MySQL的聯盟返回BLOB

Question

我想聯盟2代表具有相同的字段（具有相同的VARCHAR大小/ INT大小等）

但在瀏覽器中，我得到的斑點......

select * from 
(
select * from (
SELECT media.id,ifnull(wasRead,0) as wasRead 
,teamid,newsDate,itemid 
,var1,var2,var3,var4,title,content 
,ifnull(optionSel,0) as optionSel,0 as itemType 
FROM media 
left join mediaList on mediaList.id = media.itemId 
where teamid = '1') as media 

union all 

select * from (
select managerNews.id,ifnull(wasRead,0) as wasRead 
,teamid,newsDate,itemid 
,var1,var2,var3,var4,title,content 
,ifnull(optionSel,0) as optionSel,0 as itemType 
from managerNews 
left join managerNewsList on managerNewsList.id = managerNews.itemId 
where teamid = 1) as managerNews 
) as merged 

order by newsDate desc 
limit 50 

我只是不知道該怎麼做。

在此先感謝。

Answer 1

那麼，在該行有不同的排序規則。太奇怪了，我錯誤地看到了，但終於解決了。

感謝:-)
