\n

Anda dapat menggunakan metode berikut untuk menghapus kolom dari setiap dokumen dalam koleksi di MongoDB:<\/span><\/p>\n

Metode 1: hapus bidang<\/strong><\/span><\/p>\n

 db.collection.updateMany({}, { $unset<\/span> : {\" field1<\/span> \":1}})<\/strong><\/pre>\n
 Metode 2: hapus beberapa bidang<\/strong><\/span><\/p>\n
 db.collection.updateMany({}, { $unset<\/span> : {\" field1<\/span> \":1, \" field2<\/span> \":1}})\n<\/strong><\/pre>\n
 Contoh berikut menunjukkan cara menggunakan setiap metode dengan tim<\/span> pengumpulan dengan dokumen berikut:<\/span><\/p>\n
 db.teams.insertOne({team: \" Mavs<\/span> \", position: \" Guard<\/span> \", points: 31<\/span> })<\/strong>\ndb.teams.insertOne({team: \" Spurs<\/span> \", position: \" Guard<\/span> \", points: 22<\/span> })<\/strong>\ndb.teams.insertOne({team: \" Rockets<\/span> \", position: \" Center<\/span> \", points: 19<\/span> })<\/strong><\/pre>\n
 Contoh 1: menghapus bidang<\/strong><\/span><\/h3>\n
 Kita dapat menggunakan kode berikut untuk menghapus bidang \u201cpoin\u201d dari setiap dokumen dalam koleksi kita:<\/span><\/p>\n
 db.teams.updateMany({}, { $unset<\/span> : {\" points<\/span> \":1}})<\/strong><\/pre>\n
 Kami kemudian dapat menggunakan kueri berikut untuk menampilkan setiap dokumen dalam koleksi kami:<\/span><\/p>\n
 db.teams.find()<\/strong><\/pre>\n
 Kueri ini mengembalikan hasil berikut:<\/span><\/p>\n
 { _id: ObjectId(\"61893b7196cd2ba58ce928f4\"),\n  team: 'Mavs',\n  position: 'Guard' }\n\n{ _id: ObjectId(\"61893b7196cd2ba58ce928f5\"),\n  team: 'Spurs',\n  position: 'Guard' }\n\n{ _id: ObjectId(\"61893b7196cd2ba58ce928f6\"),\n  team: 'Rockets',\n  position: 'Center' }<\/strong><\/pre>\n
 Perhatikan bahwa bidang \u201cpoin\u201d telah dihapus dari setiap dokumen.<\/span><\/p>\n
 Contoh 2: hapus beberapa bidang<\/strong><\/span><\/h3>\n
 Kita dapat menggunakan kode berikut untuk menghapus kolom \u201ctitik\u201d dan \u201cposisi\u201d dari setiap dokumen dalam koleksi kita:<\/span><\/p>\n
 db.teams.updateMany({}, { $unset<\/span> : {\" points<\/span> \":1, \" position<\/span> \":1}})<\/strong><\/pre>\n
 Kami kemudian dapat menggunakan kueri berikut untuk menampilkan setiap dokumen dalam koleksi kami:<\/span><\/p>\n
 db.teams.find()<\/strong><\/pre>\n
 Kueri ini mengembalikan hasil berikut:<\/span><\/p>\n
 { _id: ObjectId(\"61893bf896cd2ba58ce928f7\"), team: 'Mavs' }\n{ _id: ObjectId(\"61893bf896cd2ba58ce928f8\"), team: 'Spurs' }\n{ _id: ObjectId(\"61893bf896cd2ba58ce928f9\"), team: 'Rockets' }<\/strong><\/pre>\n
 Perhatikan bahwa bidang \u201ctitik\u201d dan \u201cposisi\u201d telah dihapus dari setiap dokumen.<\/span><\/p>\n
