Hi All,
I have the following table and pivot query:
CREATE TABLE TEST_PIV (
YEAR NUMBER,
PROJECT_SECTOR_ID NUMBER(2, 0) NOT NULL,
NETLOAN NUMBER);
INSERT INTO TEST_PIV(YEAR, PROJECT_SECTOR_ID, NETLOAN) VALUES

pivot
(
sum(netloan)
for PROJECT_SECTOR_ID in (1,2,3,4,5,6,7,8)
)
order by year;
However instead of displaying each year (1975, 1976, 1977... etc.) I need to group the year column so it shows every 5 years together except for the last five years (they should appear separately). so I need the year column to show:
1975-1979
1980-1984
1985-1989
...
2010-2014
2015-2015 (or just 2015)
2016
2017
2018
2019
2020
Thanks,
Ferro

Years in your test case start with 1975 so it isn't clear you you want to group years into group ending 0 to 4 and 5 to 9 regardless of oldest year in the table or group years in groups of five years starting with the oldest year in the table. For former use:
with t as (
select (year - mod(year,5)) || ' - ' || (year - mod(year,5) + 4) years,
project_sector_id,
netloan
from test_piv
)
select *
from t
pivot(
sum(netloan)
for project_sector_id in (1,2,3,4,5,6,7,8)
)
order by years
/

For latter:

project_sector_id,

Ah, I missed last 5 years part. Again, not clear if last five years based on today or on table data. I'll assume based on today:
with t as (
select case
when year >= to_number(to_char(sysdate,'yyyy')) - 4 then to_char(year)
else (year - mod(year,5)) || ' - ' || (year - mod(year,5) + 4)
end years,
project_sector_id,
netloan
from test_piv
)
select *
from t
pivot(
sum(netloan)
for project_sector_id in (1,2,3,4,5,6,7,8)
)
order by years
/

Ah, ending year should be adjusted, otherwise:

As you can see, 2015 - 2019 is wrong. Adjusted query:

Post INSERT statement with data in these years we could search at our side. ![Wink](/forum/images/smiley_icons/icon_wink.gif)
And clarify your specification as Solomon pointed.
Are the 5 years interval always 0-4 and 5-9, or 5 years interval before the current year (that is for 2021, 1-5 and 6-0, for 2022 2-6, 7-1)? Or 5 years starting from the first year in the data (that is if first year is 1974 then 4-8, 9-3, if it is 1973 3-7 and 8-2)?

Dear Michel,
Thanks for your follow up.
The data can start at any year (in fact the actual data starts in 1974 which is handled perfectly by last example which adds 1970-1974 interval. So it is safe to keep it this way for older years. The issue is in handling the last years as the repetition leads to confusing results (having an internal for 2015-2019, then having the years 2016,...,2019 separately).
The table with the new data:
drop table TEST_PIV;
CREATE TABLE TEST_PIV (
YEAR NUMBER,
PROJECT_SECTOR_ID NUMBER(2, 0) NOT NULL,
NETLOAN NUMBER);
INSERT INTO TEST_PIV(YEAR, PROJECT_SECTOR_ID, NETLOAN) VALUES
(1993, 7, 8);
INSERT INTO TEST_PIV(YEAR, PROJECT_SECTOR_ID, NETLOAN) VALUES
(1993, 5, 29.76);
INSERT INTO TEST_PIV(YEAR, PROJECT_SECTOR_ID, NETLOAN) VALUES

@SY, your last example runs very fast in large data and is completely dynamic with future years, however if the output data contain years 2015, 2016, 2017, 2018, 2019, 2020; the result will include:
2015-2019 (holding only the data for 2015 followed by each year separately)
2016
2017
2018
2019
2020
I am trying to figure out how to add an extra condition that doesnt have hard wiring the year 2015 and could get me (2015-2015) in case the last group has only one year or less than 5 years.
Thanks,
Ferro
Not sure I understand why would you want to show 2015-2019 if it is holding only the data for 2015? My one before last reply does this.
So you want to list 2016, 2017, 2018, 2019 and 2020 even though they have no data? If so:
with t1 as (
select *
from test_piv
union all
select to_number(to_char(sysdate,'yyyy')) + 1 - level,
1,
null
from dual
connect by level <= 6
),
t2 as (
select case
when year > to_number(to_char(sysdate,'yyyy')) - 5 then to_char(year)
else (year - mod(year,5)) || ' - ' || least(to_number(to_char(sysdate,'yyyy')) - 5,year - mod(year,5) + 4)
end years,
project_sector_id,
netloan
from t1
)
select *
from t2
pivot(
sum(netloan)
for project_sector_id in (1,2,3,4,5,6,7,8)
)
order by years

The queries in my last 2 posts are the same one for the 2 set of data you posted.
I generate a calendar to have all intervals and years from the first year in your data to current year even if you have no data for this interval or year.
