如何查找出以a表中主键为外键的所有表名及id

[whitechololate]

如何查找出以a表中主键为外键的所有表名及id，类似exec sp_fkeys 的效果，我需要的sql文，因为还要把选出来的表名和另外两个表中的字段列做比较，不能和它们重复

--表的外键约束

SELECT 外键表ID=b.fkeyid
,外键表名称=object_name(b.fkeyid)
,外键列ID=b.fkey
,外键列名=(SELECT name FROM syscolumns WHERE colid=b.fkey AND id=b.fkeyid)
,主键表ID=b.rkeyid
,主键表名=object_name(b.rkeyid)
,主键列ID=b.rkey
,主键列名=(SELECT name FROM syscolumns WHERE colid=b.rkey AND id=b.rkeyid)
,级联更新=ObjectProperty(a.id,'CnstIsUpdateCascade')
,级联删除=ObjectProperty(a.id,'CnstIsDeleteCascade')
FROM sysobjects a
join sysforeignkeys b on a.id=b.constid
join sysobjects c on a.parent_obj=c.id
where a.xtype='f' AND c.xtype='U'


--查询一个表的所有外键:

SELECT 主键列ID=b.rkey
,主键列名=(SELECT name FROM syscolumns WHERE colid=b.rkey AND id=b.rkeyid)
,外键表ID=b.fkeyid
,外键表名称=object_name(b.fkeyid)
,外键列ID=b.fkey
,外键列名=(SELECT name FROM syscolumns WHERE colid=b.fkey AND id=b.fkeyid)
,级联更新=ObjectProperty(a.id,'CnstIsUpdateCascade')
,级联删除=ObjectProperty(a.id,'CnstIsDeleteCascade')
FROM sysobjects a
join sysforeignkeys b on a.id=b.constid
join sysobjects c on a.parent_obj=c.id
where a.xtype='f' AND c.xtype='U'
and object_name(b.rkeyid)='titles'

[wgzaaa]

select object_name(rkeyid)表名,rkeyid id from sysforeignkeys where object_name(fkeyid)='a'

[bwu851]

select distinct object_name(fkeyid) as 表名, object_name(constid) as 外键名 
from sysreferences 
where rkeyid = object_id('a表') order by 1
