(mongodb >=1.0.0)

MongoDB\Driver\Server::executeQuery — Execute 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.

Parameter-Liste

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.

Rückgabewerte

Returns MongoDB\Driver\Cursor on success.

Fehler/Exceptions

Throws MongoDB\Driver\AuthenticationException if authentication is needed and fails
Throws MongoDB\Driver\ConnectionException if connection to the server fails for other then authentication reasons
Throws MongoDB\Driver\Exception\RuntimeException on other errors (e.g. invalid query operators).
