Question

我的表格包含两列，如下所示。

Object  Value        
------  ------
OBJ1    200   
OBJ2    300  
OBJ2    400  
OBJ1    100

我需要输出如下

OBJ1    OBJ2                     
----    -----
300     700

你能帮我解决这个问题吗？

Answer 1

使用PIVOT：

Oracle安装程序：

CREATE TABLE your_table ( Object, Value ) AS
  SELECT  'OBJ1', 200 FROM DUAL UNION ALL
  SELECT  'OBJ2', 300 FROM DUAL UNION ALL
  SELECT  'OBJ2', 400 FROM DUAL UNION ALL
  SELECT  'OBJ1', 200 FROM DUAL;

<强>查询：

select  *
from    your_table
PIVOT   ( SUM( value ) FOR Object IN ( 'OBJ1', 'OBJ2' ) );

<强>输出：

OBJ1 OBJ2
---- ----
 400  700

Answer 2

只是为了完整性另一种可能性：

select sum(case when object='OBJ1' then value else 0 end) as obj1,
       sum(case when object='OBJ2' then value else 0 end) as obj2
  from yourTable;

Answer 3

试试这个

  select * from
    (select sum(value) Obj1 from yourTable where object= 'OBJ1 ') t1,
    (select sum(value) Obj2 from yourTable where object= 'OBJ2 ') t2

需要帮助以获得pl / sql中的输出
