inserting id to postgresql query using node.js

Question

 var Integer = require('integer'); client.query('INSERT INTO users (id, first_name, last_name, email, password, phone_number) VALUES ($1, $2, $3, $4, $5, $6)', [Integer(), req.body.firstName, req.body.lastName, req.body.username, pwd, req.body.phoneNumber]

This is my function where I trying to post id to my postgreqsl table. I installed integer for node by npm, set integer data type for my id column in pg and it does not work when i was trying to put it into the database.

I had a such error:

{ error: invalid input syntax for integer: "{"high":0,"low":0}"

When I imported uuivdv4 to the file and changed the Integer() by uuidv4(),(of course i remember about changing data type in id column) i had a good insert.

 const uuidv4 = require('uuid/v4'); client.query('INSERT INTO users (id, first_name, last_name, email, password, phone_number) VALUES ($1, $2, $3, $4, $5, $6)', [uuidv4(), req.body.firstName, req.body.lastName, req.body.username, pwd, req.body.phoneNumber]

Answer 1

integer package is not intended to generate a random integer number like that of uuid/v4 , which generates a random UUID string. The integer is meant for converting a string literal to number eg '123' to 123 .

The below will work for you.

Updated code:

let randNumber= Math.floor(Math.random() * 10000000000);
client.query('INSERT INTO users (id, first_name, last_name, email, password, phone_number) VALUES ($1, $2, $3, $4, $5, $6)', [randNumber, req.body.firstName, req.body.lastName, req.body.username, pwd, req.body.phoneNumber]

EDIT : Change the column Id in your users to auto-increment and use the below query to insert.

client.query('INSERT INTO users (first_name, last_name, email, password, phone_number) VALUES ($1, $2, $3, $4, $5)', [req.body.firstName, req.body.lastName, req.body.username, pwd, req.body.phoneNumber]

After you have changed it to autoincrement , no need to specify the id for inserting.
