db.tableName.insertMany([{_id: 1, name: 1}, {_id: 2, name: 2}, {_id: 3, name: 3}])
This will insert documents. In case let assume name:2 is already in database, it will insert name:1 and throw error. the name: 3 won’t be inserted in default behaviour. To get new document inserted and skip the already inserted documents, we can use:
db.tableName.insertMany([{_id: 1, name: 1}, {_id: 2, name: 2}, {_id: 3, name: 3}], {ordered: false})
The argument ordered: false will insert document which are not present in the document. By default the ordered is set to true.
mongoimport Downloads/tv-shows.json -d MoviesData -c MoviesCollection --jsonArray
