MongoDB\Driver\Server::executeQuery

(mongodb >=1.0.0)

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

说明

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

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.

参数

namespace (string)

A fully qualified namespace (e.g. "databaseName.collectionName").

query (MongoDB\Driver\Query)

The query to execute.

options

Option Type Description
