T-SQL中找出一個表的全部外鍵關聯表

二種方法(下例中表名爲T_Work)

1.SQL查詢系統表 

SELECT 主鍵列ID=b.rkey
    ,主鍵列名=(SELECT name FROM syscolumns WHERE colid=b.rkey AND id=b.rkeyid)
    ,外鍵表ID=b.fkeyid
    ,外鍵表名稱=object_name(b.fkeyid)
    ,外鍵列ID=b.fkey
    ,外鍵列名=(SELECT name FROM syscolumns WHERE colid=b.fkey AND id=b.fkeyid)
    ,級聯更新=ObjectProperty(a.id,'CnstIsUpdateCascade')
    ,級聯刪除=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)='T_Work'

 

2.系統存儲過程

exec sp_helpconstraint T_Work
