[Err] 1093 - You can't specify target table 'exam_arrange_list' for update in FROM clause

解决：

原来sql：

update exam_arrange_list  set IS_PASS_='及格' where ID_ in
(
select l.ID_ from exam_arrangement a
inner join  exam_arrange_list l on a.ID_=l.ARRANGEMENT_ID_
where  l.E_STATE_='已结束' and a.E_RESET_=0  and a.E_SEND_=1
)

修改后：

update exam_arrange_list  set IS_PASS_='及格' where ID_ in
(
SELECT r.ID_ from(
select l.ID_ from exam_arrangement a
inner join  exam_arrange_list l on a.ID_=l.ARRANGEMENT_ID_
where  l.E_STATE_='已结束' and a.E_RESET_=0  and a.E_SEND_=1
) r
)
