SQL 存储过程 分组后查找重复的列
很急，求大神！
目前有CTYPE,CCOMMEN,CFIELD,CFIELDID,COFFSE这几烈数据
检查数据是否合法，即以CTYPE分组，在每组CTYPE中如果CCOMMEN相同则CFIELD,CFIELDID,COFFSET的值必须也相同。也就是要查找出不合法的行。最好用firebird数据库存储过程语法描述，用其他语法也可以。 存储过程? SQL 数据库
[解决办法]
我假设你CTYPE CCOMMEN这两个字段是主键，如果主键是ctype那么on后面只需要一个关联条件即可

--> 测试数据：[huang]
if object_id('[huang]') is not null drop table [huang]
go
create table [huang]([CTYPE] int,[CCOMMEN] int,[CFIELD] int,[CFIELDID] int,[COFFSE] int)
insert [huang]
select 1,1,1,1,1
UNION ALL
select 1,1,1,1,1
UNION ALL
select 2,1,1,1,1
UNION ALL
select 1,2,1,1,1
--------------开始查询--------------------------
SELECT DISTINCT * FROM [huang] a
WHERE EXISTS (SELECT 1 FROM (
select [CTYPE],[CCOMMEN],ROW_NUMBER()OVER(PARTITION BY CTYPE,CCOMMEN,CFIELD,CFIELDID,COFFSE ORDER BY CTYPE,CCOMMEN)[count]
from [huang])b WHERE a.[CTYPE]=b.[CTYPE] AND a.[CCOMMEN]=b.[CCOMMEN] AND b.[count]>1)
----------------结果----------------------------
/*
CTYPE CCOMMEN CFIELD CFIELDID COFFSE
----------- ----------- ----------- ----------- -----------
1 1 1 1 1
*/
select * from tb t
where exists(select * from tb
where CTYPE=t.CTYPE and CCOMMEN=t.CCOMMEN
and (CFIELD<>t.CFIELD or CFIELDID<>t.CFIELDID or COFFSE<>t.COFFSE))
