I am trying to select items from sql server but I am getting below error. My SELECT statement right after completion on INSERT statement. What should I do to select properly without this error? Should I create separation connection?

I am trying to store result data received from client side into sql database, however I am getting these errors
TypeError: request.query(...).then is not a function
TypeError: callback is not a function
I am quite new to node.js and sql database. I spent quite a bit of time to figure these but not sure where to start,,
I tried to remove .then, it works fine but still throws 2nd error. Can anyone please advice on this problem?

request.query("INSERT INTO RMS (GradeA, GradeB, GradeC) values VALUES ? ", [values]) should be the line giving the error. It assumes the second parameter should be function. And when the second parameter is passed it does not return a promise and thus does not have then method.
mssql modules does not seem to support escaping in the way you are trying to do it. It support input method which can be used to inject data into query. From docs:
request
.input('input_parameter', sql.Int, value)
.query('select * from mytable where id = #input_parameter'
I am new at here and I am getting Can not post /api/register error in postman and 404 not found in console, I have checked all the possible question answers. Please assist me as soon as possible.

When you use
app.use('/api/register', require('./controllers/auth.controller'));
Your application routes everything that comes to /api/register into require('./controllers/auth.controller'). Then require('./controllers/auth.controller') checks the remainder of the url for /api/register or /api/login, routes the request to the respective middleware if your router gets a match.
In other words, you need to post to /api/register/api/register in order to reach your desired middleware.
For a quick solution:
You should delete
app.use('/api/register', require('./controllers/auth.controller'));
app.use('/api/login', require('./controllers/auth.controller'));
and replace it with:
app.use('/', require('./controllers/auth.controller'));
For a better one:
You should delete
app.use('/api/register', require('./controllers/auth.controller'));
app.use('/api/login', require('./controllers/auth.controller'));
and replace it with:
app.use('/api', require('./controllers/auth.controller'));
in your app.js and also in your auth.controller.js you should replace:
route.post('/api/register', function (req, res) {
console.log(req.body);//res.sendStatus(200);
// userModel.create(req.body).then( function () {
// res.sendStatus(200);
// }).catch( function (err) {
// res.status(400).send(err);
// });
});
/**
*
* Login user
*/
route.post('/api/login', function (req, res) {
// userModel.authenticate(req.body.email, req.body.password).then( function () {
// res.sendStatus(200);
// }).catch( function (err) {
// res.status(400).send(err);
// });
});
with:
route.post('/register', function (req, res) {
console.log(req.body);//res.sendStatus(200);
// userModel.create(req.body).then( function () {
// res.sendStatus(200);
// }).catch( function (err) {
// res.status(400).send(err);
// });
});
/**
*
* Login user
*/
route.post('/login', function (req, res) {
// userModel.authenticate(req.body.email, req.body.password).then( function () {
// res.sendStatus(200);
// }).catch( function (err) {
// res.status(400).send(err);
// });
});
I am using angular2 and mssql to connect to SQL Server.
This is my code
var express = require('express');
var app = express();
var sql = require("mssql");
// config for your database
var config = {
user: 'sa',
password: 'EnakAja123',
server: '192.168.1.37',
database: 'Angular'
};
app.use(function (req, res, next) {
res.setHeader('Access-Control-Allow-Origin', '*');
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
res.setHeader('Access-Control-Allow-Credentials', false);
next();
});
app.post('/user', function (req, res) {
// connect to your database
sql.connect(config, function (err) {
if (err) console.log(err);
// create Request object
var request = new sql.Request();
// query to the database and get the records
request.input('username', req.body.username) <<
request.input('password', req.body.password) <<
request.query('select * from Angular_user where username = #username and password = #password', function (err, recordset) {
if (err) console.log(err)
// send records as a response
res.send(recordset);
});
});
});
var server = app.listen(5000, function () {
console.log('Server is running..');
});
How can I insert a value to this request.body.username and password?
Because I don't know how this request and response works
You should use body-parser with express to parse the request boy. Check body-parser documentation and example.
