Merge 当子查询的表达式值大于1时不允许！在SQLServer2008中

首先为我的英语感到抱歉

我正在尝试将记录插入表中。。。记录是项目表和临时表之间的差异

我的密码是

insert into pro_updatelog 
   select *, @user_n, GETDATE() 
   from pro 
   where cod = (select cod 
                from (SELECT * FROM pro 
                      EXCEPT 
                      SELECT * FROM temp 
                      UNION ALL 
                      SELECT * FROM temp 
                      EXCEPT 
                      SELECT * FROM pro) as T1);

然后合并临时表和原始表

不知道我该怎么办

我想要的是，如果原始表和临时表之间存在任何差异，请将原始值记录到pro_updatelog表中。。。最好只在表中记录更新后的值，但是否记录整行并不重要，但我希望记录更新前的原始值

任何想法都将不胜感激

谢谢

通过使用合并，我成功地做到了这一点。。。无论如何，完成存储过程需要更长的时间，但它可以按我的要求执行->

insert into pro_updatelog
    select * , @user_n, GETDATE() from
        (SELECT * FROM pro
        EXCEPT
        SELECT * FROM temp
        UNION ALL
        SELECT * FROM temp
        EXCEPT
        SELECT * FROM pro) as T1;
merge pro_updatelog as tar
    using pro as sor
    on (tar.cod = sor.cod)
    when matched then
        update set
