Insert into mysql database, nodejs separates value - mysql

Question

I want to insert into my table values which I get from my front.
so. I have
const Workers = function (workers) {
this.id = workers.id,
this.workers = workers.workers,
this.room = workers.room,
this.team = workers.team,
this.city = workers.city,
this.hotel_name = workers.hotel_name,
this.address = workers.address
};
Workers.create = (newWorkers, result) => {
sql.query(`INSERT INTO rooms_split (workers, room, hotel_name, address, createdAt, updatedAt) VALUES( ? , ? , ? , ?, DEFAULT, DEFAULT )`,
[newWorkers.workers, newWorkers.room, newWorkers.hotel_name, newWorkers.address], (err, res) => {
if (err) {
console.log("error: ", err);
result(err, null);
return;
}
console.log("created splitted room: ", {
id: res.insertId,
...newWorkers
});
result(null, {
id: res.insertId,
...newWorkers
});
});
};
And there is my controller
exports.create = (req, res) => {
console.log("body " + JSON.stringify(req.body));
if (!req.body) {
res.status(400).send({
message: "Content can not be empty!"
});
}
const workers = new Workers({
workers: req.body.workers,
room: req.body.room,
hotel_name: req.body.hotel_name,
address: req.body.address
});
Workers.create(workers, (err, data) => {
if (err)
res.status(500).send({
message: err.message || "Some error occurred while creating the Alias."
});
else res.send(data);
});
}
Output from
console.log("body " + JSON.stringify(req.body));
is
body {"workers":["John Snow","Juri Boyka"],"room":"45","hotel_name":"Test Hamburg","address":"Hamburg 5, test Strase"}
and it looks fine but when is time to insert it into table I got error
code: 'ER_PARSE_ERROR',
errno: 1064,
sqlMessage: "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 ''Juri Boyka', `room` = '45', `team` = NULL, `city` = NULL, `hotel_na' at line 1",
sqlState: '42000',
index: 0,
sql: "INSERT INTO rooms_split SET `id` = NULL, `workers` = 'John Snow', 'Juri Boyka', `room` = '45', `team` = NULL, `city` = NULL, `hotel_name` = 'Test Hamburg', `address` = 'Hamburg 5, test Strase'"
}
I kniw what this error means but I have no idea why when I want to make query nodejs(?) separates my value so instead ['something','something2'] I got 'something', 'something2' and he is right that there are not enough columns

Change
[newWorkers.workers, newWorkers.room, newWorkers.hotel_name, newWorkers.address]
to
[newWorkers.workers.join(), newWorkers.room, newWorkers.hotel_name, newWorkers.address]
since the workers data type in MySQL is varchar. Therefore, you'll need to stringify your incoming workers array
