anyway, in pure sql this should work:Well, it is not pure sql solution. It is SQL*Plus solution. BREAK, COMPUTE are SQL*PLus, not SQL commands. Also, your code will group rows 1 - 10, 11 - 100, 101 - 1000 rather than each 10 rows. Just add one row to sample:
SQL> SET PAGES 0
SQL> COL grp NOPRINT
SQL> BREAK ON grp SKIP 1
SQL> COMPUTE SUM OF value ON grp
SQL> WITH t AS (
  2  SELECT 100 value  FROM dual UNION ALL
  3  SELECT 200   FROM dual UNION ALL
  4  SELECT 300   FROM dual UNION ALL
  5  SELECT 400   FROM dual UNION ALL
  6  SELECT 100   FROM dual UNION ALL
  7  SELECT 50    FROM dual UNION ALL
