NAME

6       mongoc_collection_command_with_opts       -      mongoc_collection_com‐
7       mand_with_opts()

SYNOPSIS

10          bool
11          mongoc_collection_command_with_opts (
12             mongoc_collection_t *collection,
13             const bson_t *command,
14             const mongoc_read_prefs_t *read_prefs,
15             const bson_t *opts,
16             bson_t *reply,
17             bson_error_t *error);
18
19       Execute a command on the server, interpreting  opts  according  to  the
20       MongoDB server version. To send a raw command to the server without any
21       of this logic, use mongoc_client_command_simple.
22
23       Read preferences, read and write concern, and collation can be overrid‐
24       den  by various sources. The highest-priority sources for these options
25       are listed first:
26
27            ┌─────────────────┬──────────────┬───────────────┬───────────┐
28            │Read Preferences │ Read Concern │ Write Concern │ Collation │
29            ├─────────────────┼──────────────┼───────────────┼───────────┤
30            │read_prefs       │ opts         │ opts          │ opts      │
31            ├─────────────────┼──────────────┼───────────────┼───────────┤
32            │Transaction      │ Transaction  │ Transaction   │           │
33            ├─────────────────┼──────────────┼───────────────┼───────────┤
34            │collection       │              │               │           │
35            └─────────────────┴──────────────┴───────────────┴───────────┘
36
37       In a transaction, read concern and write concern are prohibited in opts
38       and  the  read preference must be primary or NULL.  See the example for
39       transactions and for the "distinct" command with opts.
40
41       reply is always initialized, and must be freed with bson_destroy().
42

PARAMETERS

44       · collection: A mongoc_collection_t.
45
46       · command: A bson_t containing the command specification.
47
48       · read_prefs: An optional mongoc_read_prefs_t.
49
50       · opts: A bson_t containing additional options.
51
52       · reply: A location for the resulting document.
53
54       · error: An optional location for a bson_error_t or NULL.
55
56       opts may be NULL or a BSON document with additional command options:
57
58       · readConcern:  Construct  a   mongoc_read_concern_t   and   use   mon‐
59         goc_read_concern_append  to  add  the  read  concern to opts. See the
60         example code for mongoc_client_read_command_with_opts.  Read  concern
61         requires MongoDB 3.2 or later, otherwise an error is returned.
62
63       · writeConcern:   Construct   a  mongoc_write_concern_t  and  use  mon‐
64         goc_write_concern_append to add the write concern to  opts.  See  the
65         example code for mongoc_client_write_command_with_opts.
66
67       · sessionId:  First,  construct  a  mongoc_client_session_t  with  mon‐
68         goc_client_start_session. You  can  begin  a  transaction  with  mon‐
69         goc_client_session_start_transaction, optionally with a mongoc_trans‐
70         action_opt_t that overrides the options  inherited  from  collection,
71         and  use mongoc_client_session_append to add the session to opts. See
72         the example code for mongoc_client_session_t.
73
74       · collation:  Configure  textual  comparisons.  See  Setting  Collation
75         Order,  and the MongoDB Manual entry on Collation. Collation requires
76         MongoDB 3.2 or later, otherwise an error is returned.
77
78       · serverId: To target a specific server, include  an  int32  "serverId"
79         field.  Obtain  the  id  by calling mongoc_client_select_server, then
80         mongoc_server_description_id on its return value.
81
82       Consult the MongoDB Manual entry on Database  Commands  for  each  com‐
83       mand's arguments.
84

ERRORS

86       Errors are propagated via the error parameter.
87

RETURNS

89       Returns  true  if successful. Returns false and sets error if there are
90       invalid arguments or a server or network error.
91
92       The reply is not parsed for a write concern timeout  or  write  concern
93       error.
94

EXAMPLE

96       See the example code for mongoc_client_read_command_with_opts.
