NAME

       mongoc_database_write_command_with_opts - mongoc_database_write_command_with_opts()

SYNOPSIS

          bool
          mongoc_database_write_command_with_opts (mongoc_database_t *database,
                                                   const bson_t *command,
                                                   const bson_t *opts,
                                                   bson_t *reply,
                                                   bson_error_t *error);

       Execute  a  command on the server, applying logic that is specific to commands that write,
       and taking the MongoDB server version into account. To send a raw command  to  the  server
       without any of this logic, use mongoc_database_command_simple().

       Use  this  function  for  commands  that write such as "drop" or "createRole" (but not for
       "insert", "update", or "delete", see Basic Write Operations). Write concern and  collation
       can be overridden by various sources. In a transaction, read concern and write concern are
       prohibited in opts. The highest-priority sources for these options are listed first in the
       following table. The write concern is omitted for MongoDB before 3.4.

                                      │Write Concern │ Collation │

                                      │database      │           │
                                      └──────────────┴───────────┘

       See the example for transactions and for the "distinct" command with opts.

       reply is always initialized, and must be freed with bson_destroy().

PARAMETERS

       • database: A mongoc_database_t.

       • db_name: The name of the database to run the command on.

       • command: A bson_t containing the command specification.

       • opts: A bson_t containing additional options.

       • reply: A location for the resulting document.

       • 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     database,     and     use
         mongoc_client_session_append()  to  add  the  session  to opts. See the example code for
         mongoc_client_session_t.

       • 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.

       • serverId: To target a specific server, include an int32 "serverId" field. Obtain the  id
         by  calling  mongoc_client_select_server(),  then  mongoc_server_description_id() on its
         return value.

       Consult the MongoDB Manual entry on Database Commands for each command's arguments.

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.

BASIC WRITE OPERATIONS

       Do  not  use  this  function  to  call  the  basic  write commands "insert", "update", and
       "delete".    Those    commands    require    special    logic    not    implemented     in
       mongoc_database_write_command_with_opts.  For  basic  write  operations use CRUD functions
       such as mongoc_collection_insert_one() and the others described in the CRUD  tutorial,  or
       use the Bulk API.

EXAMPLE

       See the example code for mongoc_client_read_command_with_opts().
