I Need help to retrieve last record from my collection. I have this code:
db.collection('bbb1collection', function(err, collection) {
collection.find({}).sort({_id:-1}).limit(1).toArray(function(err, results) {
path = results;
console.log(results);
}
使用此查询:
db.users.find().limit(1).sort({$natural:-1})
Check out this:
db.collection('bbb1collection', function(err, collection) {
collection
.find()
.sort({$natural: -1})
.limit(1)
.next()
.then(
function(doc) {
console.log(doc);
},
function(err) {
console.log('Error:', err);
}
);
});
read about $natural
here
return new Promise(async (resolve, reject) => { db.get().collection('bbb1collection').find().sort({$natural:-1}).limit(1).next().then((res) => { console.log(res) resolve(res) }); });
