MongoDB\Driver\Server::executeQuery

(mongodb >=1.0.0)

MongoDB\Driver\Server::executeQueryExecute a database query on this server

Beschreibung

final public MongoDB\Driver\Cursor MongoDB\Driver\Server::executeQuery ( string $namespace , MongoDB\Driver\Query $query [, MongoDB\Driver\ReadPreference $readPreference ] )

Executes query on this server.

Hinweis:

The readPreference parameter does not control the server to which the driver issues the query; the query will always be executed on this server object. Instead, it may be used when issuing the command to a secondary (from a replica set connection, not standalone) or mongos node to ensure that the driver sets the wire protocol accordingly or adds the read preference to the query document, respectively.

namespace

A fully qualified namespace (databaseName.collectionName)

query (MongoDB\Driver\Query)

The MongoDB\Driver\Query to execute.

readPreference

Optionally, a MongoDB\Driver\ReadPreference to route the command to. If none given, defaults to the Read Preferences set by the MongoDB Connection URI.
