MongoDB\Driver\Server::executeQuery

(mongodb >=1.0.0)

MongoDB\Driver\Server::executeQuery — Execute a database query on this server

Descrição

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

Executes query on this server.

Nota:
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.

Parâmetros

namespace (string): Um namespace completo (por exemplo "databaseName.collectionName").
query (MongoDB\Driver\Query): A MongoDB\Driver\Query a executar.
readPreference (MongoDB\Driver\ReadPreference): Um MongoDB\Driver\ReadPreference para rotear o comando, opcional. Se nenhum informado, o padrão para Read Preferences é configurado no URI de Conexão do MongoDB.

Valor Retornado

Retorna MongoDB\Driver\Cursor no sucesso.

Erros

Lança MongoDB\Driver\Exception\InvalidArgumentException no caso de erros ao interpretar parâmetros.
Lança MongoDB\Driver\Exception\ConnectionException se a conexão com o servidor falhar (por razões outras que autenticação).
Lança MongoDB\Driver\Exception\AuthenticationException se a autenticação é necessária e falha.
Throws MongoDB\Driver\Exception\RuntimeException on other errors (e.g. invalid query operators).
