MongoDB\Driver\Server::executeQuery — Execute a database query on this server
Описание
$namespace
, MongoDB\Driver\Query $query
[, MongoDB\Driver\ReadPreference $readPreference
] )
Executes query on this server.
Замечание:
The
readPreferenceparameter 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(string) -
A fully qualified namespace (e.g. "databaseName.collectionName").
