为什么这个不行？我试图从前面的问题中得出一个答案，但在这里它给了我错误。
mysql错误

create trigger logsupdate before update on users
for each row 
begin
  if new.pJailed <> old.pJailed then
    set new.jailtime = now();
     if new.pVIP <> old.pVIP then
    set new.TM2 = now();
         if new.pAdminLevel <> old.pAdminLevel then
    set new.TM3 = now();
  end if;
end;
