这三个文件在哪里下载,"owmctab.plb","owmaggrs.plb","owmaggrb.plb"

Where to download these three files, "owmctab.plb","owmaggrs.plb","owmaggrb.plb"

我需要使用 WM_CONCAT() 函数,但是 oracle 11g 没有。

Some articles say the problem can be fixed through these three files "owmctab.plb,owmaggrs.plb,owmaggrb.plb".

所以我想下载那个文件,在哪里可以下载?

请给我一些线索!谢谢!

WM_CONCAT 是一个 未记录的 函数,因此 Oracle 不支持 用户应用程序,甚至 DB version 11 Release 2+ 中不存在

您可以使用 listagg() 函数替代

select deptno, listagg(ename, ',') within group (order by ename) as employees
  from emp
 group by deptno;

而不是

select deptno, wm_concat(ename, ',') as employees
  from emp
 group by deptno;
