联合查询，显示结果写入

Question

例子 -

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

它显示我在讨论ID的顺序结果混合结果

我想显示印度的两个typse的成绩放在第一位，然后澳大利亚的结果我不能使用Option ALl，因为我也需要删除重复的行。

应该做什么？

Answer 1

你可以添加一列命令的

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

order by ORD

考虑一个，也许更优雅的方式来实现这个

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

Answer 2

尝试：

SELECT * FROM 
(
    select 1 OrderNo, d.* from discussion d where title like '%india%' 
    UNION 
    select 2 OrderNo, d.* from discussion d where title like '%Australia%' 
) 
ORder by OrderNo 

Answer 3

select * from 
(
select * from discussion where title like '%india%' 
UNION 
select * from discussion where title like '%Australia%' 
) 
ORDER BY title DESC 
;
