I want to display data of a student in an ejs page using the key value entered in the login js page. The query is getting displayed in git bash but nothing is being displayed in the ejs page.
rbulogin.js👇
var express = require("express");
var bodyparser = require("body-parser");
var request = require("request");
var createError = require('http-errors');
var db=require('./dbms');
const app = express();
app.set("view engine","ejs")
app.use(bodyparser.urlencoded({extended:true}));
app.use(express.static("public"));
let nwfname="";
let nwlname="";
let nwemail="";
let nwmob="";
app.get("/",function(req, res){
res.sendFile(__dirname+'/rbu_reg_form.html')
})
app.post("/", function(req, res){
var mreg = req.body.regno;
var msuin = req.body.suin;
res.locals.nwreg=mreg;
res.locals.nwsuin=msuin;
var sql = `SELECT * FROM rba1dr18 WHERE REG_NO="${mreg}" AND EXCL_ROLL="${msuin}"`;
db.query(sql, function(err, result) {
console.log("SQL run successfully...")
console.log(result);
res.render('rbu_form_save', {title: 'My Query Data', data: result});
});
});
app.post("/rbu_form_save", function(req, res){
res.redirect("/");
});
app.use(function(req, res, next) {
next(createError(404));
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
});
app.listen(3000, function(){
console.log("Server is Connected");
})

dbms.js
var mysql = require('mysql');
var conn = mysql.createConnection({
host: 'localhost', // Replace with your host name
user: 'root', // Replace with your database username
password: '', // Replace with your database password
database: 'anin' // // Replace with your database Name
});
conn.connect(function(err) {
if (err) throw err;
console.log('Database is connected successfully !');
});
module.exports = conn;
The above image is a portion of the table. I want to display the data of that student only according to the key fields ‘REG_NO’ and ‘EXCL_ROLL’
I want to the display the data of that student in this format:
Registration Number(‘REG_NO’): XXXXXXX
Name: XXXXXX
Student ID(‘EXCL_ROLL’): XXXXX
