へ post します。

###INSERT

app.js

app.post('/entry', (req, res) => {
  connection.query(
    'INSERT INTO tbl_items (name) VALUES (?)',
    [req.body.itemName],
    (error, results) => {
      connection.query(
        'SELECT * FROM tbl_items',
        (error, results) => {
          res.render('index.ejs', {items: results});
        }
      );
    }
  );
});

###UPDATE

app.js

app.post('/update/:id', (req, res) => {
  connection.query(
    'UPDATE tbl_items SET name = ? WHERE id = ?',
    [req.body.itemName,req.params.id],
    (error, results) => {
      res.redirect('/index');
    }
  );
});

###DELETE

app.js

app.post('/delete/:id', (req, res) => {
  connection.query(
    'DELETE FROM tbl_items WHERE id = ?',
    [req.params.id],
    (error, results) => {
      res.redirect('/index');
    }
  );
});
