\n

Anda dapat menggunakan sintaks berikut untuk mencantumkan semua nama bidang dalam koleksi di MongoDB:<\/span><\/p>\n

 Object. keys<\/span> (db.myCollection.findOne())\n<\/strong><\/pre>\n
 Contoh khusus ini mencantumkan semua nama bidang dalam koleksi bernama myCollection<\/span> .<\/span><\/p>\n
 Contoh berikut memperlihatkan cara menggunakan sintaksis ini dalam praktik dengan<\/span> tim<\/span> koleksi dengan dokumen berikut:<\/span><\/p>\n
 db.teams.insertOne({team: \" Mavs<\/span> \", points: 30, rebounds: 8, assists: 2})\ndb.teams.insertOne({team: \" Mavs<\/span> \", points: 35, rebounds: 12, assists: 6})\ndb.teams.insertOne({team: \" Spurs<\/span> \", points: 20, rebounds: 7, assists: 8})\ndb.teams.insertOne({team: \" Spurs<\/span> \", points: 25, rebounds: 5, assists: 9})\ndb.teams.insertOne({team: \" Spurs<\/span> \", points: 23, rebounds: 9, assists: 4})\n<\/strong><\/pre>\n
 Contoh: Cantumkan semua nama field di MongoDB<\/strong><\/span><\/h3>\n
 Kode berikut memperlihatkan cara mencantumkan semua nama bidang dalam koleksi Teams<\/span> :<\/span><\/p>\n
 Object. keys<\/span> (db.teams.findOne())<\/strong><\/pre>\n
 Kueri ini mengembalikan dokumen berikut:<\/span><\/p>\n
 [ '_id', 'team', 'points', 'rebounds', 'assists' ]<\/strong><\/pre>\n
 Perhatikan bahwa daftar nama bidang juga menyertakan bidang _id<\/strong> , yang secara otomatis dihasilkan MongoDB untuk setiap dokumen.<\/span><\/p>\n
 Catatan<\/strong> : Untuk mencantumkan nama field di koleksi lain, cukup ganti nama tim<\/span> dengan nama lain.<\/span><\/p>\n
 Sumber daya tambahan<\/strong><\/span><\/h3>\n
