mongoc_collection_insert_many()¶

Synopsis¶

bool
mongoc_collection_insert_many (mongoc_collection_t *collection,
                               const bson_t **documents,
                               size_t n_documents,
                               const bson_t *opts,
                               bson_t *reply,
                               bson_error_t *error);

Parameters¶

collection: A mongoc_collection_t.
documents: An array of pointers to bson_t.
n_documents: The length of documents.
reply: Optional. An uninitialized bson_t populated with the insert result, or NULL.
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: Construct a mongoc_client_session_t with mongoc_client_start_session() 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.
ordered: set to false to attempt to insert all documents, continuing after errors.
bypassDocumentValidation: Set to true to skip server-side schema validation of the provided BSON documents.

Description¶

Insert documents into collection.

To insert a single document, see mongoc_collection_insert_one().

For any document that does not have an “_id” field, 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.
