MongoDB\Driver\Server::executeQuery
Execute a database query on this server
説明
final public MongoDB\Driver\Cursor MongoDB\Driver\Server::executeQuery(string $namespace, MongoDB\Driver\Query $query, arrayMongoDB\Driver\ReadPreferencenull $options = null)
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.
