以表格格式输出

Question

我在oracle中有一个sql表，如下所示，它的名字就是范围。

SPECIALIST   CONTENTS UPDATE_COUNT 
Ram     Updates   23 
Har     Legis    6 
Ram     Updates   65 

我想输出格式在下面的格式请帮助我。

  Har Ram Total 
Updates 0 88 88 
Legis 6 - 6 
Total 6 88 94

您没有指定要使用甲骨文的版本。如果你在Oracle 11g中，那么你可以使用PIVOT函数。如果不是，那么您可以使用CASE语句的聚合函数。下面是如何产生的结果severl版本：

select contents, 
    sum(case when specialist = 'Har' then update_count else 0 end) Har, 
    sum(case when specialist = 'Ram' then update_count else 0 end) Ram, 
    sum(case when specialist in('Har', 'Ram') then update_count else 0 end) Total 
from yourtable 
group by contents 
union all 
select 'total', 
    sum(case when specialist = 'Har' then update_count else 0 end) Har, 
    sum(case when specialist = 'Ram' then update_count else 0 end) Ram, 
    sum(case when specialist in('Har', 'Ram') then update_count else 0 end) Total 
from yourtable

或者你可以使用GROUP BY ROLLUP：

select 
    case when contents is null then 'Total' else contents end contents, 
    sum(case when specialist = 'Har' then update_count else 0 end) Har, 
    sum(case when specialist = 'Ram' then update_count else 0 end) Ram, 
    sum(case when specialist in('Har', 'Ram') then update_count else 0 end) Total 
from yourtable 
GROUP BY rollup(contents);

或者你可以使用PIVOT用ROLLUP：

select 
    case when contents is null then 'Total' else contents end contents, 
    sum(coalesce(Har, 0)) Har, 
    sum(coalesce(Ram, 0)) Ram, 
    sum(coalesce(Har, 0) + coalesce(Ram, 0)) Total 
from 
(
    select specialist, contents, update_count 
    from yourtable 
) src 
pivot 
(
    sum(update_count) 
    for specialist in ('Har' as Har, 'Ram' as Ram) 
) piv 
group by rollup(contents)
