mongoc_collection_insert_one()

Synopsis

bool
mongoc_collection_insert_one (mongoc_collection_t *collection,
                              const bson_t *document,
                              const bson_t *opts,
                              bson_t *reply,
                              bson_error_t *error);

Parameters

• collection: A mongoc_collection_t.

• document: A bson_t.

• reply: A maybe-NULL pointer to overwritable storage for a bson_t to contain the results.

• error: An optional location for a bson_error_t or NULL.

opts may be NULL or a BSON document with additional command options:

• writeConcern: Construct a mongoc_write_concern_t and use mongoc_write_concern_append() to add the write concern to opts. See the example code for mongoc_client_write_command_with_opts().

• sessionId: First, construct a mongoc_client_session_t with mongoc_client_start_session(). You can begin a transaction with mongoc_client_session_start_transaction(), optionally with a mongoc_transaction_opt_t that overrides the options inherited from collection, and use mongoc_client_session_append() to add the session to opts. See the example code for mongoc_client_session_t.

• validate: Construct a bitwise-or of all desired bson_validate_flags_t. Set to false to skip client-side validation of the provided BSON documents.

• comment: A bson_value_t specifying the comment to attach to this command. The comment will appear in log messages, profiler output, and currentOp output. Requires MongoDB 4.4 or later.

• bypassDocumentValidation: Set to true to skip server-side schema validation of the provided BSON documents.

Description

This function shall insert document into collection.

To insert an array of documents, see mongoc_collection_insert_many().

If no _id element is found in document, then a bson_oid_t will be generated locally and added to the document. If you must know the inserted document’s _id, generate it in your code and include it in the document. The _id you generate can be a bson_oid_t or any other non-array BSON type.

If you pass a non-NULL reply, it is filled out with an “insertedCount” field. If there is a server error then reply contains either a “writeErrors” array with one subdocument or a “writeConcernErrors” array. The reply must be freed with bson_destroy().

Errors

Errors are propagated via the error parameter.

Returns

Returns true if successful. Returns false and sets error if there are invalid arguments or a server or network error.

A write concern timeout or write concern error is considered a failure.
