How to select a specific record by Id in a database using sequelize?
I would like to select a record from a mysql database by "id" using sequelize. I currently can do it with a mysql query and it works but I am receiving a null result when attempting to do it in sequelize. Here is the query in my mysql which works and the query in sequelize which does not work. What am I doing wrong with the syntax in the sequelize version?

router.get("/station/numbe
db.query(
"SELECT * FROM stores WHERE id = ?",
[req.params.id],
(err, rows, fields) => {
if (!err) res.send(rows);
else console.log(err);
}
);
});
(2)
router.get("/station/numbe
Store.findOne ({
where: {id:'?'}})
.then(data=>{
res.send({stores:data})
})
.catch(err => console.log(err)));

What do most developers use instead of sequelize?
I like the idea of being able to use the same code across various databases..ie. Mysql, Firebase, MariaDb, Postgre....etc. you can plug in quickly.

Jim.....Here is a solution I tracked down.....
router.get("/station/numbe
Store.findByPk(req.params.
.then(stores =>{
res.json(stores);
})
.catch(err => {
console.log(err);
res.status(500).json({msg:
}));

Store.findByPk(req.params.
.then(stores =>{
res.json(stores);
})
.catch(err => {
console.log(err);
res.status(500).json({msg:
}));

It use to be .......findById..........b
I have a passing familiarity with sequelize, but would definitely call myself an Expert on the subject. Reading the documentation for findOne is where I noticed the issue. findByPk is probably the best solution for your specific request. Did my suggestion not work?
ASKER
Yes...it worked.......I will mark it as the solution however, I have other routes written in sql query which I would like help with to convert them to sequelize......can I count on your assistance Sir?
I'll do what I can. Send me a direct message with a link to the questions you create and I will see how I can assist you.
