MongoDB\Driver\Server::executeWriteCommand — Execute a database command that writes on this server
$db
, MongoDB\Driver\Command $command
[, array $options = array()
] )Executes the command on this server.
This method will apply logic that is specific to commands that write (e.g. » drop) and take the MongoDB server version into account. The "writeConcern" option will default to the corresponding value from the MongoDB Connection URI.
db (string)The name of the database on which to execute the command.
command (MongoDB\Driver\Command)The command to execute.
options
| Option | Type | Description |
|---|---|---|
| session | MongoDB\Driver\Session |
A session to associate with the operation. |
| writeConcern | MongoDB\Driver\WriteConcern |
A write concern to apply to the operation. |
If you are using a "session" which has a transaction in progress, you cannot specify a "readConcern" or "writeConcern" option. This will result in an MongoDB\Driver\Exception\InvalidArgumentException being thrown. Instead, you should set these two options when you create the transaction with MongoDB\Driver\Session::startTransaction().
Returns MongoDB\Driver\Cursor on success.
| Version | Description |
|---|---|
| 1.4.4 | MongoDB\Driver\Exception\InvalidArgumentException will be thrown if the "session" option is used in combination with an unacknowledged write concern. |
Note: It is the caller's responsibility to ensure that the server is capable of executing the write operation. For example, executing a write operation on a secondary (excluding its "local" database) will fail.
