When attempting to connect to my local SQL Server instance I am receiving an error stating Authentication failed for login. However I am able to login directly to the server in SQL using the provided login.
Here is my code that is attempting to connect to the server.
var Sequelize = require('sequelize');
const sequelize = new Sequelize('GraphQLTests', 'gql', 'Password1', {
dialect: 'mssql',
host:'localhost'
});
sequelize
.authenticate()
.then(() => {
console.log('Connection has been established successfully.');
})
.catch(err => {
console.error('Unable to connect to the database:', err);
});
I have printed to the console in the Sequelize code to verify that the correct credentials are getting passed but still receive this error.
name: 'SequelizeAccessDeniedError',
parent:
{ ConnectionError: Login failed for user ''.}
Please let me know if there is any other info I can provide.
try this
const sequelize = new Sequelize('DB Name', 'Username', 'Password', {
host: 'Host',
dialect: 'mssql',
dialectOptions: {
options: {
encrypt: true,
}
}
});
sequelize.authenticate().then((err) => {
console.log('Connection successful', err);
})
.catch((err) => {
console.log('Unable to connect to database', err);
});

This is what worked for me, where I have put the server details in an YAML file. (this way, you can switch servers on the fly).
this is the sequelize code
//get the configure from the YAML file
const YAML = await fs.readFile(process.env.SEQUELIZE_CONNECT,'utf8');
//load the database parameters into our system
const params = jsyaml.safeLoad(YAML, 'utf8');
//initiate our database server details to connect to our underlying database system
//as described in the YAML file.
sequlz = new Sequelize(params.dbname, params.username, params.password, params.params);
Here is how my YAML file looks. (I have left my code comments as it is)
#this should work to whatever you are using anywhere.
#as per the YAML file title, I am using a MS SQL server hosted on Azure.
# you can edit values. as per your requirement.
# check the dialect help file of your server on the sequelize documentation
# https://sequelize.org/v5/file/lib/dialects/mssql/connection-manager.js.html
#change the values as per your server.
dbname: databasenamehere
username: usernamehere
password: passwordhere
params:
host: servernamehere.database.windows.net
dialect: mssql
dialectOptions:
{
options: {
encrypt: true,
requestTimeout: 10000
}
}
So, that worked for me. (I have remixed answers from above post, and also from the textbook and multiple online resources I was referring).
Note : The server is running on Azure with the Firewall IP address set to ALL IP address.

