尝试更新多行会引发512错误

Question

有人可以为下面的代码提供替代解决方案吗？尝试更新多个记录时收到512错误。

update ActiveParty
set rmname = (select  CONCAT(rmname,rmadr1)
                from ActiveParty
                 where RMADR1 like ('%C/O%') or RMADR1 like ('%Attention%') or 
                 RMADR1 LIKE '%!%%' escape '!')
where RMADR1 in (select  RMADR1
                    from ActiveParty
                        where RMADR1 like ('%C/O%') or RMADR1 like 
                   ('%Attention%') or RMADR1 LIKE '%!%%' escape '!');

Answer 1

您可以更简单地将其重写为：

update ActiveParty
set rmname = CONCAT(rmname,rmadr1)
where RMADR1 like ('%C/O%') 
    or RMADR1 like ('%Attention%') 
    or RMADR1 LIKE '%!%%' escape '!'
