Hi,
i need some help on a query.
I've this table :
create table t (
customer number(5),
time date,
status varchar2(1)
)
/
insert into t values (1,to_date('20030101','yyyymmdd'),1); insert into t values (1,to_date('20030121','yyyymmdd'),0); insert into t values (1,to_date('20030803','yyyymmdd'),1); insert into t values (1,to_date('20030909','yyyymmdd'),1); insert into t values (1,to_date('20031201','yyyymmdd'),0);
What i want is this output :
customer status begin_ end_ 1 1 01/01/03 21/01/03 1 0 21/01/03 03/08/03 1 1 03/08/03 01/12/03 1 0 01/12/03
on a windows 2000 platform EE 8.1.7, i write this query :
select customer,
status, time begin_, lead(time) over (partition by customer order by time) end_from t
order by customer, time
/
CUSTOMER S BEGIN_ END_
--------- - -------- --------
1 1 01/01/03 21/01/03 1 0 21/01/03 03/08/03 1 1 03/08/03 09/09/03 1 1 09/09/03 01/12/03 1 0 01/12/03
but this is not exactly what i search.
Can someone help me ?
Thanks in advance
