MongoDB\Driver\Server::executeQuery
(mongodb >=1.0.0)
MongoDB\Driver\Server::executeQuery — Execute a database query on this server
説明
$namespace, MongoDB\Driver\Query $query, array|MongoDB\Driver\ReadPreference|null $options = null): MongoDB\Driver\CursorExecutes the query on this server.
Default values for the "readPreference" option and Query's
"readConcern" option will be inferred from an active
transaction (indicated by the "session" option), followed
by the connection URI.
注意: 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.
