UNION查询 - 显示订单查询的结果

Question

示例 -

select * from discussion where title like '%india%' 
UNION 
select * from discussion where title like '%Australia%'

它按照讨论ID的顺序显示结果两种类型的结果

我想首先显示印度结果然后显示澳大利亚的结果,我不能使用Option ALl,因为我还需要删除重复的行.

应该做什么？

Answer 1

您可以添加要订购的列

select *, 1 as ORD from discussion where title like '%india%' 
UNION 
select *, 2 as ORD from discussion where title like '%Australia%'

order by ORD

由于与ORD问题的重复,我正在考虑一种,或许,更优雅的方式来实现这一点

Select * from discussion
where title like '%india%' or title like '%Australia%'
order by (case when title like '%india%'then 1 else 2 end)