I have a free ClearDB account that I got through Heroku (as a resource)
It gives me the
CA certificate
Client cert
Client Key
These are all in .pem format
const fs = require('fs');
const ssl = {
ca: fs.readFileSync('cleardb-ca.pem', "utf-8"),
key: fs.readFileSync('cleardb-key.pem', "utf-8"),
cert: fs.readFileSync('cleardb-cert.pem', "utf-8")
};
const cleardb = mysql.createConnection({
host:"HOST",
user: "USER",
password: "PWD",
database: "DB",
ssl: ssl
});
cleardb.connect((err) => {
if (err) throw err;
console.log('connected!');
});
This keeps throwing
Error: 22928:error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol:c:\ws\deps\openssl\openssl\ssl\statem\statem_lib.c:1929:
and then the error stacktrace shows an Object like
library: 'SSL routines', function: 'ssl_choose_client_version', reason: 'unsupported protocol', code: 'HANDSHAKE_SSL_ERROR', fatal: true
The SSL routines:ssl_choose_client_version:unsupported error is the same exact error I get when I try connecting to this DB through the MySQL CLI.
I.e. mysql --host=HOST --ssl-capath=. --ssl-cert=cleardb-cert.pem --ssl-key=cleardb-key.pem --user=USER
I'm able to connect through both Node and the CLI if I do not use SSL.
Any idea what's going on here?
Should I really worry that much about using SSL? I've read that if the option for transport security exists, that you should elect to use it.
i have a remote mongo server and i want to connect to that with nodejs . i tried connecting directly with mongo shell and it was ok ... but i cant connect to that mongodb server in nodejs ..
the mongo command for connection :
mongo --host 192.168.10.33 --port 27017 -u mohammad -p "mypassw#12" --authenticationDatabase=access
i only want to convert that command into nodejs connection config..
something like:
uri = mongodb://mohammad:mypassw#12#192.168.10.33:27017/"
The URI should be encoded
uri = "mongodb://mohammad:mypassw%4012#192.168.10.33:27017/access"
mongo.connect(uri, { useNewUrlParser: true }, (err, db) => {});
Connecting to a remote Mongo can sometimes be tricky , mongoose can help a great lot with connecting to your remote db . The code below should be able to do the trick and connect .
const mongoose = require('mongoose');
mongoose.set('useFindAndModify', false);
const uri = "mongodb+srv://user:pass#clusterName.d4zrk.mongodb.net/databaseName?retryWrites=true&w=majority";
mongoose.connect(uri, { useNewUrlParser: true, useUnifiedTopology: true })
const db = mongoose.connection
db.on('error', (err) => {
console.log(err)
})
db.once('open', () => {
console.log('Database Connection Established!')
})
I guess the issue might be with your password, it looks like to contains a special character that is used by the mongodb driver to separate the credentials from the host:
mongodb://[username:password#]host1[:port1][,...hostN[:portN]][/[defaultauthdb][?options]]
If you have a # in your password, you have to apply an percent encoding it by adding a % character.
Here is the list of character to encode according to mongodb driver documentation: : / ? # [ ] #
I have been working with nodejs google cloud functions for a while. I have been facing a weird issue where I can't connect to database servers and there is no error logged not even timeout. I am using node v14.2.0 with pg as postgres library. My nodejs code is
const { Client } = require('pg');
let connectionSetting = {
host: "host",
user: "user",
database: "db_name",
password: "password",
};
const client = new Client(connectionSetting);
console.log(connectionSetting);
client.connect(err => {
if (err) {
console.error(`Error connecting to db -> ${err}`);
}
console.log("Connection established with PgSql DB ");
});
There are no console logs or whatever.
This same code is working on other systems. The database is remote database hosted on gcp and I'm able to connect to it using tablePlus as GUI client.
Any help appreciated.
I found the issue. It has to do with the node version. I was using node current 14.2.0 so I installed node lts 12 and then everything works fine.
Thanks for all help
I'm trying to establish a simple connection to my database with the mysql npm package. At first glance, everything works fine and I can get the information I need, however, if I leave the server running for some time I get the following error:
Error: read ECONNRESET
at TCP.onStreamRead
const express = require('express');
const app = express();`
const mysql = require('mysql');
const db = mysql.createConnection({
host: 'XXXX.mysql.database.azure.com',
user: 'XXXXX',
password: 'XXXXX',
database: 'XXXXX'
})
db.connect((err)=>{
if(err){
console.log(err.message);
} else {
console.log('Connected to the database');
}
})
As far as I understand the problem stems from the database connection being in idle mode. Do I need to configure the Azure server or is there something else I need to do?
Couple of things to try:
You can try creating connection pool instead of **createConnection**
mysql.createPool({});
Modify your package.json like below:
"dependencies": {
"mysql": "git://github.com/mysqljs/mysql#e3e123e9af7c0829a6c1417d911572a75b4a5f95"
},
It is described in detail here:
Bad handshake or ECONNRESET Azure Mysql Nodejs

Hope it helps.
I'm starting at Node.js and i'm trying to make a simple connection with Sequelize based on its documentation (http://docs.sequelizejs.com/manual/installation/getting-started.html#installation).
Here my db.js file :
const Sequelize = require('sequelize')
const db = new Sequelize('chat','root','root',{
host: 'localhost',
port: 3306,
dialect: 'mysql'
});
db
.authenticate()
.then(() => {
console.log('Connection has been established successfully.');
})
.catch(err => {
console.error('Unable to connect to the database:', err);
});
When executing this code, I have no success nor error message, just a message indicating 'String base operators deprecated' but nothing important i think.
I tried changing localhost to 127.0.0.1, remove port number and multiples thread but i'm stucked here...
Tested your code and all seemed to work fine, it connected successfully to the database instance I have running.
You might want to ensure mysql2 package is installed. Also check that the database chat has been created in MySQL workbench, and ensure the password is correct.
