如何获取SQLSERVER所有表的外键关系参数-MS-SQLServer/基础类

通过下列查询可得到关系的表名和列名
select object_name(A.parent_obj) as 表名 
 ,col_name(A.parent_obj,B.fkey) as 列名  
 ,object_name(B.rkeyid) as 引用表名 
 ,col_name(B.rkeyid,B.rkey) as 引用列名 
from sysobjects A 
join sysforeignkeys B on A.id=B.constid
我想知道更细的关系设置情况,如何用SELECT获取如下具体的参数:
INSERT 和 UPDATE 规范中的更新规则和删除规则参数(如:不执行任何操作/级联/设置 Null/设置默认值)
强制外键约束的参数为是或否
强制用于复制的参数为是或否

     -----------------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)='tb'
