using sql querys with an express app code example

Example 1: mssql query node js

const sql = require('mssql')
const query=`select * from table`;
config = {
    database: "dbname",
  // can keep these option required with latest version of mssql npm package
    options: {
      enableArithAbort: true,
      encrypt: true,
      rowCollectionOnRequestCompletion: false,
    },
    parseJSON: true,
    password: "password",
    port: port, // if youe database running on difrent port then 1433
    server: "server ip or name",
    user: "usenme",
  };

 
sql.on('error', err => {
    // ... error handler
})
 
sql.connect(config).then(pool => {
    return pool.request()
        .query(query)
}).then(result => {
    console.log(result.recordset)
}).catch(err => {
    console.log(err)
});

Example 2: how to access a database in express

var mysql = require('mysql')
var connection = mysql.createConnection({
  host: 'localhost',
  user: 'dbuser',
  password: 's3kreee7',
  database: 'my_db'
})

connection.connect()

connection.query('SELECT 1 + 1 AS solution', function (err, rows, fields) {
  if (err) throw err

  console.log('The solution is: ', rows[0].solution)
})

connection.end()
