MongoDB\Driver\Server::executeQuery — Execute a database query on this server
说明
$namespace ,
MongoDB\Driver\Query $query [,
array $options = array() ] ) :
MongoDB\Driver\Cursor
Executes the query on this server.
Note: 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.
