I followed a tutorial to send query results obtained from pg to response.json in node.js and express.js . code given below

const getUsers = (request, response) => {
  pool.query('SELECT * FROM users ORDER BY id ASC', (error, results) => {
    if (error) {
      throw error
    }
    response.status(200).json(results.rows)
  })
}

but I am not to find any tutorial to send multiple query results something like below.

const getUsers = (request, response) => {
  pool.query('SELECT * FROM users ORDER BY id ASC', (error, results1) => {
    if (error) {
      throw error
    })
  }).then(  pool.query('SELECT * FROM provider ORDER BY id ASC', (error, results2) => {
    if (error) {
      throw error
    }
    response.status(200).json({"query1":results1.rows, "query2":results2.rows} )
  }
})
