Hy everyone
I'm a new developer ReactJS. I tried to set up Firebase into my backend and I've a problem with my frontend. If I'm running my API using a postman, my API work and send a message from my backend but if I running my code from frontend I got error like this Column in the table is users and is not undefined
{ error: column "undefined" does not exist

and this is my backend code
Orders.patch([ Object.assign({id: req.params.id}, req.body) ])
.then(orders => {
DB.query("SELECT oauth FROM users WHERE id = "+req.body.driver+" OR id = "+req.body.customer+"").then(res=>{
res.map((row,i)=>{
let tmp = {
token: row.oauth.token
}
res[i] = tmp;
});
// console.log(res);
const arrayToken = res.map(function (obj) {
return obj.token;
});
// console.log(arrayToken);
const message = {
// to: res[0].token,
registration_ids: arrayToken,
notification: {
body: "Hey! you got update order notification."
}
};
fcm.send(message, function(err, response){
console.log(response);
})
}).catch(err => console.log(err));
jsonData = util.jsonData(null, orders);
res.json(jsonData);
})
.catch(err => {
jsonData = util.jsonData(400);
res.status(jsonData.code).json(jsonData);
})
})
So how to fixed it and can you help me explain error of my code ?
Error is here
WHERE id = "+req.body.driver+" OR id = "+req.body.customer+"
You need to use defined variables in this scope

I followed the tutorial from youtube and I found an error like this and I don't know where the problem is. When i run node my_bot.js, Then there is an error DiscordAPIError: Missing Access.
I've tried a few things. My expectation will appear the words Hello World on discord. The result is an error.
I think, there is nothing wrong with my code
const { Client, Intents } = require('discord.js');
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });
client.on('ready', () => {
console.log("Connected as " + client.user.tag)
client.user.setActivity('you', { type: 'WATCHING' });
client.guilds.cache.forEach((guild) => {
console.log(guild.name);
guild.channels.cache.forEach((channel) => {
console.log(` - ${channel.name} ${channel.type} ${channel.id}`)
})
// General channel id: 956453625889185826
})
let generalChannel = client.channels.cache.get("956453625889185826")
generalChannel.send("Hello World")
})
client.login("XXXXXXXXXXXXXXXXXXXXX")
Result:

As the error says, Missing access means that your bot doesn't have the permissions to send a message in the channel.
Make sure your bot has the Send message permission in the channel you want to send the message
My code looks like this
signup.post('/signup', urlendcodedParser, async(req: Request, res: Response) => {
const username = req.body.username;
const password = req.body.password;
const age = req.body.age;
const email = req.body.email;
const fullname = req.body.fullname;
console.log(req.body)
await pool.query("INSERT INTO (username, userpassword, email, fullname, age) VALUES ($1, $2, $3, $4, $5) RETURNING *", [username, password ,email, fullname, age]).catch(err => console.log(err))
await res.json("Akaunt napravljen")
})
But when I try to submit a POST request I get this error:
error: syntax error at or near "("

How can I fix this?
You're missing the table name.
INSERT INTO table_name (username, userpassword, email)...
My code looks like this:
app.delete("/delete/:id", urlencodedParser, (req: Request, res: Response) => {
const id: any = req.params
console.log(req.params)
pool.query(`DELETE FROM allusers WHERE userid = $1`, [id]).catch(err => {
console.log(err)
})
})
But when I test it whit postman and go on e.g localhost:5000/delete/1 it logs:
error: syntax error at or near "["

I've written a code to fetch the data from postgres database using express and NODE.js. the database is connected with the backend code but still it is showing error like relation does not exit.
Please check the code and error that I got:
var express = require('express');
var pg = require("pg");
var app = express();
var connectionString = "postgres://postgres:postgres#localhost:5432/testDatabase?currentSchema=testSchema";
app.get('/', function(req, res, next) {
pg.connect(connectionString, function(err, client, done) {
if (err) {
console.log("Not able to get Connection " + err);
res.status(400).send(err);
} else {
console.log("Connected.!");
}
const
query = {
// give the query a unique name
name : 'fetch-user-details',
text : 'SELECT * FROM loginTable',
}
client.query(query, function(err, result) {
done(); // closing the connection;
if (err) {
console.log(err);
res.status(400).send(err);
}
res.status(200).send(result.rows);
});
});
});
app.listen(4000, function() {
console.log('Server is running.. on Port 4000');
});
and the error response that I got is like:
Server is running.. on Port 4000
Connected.!

just run this db dump at my Postgres
CREATE SCHEMA "testSchema";
ALTER SCHEMA "testSchema" OWNER TO postgres;
SET search_path = "testSchema", pg_catalog;
SET default_tablespace = '';
SET default_with_oids = false;
CREATE TABLE "loginTable" ( "ID" numeric NOT NULL, "Name" text );
ALTER TABLE "loginTable" OWNER TO postgres;
this was the problem
change your query to this
query = {
// give the query a unique name
name : 'fetch-user-details',
text : `SELECT * FROM "testSchema".logintable`,
}
you should mention the schema name
tasted on
Ubuntu
postgres 10.6
pg: 6.4.2
node v10.14.1
i am super new to postgres and trying to do a simple select query.
my table looks like:
create table push_table
(
seq_id int,
device_id text,
primary key (seq_id),
user_id varchar(100)
);
and my nodejs code as follows:
pool.connect(function (err, client, done)
{
if (err) console.log(err)
myClient = client
//query if the user exists
var ageQuery = format('SELECT * from push_table WHERE user_id = ' + userId);
myClient.query(ageQuery, function (err, result) {
if (err) {
console.log(err)
}
console.log("number of rows:" + result.rows.length);
});
});
on running nodejs server log prints:

The column user_id is varchar:
user_id varchar(100)
so a valid SQL query must use single quotes to define the varchar value, e.g.:
SELECT * from push_table WHERE user_id = 'Vik'
Your code does not provide the quotes needed.
