查询以从表中获取数据作为另一个表中的列名

Question

我创建了一些示例表和数据来尝试LISTAGG

SELECT SALE_TITLE, addr_id, addr_name, addr_desc
         , LISTAGG(SALES_ID, ',')
             WITHIN GROUP (ORDER BY SALES_ID)
             AS SALES_ID
    FROM   (select a.addr_id, a.addr_name, a.addr_desc, 
                   b.SALES_ID, b.SALE_TITLE, 
                   ROW_NUMBER () OVER (ORDER BY b.SALES_ID ) rn,
                   COUNT (*) OVER () cnt
            from palm.adrss a, palm.sales b 
            where a.addr_id = b.addr_id) 
   GROUP BY SALE_TITLE, addr_id, addr_name, addr_desc;

当我运行上面的查询时，我的结果集如下

+-----------------+----------+-----------+--------------+-------------+
|     SALE_TITLE  |  ADDR_ID | ADDR_NAME |  ADDR_DESC   |  SALES_ID   |
+-----------------+----------+-----------+--------------+-------------+
|     Role        |        2 | saty      | local test   | 14,34       |
|     Entitlement |        2 | saty      | local test   | 22,42       |
|     Role        |        3 | vasu      | portal       | 14,34       |
|     Entitlement |        3 | vasu      | portal       | 22,42       |
|     Role        |        4 | sand      | Golden gate  | 144,344     |
|     Entitlement |        4 | sand      | Golden gate  | 224,424     |
|     Role        |        5 | Gou       | Data Modeler | 144         |
|     Suffix      |        5 | Gouri     | Data Modeler | 224,424     |
|     Entitlement |        5 | Gou       | Data Modeler | 344         |
|     Role        |        6 | Mad       | Data Analyst | 144         |
|     Entitlement |        6 | Mad       | Data Analyst | 224,344,424 |
+-----------------+----------+-----------+--------------+-------------+

现在使用此结果集，我想编写另一个查询以获取如下所示的结果集。 在此角色中，权利，后缀将是列名，并且在其下具有sale_id

+---------------+--------------+---------+----------------------+---------+
|     ADDR_NAME |  ADDR_DESC   |  Role   | Entitlement          | Suffix  |
+---------------+--------------+---------+----------------------+---------+
|        saty   | local test   | 14,34   | 22,42                |         |
|        vasu   | portal       | 14,34   | 22,42                |         |
|        sand   | Golden gate  | 144,344 | 224,424              |         |
|        Gou    | Data Modeler | 144     | 344                  | 224,424 |
|        Mad    | Data Analyst | 144     | 224,344,424          |         |
+---------------+--------------+---------+----------------------+---------+

请让我知道是否可行，并提供一些意见

提前致谢

我看到您在示例数据上有错字，如果修复它，您将得到所需的输出。

update Your_Table
set ADDR_NAME='Gou'
where ADDR_NAME='Gouri'

您的查询应为：

    select t1.ADDR_NAME,t1.ADDR_DESC,
    max(case when t1.SALE_TITLE='Role'  then t2.SALES_ID end) 'Role',
    max(case when t1.SALE_TITLE='Entitlement'  then t2.SALES_ID end) 'Entitlement',
    max(case when t1.SALE_TITLE='Suffix'  then t2.SALES_ID end) 'Suffix'
    from  Your_Table t1
    join  Your_Table t2
    on t1.ADDR_ID=t2.ADDR_ID and t1.SALE_TITLE=t2.SALE_TITLE
    group by  t1.ADDR_NAME,t1.ADDR_DESC
    order by Role
