pivot的格式 select * from ( inner_query) pivot(aggreate_function for pivot_column in ( list of values)) order by ...; 用法举例: select * from ( select month,prd_type_id,amount from all_sales ) pivot (sum(amount) for month in (1 as JAN,2 as FEB,3 as MAR,4 as APR) ) order by prd_type_id
转换多个列 select * from (select month,prd_type_id,amount from all_sales ) pivot(sum(amount) for (month,prd_type_id) in ( (1,2) as JAN_P2,(2,3) as FEB_P3) );
在转换中使用多个聚合函数 select * from (select cust_no,mag_man_cert_type,t.mag_man_cert_no,mag_man_type from L_CIF_ENT_CUST_MAG_MAN_INFO t pivot (max(mag_man_cert_NO) as no ,max(mag_man_cert_type) as type for mag_man_type In ('01' as GLR01,'02' as GLR02,'03' as GLR03));
unpivot可以实现列转行,所转的列的字段类型必须一致 unpivot 的用法举例： select * from PIVOT_SALES_DATE unpivot (amount for month in (JAN,FEB,MAR,APR));
