oracle 11g行转列列转行

行转列：

SELECT *
FROM src_table
UNPIVOT (param_value FOR param_name IN (product_color AS 'product_color', product_type AS 'product_type', is_intelligent AS 'is_intelligent'));

列转换：

select * from (

select flow,xx from tab

) a pivot (max(value) for enname in ( 'flow' flow ,'xx')) b order by id ";

我自己的测试

注意：建表插入的时候varchar字符型必须要加上'',

 insert into s1 values('yuan','english',80);

SELECT * FROM s1

PIVOT ( MAX(score) for subject IN( 'chinese' chinese , 'math' math , 'english' english ) )

注意这里max的是分数，in的是subject

返回来

  SELECT * FROM 
   ( SELECT * FROM s1
    PIVOT ( MAX(score) for subject IN( 'chinese'  chinese , 'math'  math  , 'english'  english ) ) )
 UNPIVOT ( score FOR subject IN (   chinese ,   math  ,   english ) )

注意这里最后一句的in chinese 之类，chinese不需要加''
