PHP Manual :: MongoDB\Driver\Server::executeQuery



MongoDB\Driver\Server::executeCommand || MongoDB\Driver\Server::getHost || MongoDB\Driver\Server || PHP Manual

(mongodb >=1.0.0)

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

Description

final public MongoDB\Driver\Cursor MongoDB\Driver\Server::executeQuery ( string $namespace , MongoDB\Driver\Query $query [, MongoDB\Driver\ReadPreference $readPreference ] )

Executes query on this server.

Note:

The readPreference parameter 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.

Parameters

namespace (string)

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

query (MongoDB\Driver\Query)

The MongoDB\Driver\Query to execute.

readPreference (MongoDB\Driver\ReadPreference)

Optionally, a MongoDB\Driver\ReadPreference to select the server for this operation. If none is given, the read preference from the MongoDB Connection URI will be used.

Return Values

Returns MongoDB\Driver\Cursor on success.
