[slighty off topic] Until puzzle forum arrives, here's a trick I often used to get a quick look of data.
If you want a graph of the ratio of each salary to the greatest one:
SQL> column sal_graph format a10
SQL> column ratio_to_max format a52 heading " Ratio to max salary (*=2% of max)"
SQL> select ename, sal, lpad( '*', trunc(sal/1000), '*') sal_graph,
  2         rpad(rpad('|',1+round(50*sal/max(sal) over ()),'*'),51)||'|' ratio_to_max
  3  from emp
  4  /
ENAME             SAL SAL_GRAPH   Ratio to max salary (*=2% of max)
---------- ---------- ---------- ----------------------------------------------------

Geez, first you complain about doing the OP's homework, then you help them get bonus points. You crack me up sometimes Michel! Laughing
