如何查询同一个表中两个字段分别相同的数据

[jlds0123]

表X
id B C D

0 2 3 4

1 6 7 8

2 2 8 4


第一条和第四条数据 B、D字段值相同，如何将其查出来 （详细说明下，谢谢）

[sxn19811006]

select a.B,a.D from x a, x b where a.B=b.B and a.D=b.D

[中国风]

select * from table1 t where (select count(1) from table1 where b=t.b and d=b.d)>1

[flairsky]

select a.* from x a inner join x b on a.b = b.b and a.d=b.d

自连接、同一个表建两个别名

[liyan93834183]

select * from x where b in (select b from x) and d in (select d from x)

[水族杰纶]

declare @t table(id int, B int, C int, D int)
insert @t select 0, 2, 3, 4
insert @t select 1, 6, 7, 8
insert @t select 2, 2, 8, 4
select * from @t t where exists(select 1 from @t where B=t.B and D=t.D and ID<>t.ID )

[Humming-bird]

select * from test a, test b where a.B=b.B and a.D=b.D and a.ID<>b.ID

[sp4]

select * from table_Pqs Pqs 
 where Exists(select 1 from table_Pqs 
 where b=Pqs.b and d=Pqs.d And id<>table_Pqs.id)

[sp4]

--如果想直接排列出顺序，便于查看就加上排序
select * from table_Pqs Pqs 
 where Exists(select 1 from table_Pqs 
 where b=Pqs.b and d=Pqs.d And id<>table_Pqs.id)
 Order By b,d

--如果作为一条记录显示 那就如上用inner join方式，但就结果而言应该是反复出现了2次

select a.B,a.D from x a, x b where a.B=b.B and a.D=b.D
