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

SQL code

-----------------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'
