Get latest MongoDB record by field of datetime
I have a collection like this: { 'datetime': some-date, 'lat': '32.00', 'lon': '74.00' }, { 'datetime': some-date, 'lat': '32.00', 'lon': '74.00' } How can I get the latest record from MongoDB, where the datetime is the latest one? I want only a single record. Use sort and limit : db.col.find().sort({"datetime": -1}).limit(1) For node.js you can use the findOne() function: db.collection('yourCollectionName').findOne( {}, { sort: { datetime: -1 } }, (err, data) => { console.log(data); }, ); 来源： https://stackoverflow.com/questions/21971710/get-latest-mongodb-record-by-field-of-datetime
