MongoDB\Driver\Server::executeWriteCommand

(mongodb >=1.4.0)

MongoDB\Driver\Server::executeWriteCommandExecute a database command that writes on this server


说明

final public MongoDB\Driver\Server::executeWriteCommand ( string $db , MongoDB\Driver\Command $command [, array $options = array() ] ) : MongoDB\Driver\Cursor

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.

Note:

This method is not intended to be used to execute » insert, » update, or » delete commands. Users are encouraged to use MongoDB\Driver\Server::executeBulkWrite() for those commands.

参数

db (string)

The name of the database on which to execute the command.

command (MongoDB\Driver\Command)

The command to execute.

options
{| |+ 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.

|}

Warning

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().


返回值

Returns MongoDB\Driver\Cursor on success.


错误/异常


更新日志

版本 说明
PECL mongodb 1.4.4 MongoDB\Driver\Exception\InvalidArgumentException

will be thrown if the "session" option is used in combination with an unacknowledged write concern.


注释

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.
