Question

我正在尝试这样做，但我在mySQL上遇到错误：

update ONE set (ONE.Names=TWO.New_Names)
from ONE 
join TWO on (ONE.Names=TWO.Old_Names);

Answer 1

update ONE 
join TWO on ONE.Names = TWO.Old_Names
set ONE.Names = TWO.New_Names

Answer 2

查看更新查询：

update one o
  join two t on ( o.names = t.old_names )
   set O.names = t.new_names;

join子句必须在query =＆gt;的开头写入 http://sqlfiddle.com/#!9/9f292c
