按照规则重命名所有外键名称（续）

刚才看了看系统表的相关信息，其实还是有很多方法的，呵呵！

--
SELECT    b.NAME AS fkName, 
        c.NAME AS fkTable, 
        e.NAME AS fkColName, 
        d.NAME AS pkTable, 
        f.NAME AS pkColName, 
        a.*
FROM    sysreferences AS a
    JOIN sysobjects AS b ON a.constid = b.id 
    JOIN sysobjects AS c ON a.fkeyid = c.id
    JOIN sysobjects AS d ON a.rkeyid = d.id
    JOIN syscolumns AS e ON a.fkeyid = e.id AND e.colid = a.fkey1
    JOIN syscolumns AS f ON a.rkeyid = f.id AND f.colid = a.rkey1
WHERE b.type = 'F'

对上面的查询语句再加以游标处理，也可以实现批量重命名外键。

通过这件事也让我认识到加深对系统表理解的重要性。
