You are mixing here callback with promises. To reach what you want, wrap your function in a promise:
function getID(){
return new Promise((resolve, reject) => {
let sql = 'SELECT * from id'
connection.query(sql, (err, rows) => {
if (err){
reject(err)
}else{
resolve(rows);
}
})
})
}
let list = getCredit();
list.then(console.log);
console.log(list)
