oracle列转行 WM_CONCAT LISTAGG

开发给个SQL说给某个条件时报ORA-22922

代码段：

 SELECT 袋号,
                     SUM(实际重量) AS 实际重量,
                     SUM(材积重量) AS 材积重量,
                     COUNT(运单号) AS 件数,
                     TO_CHAR(WMSYS.WM_CONCAT(运单号)) AS 运单编号
                FROM TBL
               GROUP BY 袋号

修改成如下后解决：

 SELECT 袋号,
        SUM(实际重量) AS 实际重量,
        SUM(材积重量) AS 材积重量,
        COUNT(运单号) AS 件数,
        LISTAGG(运单号, ',') WITHIN GROUP(ORDER BY 运单号) AS 运单编号
   FROM TBL
  GROUP BY 袋号

注：

LISTAGG为11G2才提供的函数
