Can Not Retrieve Nodejs MySQl Data From Database via sub function call












0















I have two files named login.js and dbMySql.js.



login.js is the main file that will run dbMySql.js, which is a submodule for the DB connection.



I can run getQuery() from dbMySql.js by using object.method call.



getQuery() also works fine and retrieves data from the database.



How can I get this data to my Main module from the database module? How can I return res variable to main function in login.js module



Code For login.js:



var MySqlConnect = require('./dbMySql');

var app = express();
var dbConnect = MySqlConnect("localhost", "root", "root", "mydb");

dbConnect.getQuery("select * from `test`");
console.log(dbConnect.resD);


Code For dbMySql.js:



function MySqlConnect(dbhost, dbuser, dbpassword, dbname) {
var MySqlConnect = require('mysql');
var con;
this.dbhost = dbhost;
this.dbuser = dbuser;
this.dbpassword = dbpassword;
this.dbname = dbname;
this.resultData = 'Def';
con = MySqlConnect.createConnection({
host: dbhost,
user: dbuser,
password: dbpassword,
database: dbname
})
con.connect(function (err) {
if (err) throw err;
})

function getQuery(query1) {
con.query(query1, function (err, res) {
if (err) throw err;

})
return {


resD: res

};

}

return {

getQuery: getQuery,

};


};

module.exports = MySqlConnect;


I want Retrieved Data in Main module via return method or any that will run successfully.
