假设有个表TBLA,
表里字段为 AA，BB，CC
我想取得的数据Result是这样的，AA,BB,CC,AA1,BB1,CC1,AA2,BB2,CC2
意思就是想要一次性取得三条数据，然后把后面2条数据的字段重命名一下，比如AA->AA1
------解决方案--------------------
写的有点麻烦..
- SQL code
create table t1 (AA varchar2(20), BB varchar2(10), CC number(3));insert into t1 values ('jack','A',80);insert into t1 values ('rose','B',60);insert into t1 values ('lucy','C',70);insert into t1 values ('lili','A',95);insert into t1 values ('lei','B',85);insert into t1 values ('doufu','C',75);commit;select wm_concat(decode(rn,1,aa,null)) AA,wm_concat(decode(rn,1,bb,null)) bb,wm_concat(decode(rn,1,cc,null)) cc, wm_concat(decode(rn,2,aa,null)) AA1,wm_concat(decode(rn,2,bb,null)) bb1,wm_concat(decode(rn,2,cc,null)) cc1, wm_concat(decode(rn,3,aa,null)) AA2,wm_concat(decode(rn,3,bb,null)) bb2,wm_concat(decode(rn,3,cc,null)) cc2from(select AA,BB,CC,rownum rn from t1 where rownum<=3) AA BB CC AA1 BB1 CC1 AA2 BB2 CC2-----------------------------1 jack A 80 rose B 60 lucy C 70
