node.js - how to find the distinct values of a field in a MongoDB collection using Node MongoClient -
in mean application, need find distinct values of field named "datafields" collection "fixed_asset_register", using (non-mangoose) mongoclient:
var mongodb = require('mongodb'); var assert = require('assert'); var mongoclient = mongodb.mongoclient; mongoclient.connect(url, function (err, db) { if (err) { console.log('unable connect mongodb server. error:', err); } else { console.log('connection established to', url); var collection = db.collection('fixed_asset_register'); var distictdatafieldsvalue = ? }
what proper syntax distinct values of field named "datafields"?
i solved issue using collection.distinct:
collection.distinct("datafields",(function(err, docs){ console.log(docs); assert.equal(null, err); db.close(); }))
