Oracle如何設置數據透視表SQL

我有一個表列，如Question_Id，Department_Id，Value。Oracle如何設置數據透視表SQL

這裏是我的數據：

enter image description here

我希望得到像這樣的表：

這裏是我的代碼：

SELECT * 
FROM (SELECT question_id, department_id, TO_NUMBER(value) 
     FROM my_pivot_table) 
     PIVOT (SUM(TO_NUMBER(value)) AS sum_quantity FOR (department_id) IN (11 AS a, 12 AS b, 13 AS c, 14 AS d, 5 as e)) 

ORDER BY question_id;

我得到這個錯誤[R，但我不什麼是錯

ORA-01722: invalid number 
01722. 00000 - "invalid number" 
*Cause:  
*Action:

編輯：

我發佈，我的值列是VARCHAR。所以我改變了我的代碼，但仍然沒有得到我的數據透視表。

確保'value'的數據類型是數字，沒有必要寫在清單報價'（11 A，12 B，13 c，14 as d，5 as e）'應該有效。 – San 2015-04-03 07:21:16

和一些示例數據？ – 2015-04-03 07:22:27

我改變了我的代碼。謝謝 – ispanak 2015-04-03 07:26:49

看起來你需要移動括號：

SELECT * 
FROM (SELECT question_id, department_id, TO_NUMBER(value) 
     FROM my_pivot_table -- right parenthesis was here 
     PIVOT (SUM(TO_NUMBER(value)) AS sum_quantity 
       FOR (department_id) IN (11 AS a, 12 AS b, 13 AS c, 
        14 AS d, 5 as e))) -- and moved here 
ORDER BY question_id;
