NAMEmongoc_collection_replace_one − mongoc_collection_replace_one()
SYNOPSIS bool
mongoc_collection_replace_one (mongoc_collection_t *collection,
const bson_t *selector,
const bson_t *replacement,
const bson_t *opts,
bson_t *reply,
bson_error_t *error);
PARAMETERS • collection: A mongoc_collection_t. • selector: A bson_t containing the query to match the document for updating. • replacement: A bson_t containing the replacement document. • reply: Optional. An uninitialized bson_t populated with the update 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: 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. • bypassDocumentValidation: Set to true to skip server−side schema validation of the provided BSON documents. • collation: Configure textual comparisons. See Setting Collation Order, and the MongoDB Manual entry on Collation. Collation requires MongoDB 3.2 or later, otherwise an error is returned. • hint: A document or string that specifies the index to use to support the query predicate. • upsert: When true, creates a new document if no document matches the query.
DESCRIPTIONThis function shall replace documents in collection that match selector with replacement. If provided, reply will be initialized and populated with the fields matchedCount, modifiedCount, upsertedCount, and optionally upsertedId if applicable. 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().
SEE ALSOMongoDB update command documentation for more information on the update options. mongoc_collection_update_one mongoc_collection_update_many
ERRORSErrors are propagated via the error parameter.
RETURNSReturns 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.
