NodeJS: How do I assign a query result into a variable and use it to populate html table?
I have been doing NodeJS and Express practise since few days. I want to return a query result and assign it on a html table in NodeJS. Here's what I have done:
//My controller
exports.mainpage = function(req,res){
sql = "SELECT * from students";
var qry = db.query(sql,function (err, result) {
if (err) throw err;
return result;
});
console.log(qry);
res.render('layouts/main', qry);
}
Routes:
router.get('/', student_controller.mainpage);
HTML(using handlebars):
<table class="table">
<thead>
<tr>
<th>#</th>
<th>Name</th>
<th>Gender</th>
<th>DOB</th>
</tr>
</thead>
<tbody>
{{#each qry}}
<td>1</td>
<td>{{this.name}}</td>
<td>{{this.gender}}</td>
<td>{{this.dob}}</td>
{{/each}}
</tbody>
</table>
I am getting so many error. I guess my code are wrong. Please help me correct this code.

What errors are you receiving?
I'll respond to the most obvious problem not knowing all the errors you have:
The most obvious issue is you never define resultqry in your controller.
You assign the result of your db query to a variable called qry, but then you send an undefined and undeclared variable resultqry to your template.
Instead of var qry = use var resultqry=
var resultqry = db.query(sql,function (err, result) {
if (err) throw err;
return result;
});
console.log(resultqry);
res.render('layouts/main', resultqry);

My assumption is that you are not getting the results in your result object. That is because you need to wait for the results to be returned before you do a render. Try something like following:
exports.mainpage = function(req,res){
sql = "SELECT * from students";
db.query(sql)
.then(result => res.render('layouts/main', result);
.catch(error => console.log(error) //put your error handler here
