) |
Constructs an update operation that will replace a single document matching the filter.

replace_one& mongocxx::model::replace_one::upsert | ( | bool | upsert | ) |
Sets the upsert option.
When upsert is true
, this operation will insert the replacement document as a new document if no existing documents match the filter. When upsert is false
, the replacement operation does nothing if there are no matching documents. By default, upsert is false
.
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. |