I'm using NodeJS, ANgularJS, and MongoDB with mongoose to make a website. I'm having some trouble adding an object in mongoDB. The name of the object is Todo.
Here are the models of Todo:
var mongoose = require('mongoose');
var TodoSchema = new mongoose.Schema({
name: String,
password : String,
completed: Boolean,
note: String
});
module.exports = mongoose.model('Todo', TodoSchema);
In the controller I create a new Todo and push it
angular.module('app').controller('Connexion', ['$scope', 'Todos','$location', function($scope,Todos, $location) {
$scope.editing = [];
$scope.todos = Todos.query();
$scope.save = function() {
var todo = new Todos({ name: "test", password: "test", completed: false });
$scope.todos.push(todo);
Todos.save($scope.todo);
}
}]);
This is my html page, each time I click on the button I Have a new todo created and it's displayed on screen:
<button ng-click="save()">Creer POST </button>
<ul>
<li ng-repeat="todo in todos">
{{todo.name}}
{{todo.password}}
</li>
</ul>
But I have a problem, the new object is not added on the database. How can I do it?
This is my files in the back-end :
var express = require('express');
var router = express.Router();
var mongoose = require('mongoose');
var Todo = require('../models/Todo.js');
/* GET /todos listing. */
router.get('/', function(req, res, next) {
Todo.find(function (err, todos) {
if (err) return next(err);
res.json(todos);
});
});
/* POST /todos */
router.post('/', function(req, res, next) {
Todo.create(req.body, function (err, post) {
if (err) return next(err);
res.json(post);
});
});
/* GET /todos/id */
router.get('/:id', function(req, res, next) {
Todo.findById(req.params.id, function (err, post) {
if (err) return next(err);
res.json(post);
});
});
/* PUT /todos/:id */
router.put('/:id', function(req, res, next) {
Todo.findByIdAndUpdate(req.params.id, req.body, function (err, post) {
if (err) return next(err);
res.json(post);
});
});
/* DELETE /todos/:id */
router.delete('/:id', function(req, res, next) {
Todo.findByIdAndRemove(req.params.id, req.body, function (err, post) {
if (err) return next(err);
res.json(post);
});
});
module.exports = router;
And if this can help this the back-end file app.js
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var mongo = require('mongodb');
var Post = require('./models/Post.js');
var routes = require('./routes/index');
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/todoApp', function(err) {
if(err) {
console.log('connection error', err);
} else {
console.log('connection successful');
}
});
var app = express();
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', function(req, res, next){
res.sendFile(__dirname + '/public/index.html');
});
var found = ['DB Connection not yet established. Try again later. Check the console output for error messages if this persists.'];
module.exports = app;
$scope.todo from Todos.save($scope.todo); is not defined so this is why you might not manage to save anything
I am sending http request and when that request is finished I am trying to go to another state but the problem is it does not goes in the success callback I thought my be I'm getting an error so I wrote the error callback it does not goes in that to. Can anybody tell me what am I doing wrong
$scope.submitUpdatedData= function(user){
debugger;
// $http.post('/url',{params: value}).sucess(function(){
API.updateRecord(user).success(function(res){
$state.go('app' ,{} , {reload: true });
console.log("Hello");
});
}
The API code is given below. Here I invoke the http call
.factory('API', function($http) {
var api = {};
var baseURL = 'http://localhost:3000';
api.addRecord = function(record) {
console.log(record);
// $http.post(baseURL + '/addData', {name: record.name}.);
return $http.post(baseURL + '/addData', {rec:record});
};
api.deleteRecord = function(id){
return $http.get(baseURL +'/delete/' + id );
};
api.updateRecord = function(user){
return $http.post(baseURL + "/update/" ,{rec:user});
};
api.getAllRecord = function(){
return $http.get(baseURL+'/getAll');
};
api.getOneRecord = function(id){
return $http.get(baseURL + '/getOne/' + id)
};
return api;
})
UPDATE
I have replaced the .success part with then but it still not works

Seems like success and error are deprecated, you should use then instead:
API.updateRecord(user).then(function(res){
$state.go('app' ,{} , {reload: true });
console.log("Hello");
});
The $http legacy promise methods success and error have been
deprecated. Use the standard then method instead. If
$httpProvider.useLegacyPromiseExtensions is set to false then these
methods will throw $http/legacy error.

Seems like your request is never answered by the API Server. Maybe you can set a timeout for your request. Here it says you can do:
$http.post(url, data, {timeout: 100});
That should timeout your request after 100ms.
