关于like的排序问题,真心求助
场景:
一个文章表(T_Article),里面有两个字段,标题(title)和内容(content)
用户输入一个keyword,从文章表的title和content中搜索记录

SQL语句如下:
SELECT * FROM T_Article WHERE title LIKE '%keyword%' OR content LIKE '%keyword%';

问题来了,我现在需要对结果集进行排序,需要先把标题匹配的记录放在前面,内容匹配但是标题不匹配的记录放在后面,
请问SQL语句怎么写,或者有什么解决方法。

分数不多,真心求助

------解决方案--------------------
select *,1 as aa from tb where name like '%1%'
union
select *,2 as aa from tb where pay like '%1%'
order by aa


------解决方案--------------------
SQL code

--对结果再进行一次title LIKE '%keyword%'就可以了

;with cte as
(
    SELECT * FROM T_Article WHERE title LIKE '%keyword%' OR content LIKE '%keyword%'
)
select * from cte
WHERE title LIKE '%keyword%'

--或

select * from 
(
    SELECT * FROM T_Article WHERE title LIKE '%keyword%' OR content LIKE '%keyword%'
) t
WHERE t.title LIKE '%keyword%'

------解决方案--------------------
SQL code

select * from
(
   SELECT *,xh=1 FROM T_Article WHERE title LIKE '%keyword%'
   union all
   select *,xh=2 FROM T_Article WHERE content LIKE '%keyword%'
)a
order by xh

------解决方案--------------------
SQL code
SELECT * FROM T_Article 
WHERE title LIKE '%keyword%' OR content LIKE '%keyword%'
order by case when  title LIKE '%keyword%' then 0 else 1 end
