sql - 如何编写基于排名的选择查询？

Question

我有一张桌子

表格1

id   city    projects       Rank
----------------------------------
1    che        p2           2
2    bang       p1           1
3    che        p4           1
4    bang       p3           2
5    bang       p5           3
6    gur        p6           1
7    gur        p7           2

根据排名我想选择我想要的城市和项目

   bang       p1            1
    che        p4           1
    gur        p6           1
    che        p2           2
    bang       p3           2
    gur        p7           2
    bang       p5           3

select * from table1 where Rank = ?

Answer 1

select city,project,rank from table1 order by rank,project,city

Answer 2

尝试这个

 select city, projects, Rank from table order by Rank

Answer 3

在查询中使用ORDER BY子句。

SELECT city, projects, rank FROM table1 
order by rank

Answer 4

这里的很多答案都很好。

然而，在 SQL 中对语言结构使用 UPPERCASE 是常见的做法：

SELECT city,project,rank FROM table1 ORDER BY rank,project;

:-)

Answer 5

我希望这能帮到您：

select city, projects, Rank from table1 
order by Rank, city, projects

您还可以在order by子句中使用位置：

select city, projects, Rank from table1 
order by 3,1,2

0底部的解决方案：

 select city, projects, Rank from table1 
    order by
    case 
     when Rank>0 then 1
     else 2
    end,
    Rank, city, projects

Answer 6

尝试这个...

select city,projects,rank from table1 group by rank order by rank,city,projects;
