How to parse email in node js mysql? - mysql

Question

I have created a normal registration form with following fields:
name,email,dob,gender,password
i am using express.js and within post route i access it via
req.body.(param)
console.log(req.body) shows all params.
Now i have mysql table with same columns as mentioned before. If i do insert with plain strings (eg: abcs) it works i.e. value is inserted into mysql table. Also the email in form is username in db.
When I try inserting all the fields it shows error :( unknown username field ). username varchar(50) is its definition. in the logs i see password field's input is surrounded with single quotes but as for email it becomes: ('user#mail'.'com'). I also used knex, alternate ways as mentioned in mysql docs and got same error(unknown username) .
Can someone tell me how should i store email in mysql db via nodejs+express
db.js
var mysql = require('mysql');
// setup mysql
var dbcon = mysql.createConnection({
host: 'localhost',
database: 'test',
user: 'flip',
password: 'flop'
});
dbcon.connect(function (err) {
if (err) throw err;
console.log("Connected to db");
});
module.exports = dbcon;
routes/index.js:
var dbcon = require('../db');
.
.
router.post('/signup', function (req, res) {
console.log(req.body);
/* knex('users').insert( {
user_id: 1,
password: req.body.su_password,
u_firstname: req.body.su_firstname,
u_lastname: req.body.su_lastname,
u_gender: req.body.su_gender,
u_dob: req.body.su_date,
}).then(function(arg){
console.log(arg);
});
*/
dbcon.connect(function (err) {
var sqlv = {
user_id: 1,
password: req.body.su_password,
u_firstname: req.body.su_firstname,
u_lastname: req.body.su_lastname,
u_gender: req.body.su_gender,
u_dob: req.body.su_date
};
/*var sql = "insert into `users` values (?,??,??,??,??,??,??);";
var sqlv = [1,req.body.su_email, req.body.su_password, req.body.su_firstname, req.body.su_lastname, req.body.su_gender, req.body.su_date];
sql = mysql.format(sql,sqlv);
*/
//var sql ="insert into usertmp (`username`,`password`) values ('"+req.body.su_email+"','"+req.body.su_password+"');";
dbcon.query("insert into users values ? ;", sqlv, function (err, result) {
if (err) {
console.log(err);
throw err;
}
console.log("inserted into users " + result);
});
});
res.redirect('/');
});
console.log(req.body) in routes/index.js:
{ su_firstname: 'user',
su_lastname: 'virus',
su_email: 'user#mail.com',
su_gender: 'm',
su_date: '1999-01-01',
su_password: 'passowrd00' }
Error(for current example):
{ Error: ER_PARSE_ERROR: You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right syntax to use near 'user_id = 1, password = 'passowrd00', u_firstname = 'user', u_lastname =' at line 1
Error(for insert using actual sql query with single quotes around each value):
Unhandled rejection Error: ER_BAD_FIELD_ERROR: Unknown column 'username'
in 'field list'

Answer 1

I figured it out !
It wasn't nodejs/expresjs mistake it was from the database.
In the database i had used triggers and forgot to use NEW/OLD prefixes.
