oracle中行转列语句参考

建表语句：

drop table test purge;create table test(id number,name varchar2(20),score number);insert into test values(1,'a',95);insert into test values(1,'b',82);insert into test values(1,'c',73);insert into test values(2,'d',56);insert into test values(2,'e',74);commit;

字符类型列合并：

select id 代号,wm_concat(name) 合并结果 from test group by id;

非字符类型列合并：

select id 代号,wm_concat(to_char(score)) 合并结果 from test group by id;
