Informix - 基于id连接同一列中包含的数据

Question

我需要在Informix中基于id连接相同字段中的字符串。我意识到这可以在MSSQL中轻松完成。

以下是我当前表格的一个示例：

id | doc_num | page_num | description
-------------------------------------------------
1  |  1      |    1     | This is the story about
1  |  1      |    2     | a girl named Daisy.    
1  |  2      |    1     | Daisy had a dog named
1  |  2      |    2     | Rover.
2  |  1      |    1     | This story is about Bob.
2  |  2      |    1     | Bob is a DBA who works
2  |  2      |    2     | at an important company
2  |  2      |    3     | that develops important
2  |  2      |    4     | software.

期望的输出：

id |  description
------------------------------------------------------------
1  |  This is a story about a girl named Daisy.
   |  Daisy has a dog named Rover.
------------------------------------------------------------   
2  |  This story is about Bob.  Bob is a DB who works at an
   |  important company that develops important software.
------------------------------------------------------------

我在这里找到了答案： https://dba.stackexchange.com/questions/65101/multiple-table-rows-in-one-row-informix

由于我正在运行Informix 12，它使用rank（）over（）sys_connect_by_path（）。
