Question

我有两张桌子（tblnews和tblarticles）。我想按日期一起显示最新的文章和新闻。例如，这两个表中的前10名并显示标题。但我不知道应该如何使用这两个选项编写下面的代码，但它有一些错误。

         (select top (10)(([NewsId]) as id,([NewsTitle]) as title,([NewsDate]) as date,[NewsActive]) from [tblnews] 
    where ([NewsActive]='true')) Order by date Desc)
     UNION ALL
     (Select Top(10)([ArticleId] as id,[ArticleTitle] as title ,
         [ArticleDate] as date, [ArticleActive])
 From [tblarticle] where [ArticleActive]='true'
 order by date DESC )order by date DESC

Answer 1

所有括号是什么？删除它们

select * from
(
    (select top (10) [NewsId] as id, [NewsTitle] as title, [NewsDate] as date, [NewsActive]
    from [tblnews] 
    where [NewsActive]='true' 
    Order by date Desc)
    UNION ALL
    (Select Top(10) [ArticleId], [ArticleTitle], [ArticleDate], [ArticleActive]
    From [tblarticle] 
    where [ArticleActive]='true'
    order by date DESC )
) tmp
order by date DESC

sql从没有内连接的两个表中选择
