Time Series in Discoverer.

Question

Hi, wondering if anybody knows how I can use time series functionality in Discoverer3.1 and 3i?

Answer 1

Thanks a lot for the responses.
I looked at the 11g Pivot operator and is altogether a new feature compared to the Time series of 8i.
I would like to explain with an example.
1) The following query creates a table named stockdemo_calendars and defines a calendar
named BusinessDays. The BusinessDays calendar includes Mondays through Fridays,
but excludes 28-Nov-1996 and 25-Dec-1996. Explanatory notes follow the example.
CREATE TABLE stockdemo_calendars of ORDSYS.ORDTCalendar (
name CONSTRAINT calkey PRIMARY KEY);
INSERT INTO stockdemo_calendars VALUES(
ORDSYS.ORDTCalendar(
0
’BusinessDays’,
4,
ORDSYS.ORDTPattern(
ORDSYS.ORDTPatternBits(0,1,1,1,1,1,0),
TO_DATE(’01-JAN-1995’,’DD-MON-YYYY’)),
TO_DATE(’01-JAN-1990’,’DD-MON-YYYY’),
TO_DATE(’01-JAN-2001’,’DD-MON-YYYY’),
ORDSYS.ORDTExceptions(TO_DATE(’28-NOV-1996’,’DD-MON-YYYY’),
TO_DATE(’25-DEC-1996’,’DD-MON-YYYY’)),
ORDSYS.ORDTExceptions()
-------------- How can I create such calendars in 11g?
2) For example, the following statement returns the last closing prices for stock
SAMCO for the months of October, November, and December of 1996:
select * from the
(select cast(ORDSYS.TimeSeries.ExtractTable(
ORDSYS.TimeSeries.ScaleupLast(
ts.close,
sc.calendar,
to_date(’01-OCT-1996’,’DD-MON-YYYY’),
to_date(’01-JAN-1997’,’DD-MON-YYYY’)
) as ORDSYS.ORDTNumTab)
from tsdev.stockdemo_ts ts, tsdev.scale sc
where ts.ticker=’SAMCO’ and
sc.name =’MONTHLY’);
This example might produce the following output:
TSTAMP VALUE
01-OCT-96 42.375
01-NOV-96 38.25
01-DEC-96 39.75
3 rows selected.
--------------------- How can I get the above ouput without Time series functions and calendars in Oracle 11g?
