Receive data from multiple tables [Nodejs,MySQL] - mysql

Question

What do I need to do to get data from multiple tables?
var express = require('express');
var app = express();
var mysql = require('mysql');
var connection = mysql.createConnection({
host : '',
user : '',
password : '',
database : ''
});
connection.connect(function(){
console.log("MySQL Database is Connected");
});
app.use(express.static(__dirname + '/css'));
app.use(express.static(__dirname + '/js'));
app.set('views', __dirname + '/views');
app.engine('html', require('ejs').renderFile);
app.get('/',function(req,res){
res.render('index.html');
});
app.get('/load',function(req,res){
connection.query("select * from terms WHERE status = 1",
function(err,rows,fields){
if(err) throw err;
res.end(JSON.stringify(rows));
});
});
app.listen(7001,function(){
console.log("App is started at PORT 7001");
});
With this I can only get data from the terms table. But I need to get data from the impTerms table.
How do I get this?
Thank you

Answer 1

Use sql join in query , has nothing to do with node js.
con.connect(function(err) {
if (err) throw err;
var sql = "SELECT terms.id, terms.name FROM terms JOIN impTerms ON impTerms.id= terms.id and terms.status=1";
con.query(sql, function (err, result) {
if (err) throw err;
console.log(result);
});
});

There are several ways you can do,
Passing two sql queries to connection
Var sqlQuery = "select * from terms WHERE status = 1;select * from impTerms";
connection.query(sqlQuery,
function(err,rows,fields){
if(err) throw err;
res.end(JSON.stringify(rows));
});
Output:
[
[], // array of object for terms
[] // array of object for impTerms
]
Changing select query
Var sqlQuery = "select a.*, b.* from a.terms, b.impTerms";
connection.query(sqlQuery,
function(err,rows,fields){
if(err) throw err;
res.end(JSON.stringify(rows));
});
