如何在postgresql中垂直显示我的查询结果？

这是我的SQL查询，我想要这些结果垂直显示。我也搜索谷歌这一点，我发现通过使用\x\g\x打开切换模式，但我不知道该把语法放在哪里。请帮助得到的输出是这样的：如何在postgresql中垂直显示我的查询结果？

但是，我的这个查询给出输出是这样的：

   select 
      round(
      100.00 * 
      (sum(case when "WELL_AGE" <= '5' AND "CONC_ARSC" <= '10' then 1 else 0 end))/(sum(case when "WELL_AGE" <= '5' then 1 else 0 end)),1) conc_arscbelow5_wellageGrp, 

      round(
      100.00 * 
      (sum(case when "WELL_AGE" >= '6' AND "WELL_AGE" <= '10' AND "CONC_ARSC" <= '10' then 1 else 0 end))/(sum(case when "WELL_AGE" >= '6' AND "WELL_AGE" <= '10' then 1 else 0 end)),1) conc_arscbet6_10wellageGrp, 

      round(

看到这个http://stackoverflow.com/questions/23060256/postgres-transpose-rows-to-columns –

'\ x'命令只对命令行客户端'psql'有效，它将简单地“旋转”任何SQL查询的输出。没有'psql' metacommand'\ x \ g \ x'。 '\ g'将从编辑缓冲区运行语句。 –

那么，我需要做些什么来实现我的需求呢？ –

我希望这将匹配您的要求。

使用hstore：

with t as (SELECT '80.13' aS "0-5", '80.7' AS "6-10", '81.6' AS "11-15", '84.27' AS "16-30", '84.04' AS "31-50", '85.33' AS ">50") 
SELECT * 
FROM (SELECT (each(hstore(t))).* FROM t) AS tmp (well_age, below10_conc_arsc_wells)

与表替换吨。使用JSON：

with t as (SELECT '80.13' aS "0-5", '80.7' AS "6-10", '81.6' AS "11-15", '84.27' AS "16-30", '84.04' AS "31-50", '85.33' AS ">50") 
SELECT * 
FROM (SELECT (json_each_text(row_to_json(t))).* FROM t) AS tmp (well_age, below10_conc_arsc_wells)

使用range type到组：

with r (r,s) as (values 
    (int4range(null,5,'[]'), '0 - 5'), 
    (int4range(6,10,'[]'), '6 - 10'), 
    (int4range(11,15,'[]'), '11 - 15'), 
    (int4range(16,30,'[]'), '16 - 30'), 
    (int4range(31,50,'[]'), '31 - 50'), 
    (int4range(50,null,'(]'), '>50') 
) 
select s, 100* count("CONC_ARSC" <= '10' or null)/count(*) 
from 
    public."Arsenic_Test" 
    inner join 
    r on "WELL_AGE" <@ r 
group by s;
