MONGOC_COLLECTION_INSERT_ONE(3) libmongoc MONGOC_COLLECTION_INSERT_ONE(3) 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 con- tain 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 col- lection, 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 docu- ments. * 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 valida- tion 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 pass a non-NULL reply, it is filled out with an "insertedCount" field. If the document was successfully inserted, reply will also contain an "insertedId" field containing the inserted document's _id. If there is a server error then reply contains either a "writeErrors" array with one sub- document 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 in- valid arguments or a server or network error. A write concern timeout or write concern error is considered a failure. AUTHOR MongoDB, Inc COPYRIGHT 2009-present, MongoDB, Inc. 1.30.8 Aug 27, 2026 MONGOC_COLLECTION_INSERT_ONE(3)
