最近在维护一个项目，出现了一下bug需要进行调试，于是把正式库上面的代码搬到本地库上面，数据库是本地的，跑项目的时候调试发现代码里面带有wmsys.wm_concat函数的SQL语句出现错误，经排查发现本地测试库用的是oracle 11g版本，比正式库上的版本高，解决方式这分享给大家：

wmsys.wm_concat是oracle 10g推出的，用来连接字符串，LISTAGG是oracle 11g推出的，它的作用和wmsys.wm_concat是一样的。

select listagg(p.id_card,‘,‘) within group(order by p.PERSON_ID) PERSON_IDCARDS from cbms_lib_person p where p.person_id in (136565,158756,158762,158761,149569,153512,89376,70196)
