/***********************************************************************************************
nf_ChangeObjectOwner

实现功能：    将Sql Server对象的当前拥有者更改成目标拥有者
**** 使用本代码前请备份数据库！
**** 所带来的安全问题，与俺家的驴子无关！
**** 欢迎斧头劈我，劈死偶有奖！
调用方法：    Exec nf_ChangeObjectOwner @current_Owner,@target_Owner,@modify_Type

输入参数：    @current_Owner nvarchar(255)    --对象的当前拥有者
        @target_Owner nvarchar(255)    --对象的目标拥有者
        @modify_Type int        --0为默认，更改表的拥有者；1为视图和存储过程
输出参数：    RETURN值        = -1        --操作对象为0，操作对象不存在
                = -2        --操作失败，可能对象被锁定
                = 0(默认值)    --操作成功，打印更改对象数目@object_Num
        @object_Num            --SQL 打印值，返回更改成功的对象数目
