I have to write a query based on count of transactions per month and year, basically i want to show months as columns and year / transaction type as rows.
create table vouch_count(vouch_code varchar2(12),vouch_year_mth varchar2(12),vouch_count number);
insert into vouch_count(vouch_code,vouch_year_mth,vouch_count) values ('BKP','201801',40);
insert into vouch_count(vouch_code,vouch_year_mth,vouch_count) values ('BKC','201802',50);
insert into vouch_count(vouch_code,vouch_year_mth,vouch_count) values ('BKP','201901',100);
insert into vouch_count(vouch_code,vouch_year_mth,vouch_count) values ('BKC','201901',90) ;
--I wrote this query
SELECT * FROM (
SELECT VOUCH_CODE,VOUCH_YEAR_MTH,VOUCH_COUNT
FROM VOUCH_COUNT
)
PIVOT ( sum(VOUCH_count)
FOR voucH_year_mTH IN ('201801','201802'))
--output is as follows.
201801 201802
BKP 40
BKC 50
-- i want the output to be as
01 02
BKP 2018 40 50
2019
BKC 2018 100 90
2019

11 pivot (sum(vouch_count) for mnth in ('01','02','03','04','05','06','07','08','09','10','11','12'))
