oracle多列转一行

贺挺 — Wed, 03 Mar 2010 09:49:00 GMT

create table m_researcher_stock_rel(N_SEC_CODE  CHAR(6)
, C_RESEARCHER_CODE varchar(20))
drop table m_researcher_stock_rel

select * from m_researcher_stock_rel
insert into m_researcher_stock_rel values('000297', 'chenpeng');
insert into m_researcher_stock_rel values('000297', 'peopeo');
insert into m_researcher_stock_rel values('000297', 'aaa');
insert into m_researcher_stock_rel values('000297', 'bbb');
insert into m_researcher_stock_rel values('000297', 'ccc');
SELECT    n_sec_code, TRANSLATE (LTRIM (text, '/'), '*/', '*,') researcherList
    FROM (SELECT ROW_NUMBER () OVER (PARTITION BY n_sec_code ORDER BY n_sec_code,
                   lvl DESC) rn,
                  n_sec_code, text
            FROM (SELECT      n_sec_code, LEVEL lvl,
                              SYS_CONNECT_BY_PATH (c_researcher_code,'/') text
                        FROM (SELECT    n_sec_code, c_researcher_code as c_researcher_code,
                                        ROW_NUMBER () OVER (PARTITION BY n_sec_code ORDER BY n_sec_code,c_researcher_code) x
                                  FROM m_researcher_stock_rel
                              ORDER BY n_sec_code, c_researcher_code) a
                   CONNECT BY n_sec_code = PRIOR n_sec_code AND x - 1 = PRIOR x))
   WHERE rn = 1
ORDER BY n_sec_code;

预想的结果成功出现，多行数据成功汇总到一行，特此分享与大家。对于你自己的应用中，只需要把SQL中“n_sec_code”
换为你的用来汇总的列，“c_researcher_code”替换为需合并文本的列，“m_researcher_stock_rel”替换为你的表名，就是这么简单。
