Oracle 按相同数据连续统计
create table test(
id number(20),
val number(20)
)
insert into test values(1,5);
insert into test values(2,10);
insert into test values(3,10);
insert into test values(4,10);
insert into test values(5,6);
insert into test values(6,6);
insert into test values(7,10);
insert into test values(8,10);
SELECT val,COUNT(*) FROM
(
SELECT ID,val,
row_number() OVER(ORDER BY ID)-row_number() OVER(PARTITION BY val ORDER BY ID) x
FROM TEST
)
GROUP BY val,x
ORDER BY MIN(ID);
