感兴趣的小伙伴,下面一起跟随编程之家 jb51.cc的小编两巴掌来看看吧!
1/准备测试数据
---------------------------------------------------------------------------------
create table t1(
c1 integer,
c2 integer,
c3 integer
);
insert into t1 values(1,2,3)
insert into t1 values(1,8,4)
insert into t1 values(1,4,4)
insert into t1 values(1,5)
insert into t1 values(1,5,5)
insert into t1 values(2,3)
insert into t1 values(2,4)
insert into t1 values(2,4)
insert into t1 values(2,5)
2/查看排名
---------------------------------------------------------------------------------
A/单记录排名
select c1,c3,
(select count( c3)+1 from t1 a where a.c3>b.c3
and a.c1=b.c1 and a.c1 =1
) order_num
from t1 b
where c1 =1
order by c1,c3
c1 c3 order_num
----------- ----------- ----------------------
1 3 5
1 4 3
1 4 3
1 5 1
1 5 1
B/多记录排名
select c1,c2,
(select count( c3)+1 from t1 a where a.c3>b.c3
and a.c1=b.c1
) order_num
from t1 b
order by c1,c3
c1 c2 c3 order_num
----------- ----------- ----------- ----------------------
1 2 3 5
1 8 4 3
1 4 4 3
1 4 5 1
1 5 5 1
