MongoDB\Driver\Server::executeQuery — Execute a database query on this server
$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.
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.
Returns MongoDB\Driver\Cursor on success.
