MongoDB\Driver\Server::executeQuery

(mongodb >=1.0.0)

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

Descrierea

final public MongoDB\Driver\Server::executeQuery ( string $namespace , MongoDB\Driver\Query $query , array $options = array() ) : MongoDB\Driver\Cursor

Executes the query on this server.

Notă: The "readPreference" option does not control the server to which the driver issues the operation; it will always be executed on this server object. Instead, it may be used when issuing the operation 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 operation, respectively.
