AS ?x)\r\n  FILTER(fn:stderr(CONCAT(\"Obtained \", ?x, \" from input \", ?a, ?b, ?c))\r\n}  \r\n```\r\nSo we should create a filter function that always yields true but as a side effect prints out its argument.\r\n\r\nNote: Select queries can already be used for debug output: Their output goes to STDERR - whereas CONSTRUCT queries go to STDOUT - so only the latter produces data output."}}
