The Insert is an image inserted into the text. At the same time, Upsert is (computing database) an operation that inserts rows into a database table if they do not already exist or updates them if they do.
In MongoDB, UPSERT is an option used during the update process. update (), findAndModify (), etc. In other words, UPSERT is a combination of update and insert (update + Insert = Upsert). If the value of this option is set to true and one or more documents are found that match the specified query, the update operation updates the matching one or more documents. Alternatively, suppose the value of this option is set to true, and no document matches the specified document. In that case, this option inserts a new document into the collection, and this new document has the fields specified in operation.
By default, the value of the UPSERT option is false. If the value of UPSERT is true for a fragmented collection, the filter must include the full shared key.
The value of the upsert option is either true or false. Next, let's learn how to use the UPSERT option. Upsert using the findAndModify () method. You can use the upsert option with the findAndModify () method. With this method, the default value for this option is false. Suppose you set the value of this option to true. In that case, the method does one of the following: If one or more documents are found that match the specified query criteria, the findAndModify () method updates one or more documents. If no document/documents match the given query criteria, then the findAndModify() method inserts a new document in the collection.
The insert command inserts one or more documents and returns a document containing the status of all inserts. The insert method provided by the MongoDB driver uses this command internally. The name of the target collection is an array of one or more documents to include in a named collection.
The insert command inserts one or more documents and returns a document containing the status of all inserts. The insert method provided by the MongoDB driver uses this command internally.
Document validation the insert command adds support for the bypassDocumentValidation option. This allows you to bypass document validation when you insert or update a document in a collection using validation rules.
Transaction Inserts can be used within multi-document transactions.
