MongoDB\Driver\Manager::executeWriteCommand — Execute a database command that writes
$db, MongoDB\Driver\Command $command, ?array $options = null): MongoDB\Driver\CursorExecutes the command on the primary server.
This method will apply logic that is specific to commands that write (e.g.
» drop).
The default value for the "writeConcern" option will be
inferred from an active transaction (indicated by the
"session" option), followed by the
connection URI.
注意: This method is not intended to be used to execute » insert, » update, or » delete commands. Users are encouraged to use MongoDB\Driver\Manager::executeBulkWrite() for those operations.
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.
"session" option is used with an associated transaction in combination with a "readConcern" or "writeConcern" option."session" option is used in combination with an unacknowledged write concern.
| 版本 | 说明 |
