sql - 用于聚合数据的 Oracle sql 查询

Question

我想使用 oracle sql 查询显示如下输出

输入：

name col1 col2      
A     11    12      
B     12    10

输出：

name col1 col2  tot    
A     11    12  23    
B     10    10  20    
tot    21   22  43

Answer 1

尝试：

select coalesce(name, 'Tot') name, 
       sum(col1) col1, 
       sum(col2) col2, 
       sum(col1+col2) tot
from myTable
group by rollup(name)

Answer 2

您要求的内容可以直接使用group by with rollup：

select coalesce(name, 'tot'), sum(col1) as col1, sum(col2) as col2, sum(col1+col2) as total
from t
group by name with rollup
order by (case when name is null then 1 else 0 end), name
