upsert() [2/2]

update & mongocxx::v_noabi::options::update::upsert

(

bool

upsert

Sets the upsert option.

By default, if no document matches the filter, the update operation does nothing. However, by specifying upsert as true, this operation either updates matching documents or inserts a new document using the update specification if no matching document exists.

Parameters

upsert

If set to true, creates a new document when no document matches the query criteria. The server-side default is false, which does not insert a new document if a match is not found.

Returns

A reference to the object on which this member function is being called. This facilitates method chaining.
