Select query, math and time

Question

Hi All;
I had Table as below:
UNIX_TIMESTAMP COUNT_VAL
1185416330 3
1185416355 2
1185416356 8
1185416357 2
1185416359 0
1185416361 1
1185416362 5
1185416363 7
1185416367 0.16
What I wanted to do is to get:
1. Average in intreval time like 5 sec
2. Highest value in interval time like 5 sec
For case 1:
The result should look like below:
UNIX_TIMESTAMP COUNT_VAL
1185416335 0.6
1185416340 0
1185416345 0
1185416350 0
1185416355 0.4
1185416360 2
1185416365 2.6
1185416370 0.03
For case 2:
The result should look like below:
UNIX_TIMESTAMP COUNT_VAL
1185416335 3
1185416340 0
1185416345 0
1185416350 0
1185416355 2
1185416356 8
1185416363 7
1185416367 0.16
The query should have select between UNIX_TIMESTAMP range.
So far I have no idea on how to do that. I really need help for above.
Please advise. Thank you very much.

Answer 1

Your Explanation is not clear atleast for me.
Why your o/p starts with ...35, even if there is an i/p value = ...30.Why there is no
o/p curresponding to ...60? (Second case)
How is your range Defined..?From o/p it seems to be 26-30,31-35,36-40...(But no ..30 appears)
Anyhow below sample code may give you a start .
SQL> select * from test;
        TS        CNT
        30          3
        55          2
        56          8
        57          2
SQL>  with t as
  2   (select min(ts) minimum,max(ts) maximum
  3    from test)
  4   select rn ts,sum(nvl(cnt,0))/5 avrg
  5   from test,(select minimum+(level-1)*5 rn
  6              from t
  7              connect by level <= ceil((maximum-minimum)/5)+1) t1
  8   where test.ts(+) between t1.rn-4 and t1.rn
  9   group by rn
10   order by 1;
        TS       AVRG
        30         .6
        35          0
        40          0
        45          0
        50          0
        55         .4
        60          2
7 rows selected.
