如何在sql中对具有相同值的行进行分组并且在应用order by后不打扰？

Question

如何在sql中对具有相同值的行进行分组并且在应用order by后不能打扰。

架构 (PostgreSQL v13)

CREATE TABLE IF NOT EXISTS products (
  id int NOT NULL,
  title varchar(200) NOT NULL,
  description varchar(200) NOT NULL,
  price int NOT NULL,
  PRIMARY KEY (id)
);


INSERT INTO products VALUES
  (1, 'test', 'test',2222),
  (2, 'test', 'test2',1111),
  (3, 'test3', 'test3',1111),
  (4, 'test3.2', 'test3.2',555),
  (5, 'test3.3', 'test3.3',1111),
  (6, 'test4', 'test4 desc',1111);

查询 #1

SELECT DISTINCT
  tempId,pemId, 
  
  title,
  
  description,
  (CASE priceno WHEN 1 THEN price ELSE price END )AS price
  
FROM
(                   
    SELECT 
        
        
        ROW_NUMBER() OVER(PARTITION BY price) AS priceno,
        tempId,pemId,title,description,price
    FROM (
            select id as tempId,id as pemId,title,description,price from products
                group by 
                    
                    grouping sets((tempId,price),(tempId,pemId,title,description))
                
         ) As b
) As s
order by
    
    tempId, price asc;

脾气暴躁	粒	标题	描述	价格
1				2222
1	1	测试	测试
2				1111
2	2	测试	测试2
3				1111
3	3	测试3	测试3
4				555
4	4	测试3.2	测试3.2
5				1111
5	5	测试3.3	测试3.3
6				1111
6	6	测试4	测试4描述

查询 #1

select id, 
title, 
description,
(CASE WHEN prno=1 THEN price::varchar ELSE '' END )AS price
from(
  select DISTINCT id, title, description, price, prno
from (
  select id, 1, null, null, null, price::varchar, 1 as prno from products
  union all
  select id, 2, id::varchar, title, description, price::varchar, 2 as prno from products
) temp1 (xid, xord, id, title, description,price,prno)
 order by price, prno
) as temp2;

ID	标题	描述	价格
			1111
2	测试	测试2
6	测试4	测试4描述
3	测试3	测试3
5	测试3.3	测试3.3
			2222
1	测试	测试
			555
4	测试3.2	测试3.2
