GET / MySQL Node.js

[acrossmindanduniverse]

I'm a newbie to mysql, so is there possible to GET data by row and GET data from all of my tables in one function?
here's my code:

getAllBooksModel: function(detail) {
return new Promise ((resolve, reject) => {
if (detail) {
connection.query('SELECT * FROM books WHERE ?', [detail], function (err, res) {
if (err) {
reject(err)
} else {
resolve(res)
console.log(res)
}
})
} else {
connection.query('SELECT * FROM books', function (err, res) {
if (err) {
reject(err)
} else {
resolve(res)
console.log(res)
}
})
}
})
}
