如何将多行组合成一行，oracle
How to combine multiple rows in a single row, oracle
我有以下记录：
我想 return 这样的结果：
我加入了很多表后得到了这个结果。所以还是没办法实现这个要求。
注意：我尝试过使用 group by 但没有成功。

有函数名LISTAGG，但在oracle 10g中不起作用。所以我们可以使用 WM_CONCAT Built-in Function 代替，它解决了问题。
If you are not running 11g Release 2 or above, but are running a version of the database where the WM_CONCAT function is present, then it is a zero effort solution as it performs the aggregation for you. It is actually an example of a user defined aggregate function described below, but Oracle have done all the work for you.
但只有 WM_CONCAT 功能的问题是它不会删除重复的单词。所以我们需要将它与 DISTINCT 关键字一起使用，问题就解决了。这是我的最终查询：
