LaravelでSQL書いてみる

$sql = <<< SQL
            SELECT
                user_id,
                SEC_TO_TIME(
                    SUM(
                        TIME_TO_SEC(work_time) - TIME_TO_SEC('8:00:00')
                    )
                ) AS total_overtime
            FROM
                tb_user_work_time
            WHERE
                work_time > CAST('8:00:00' AS TIME)
            GROUP BY
                user_id
            HAVING
                total_overtime <= CAST('20:00:00' AS TIME);
SQL;
        $result = DB::select($sql);
