求关于ＭＹＳＱＬ的一句简单语句．．．
update   tGroup   set   cID=iAutoID   where   iAutoID   =(select   max(iAutoID)   from   tGroup)   ;

以上本来是ＭＳＳＱＬ里的正确语句，
在ＭＹＳＱＬ中运行报错？请问应该怎么写？

------解决方案--------------------
update tGroup set cID=iAutoID where iAutoID in (select idt from (select max(iAutoID) as idt from tGroup) as t)
