如何避免UNION on count（*）按值排序？

Question

此查询按select count（*）的值对结果进行排序。我不希望这种情况发生。我怎么能避免这个？我想按照它们在查询中编写的顺序显示它们。谢谢你的帮助。

这是一条查询：

(select count(*) as num_tweet from [TvPad2-dev].dbo.TWEET where REQUEST_ID = 7 
and CREATION_DATE>'2016-02-14 01:00:00.000' 
and CREATION_DATE<'2016-02-14 01:29:59.999' 
and text like '%arisa%') 

union 

(select count(*) as num_tweet from [TvPad2-dev].dbo.TWEET where REQUEST_ID = 7 
and CREATION_DATE>'2016-02-14 01:30:00.000' 
and CREATION_DATE<'2016-02-14 01:59:59.999' 
and text like '%arisa%') 

Answer 1

使用UNION ALL。

(select count(*) as num_tweet from [TvPad2-dev].dbo.TWEET where REQUEST_ID = 7 
and CREATION_DATE>'2016-02-14 01:00:00.000' 
and CREATION_DATE<'2016-02-14 01:29:59.999' 
and text like '%arisa%') 

union all

(select count(*) as num_tweet from [TvPad2-dev].dbo.TWEET where REQUEST_ID = 7 
and CREATION_DATE>'2016-02-14 01:30:00.000' 
and CREATION_DATE<'2016-02-14 01:59:59.999' 
and text like '%arisa%') 

Answer 2

UNION ALL会做到这一点。如果您将UNION更改为UNION ALL，您将无法获得排序结果。
