生成列導致

Question

我有四個支點，我從這個樣子拉着數據：

tracked_work_by_users_by_operation_pivot: 
+-------------------+---------------+---------------+-----------------------+---------------+ 
| DATE(start_time) | userid  | operation_id | Time estimated  | Time Elapsed | 
+-------------------+---------------+---------------+-----------------------+---------------+ 
| 1/2/2011-1/8/2011 | jsmith  |    11|      40|    40| 
| 1/2/2011-1/8/2011 | jsmith  |    10|      20|    24| 
+-------------------+---------------+---------------+-----------------------+---------------+ 

faults_by_user_pivot: 
+-------------------+---------------+---------------+-----------------------+----------+ 
| date(date_entered)| userid  | operation_id | Major     | Minor | 
+-------------------+---------------+---------------+-----------------------+----------+ 
| 1/2/2011-1/8/2011 | jsmith  |    11|      2 |   1| 
+-------------------+---------------+---------------+-----------------------+----------+ 

paid_hours_by_user_pivot: 
+-------------------+---------------+---------+ 
|date_range   | userid  | Total | 
+-------------------+---------------+---------+ 
| 1/2/2011-1/8/2011 | jsmith  | 40  | 
+-------------------+---------------+---------+ 


tracked_work_by_users_pivot: 
+-------------------+---------------+---------+ 
|DATE(start_time) | userid  | Total | 
+-------------------+---------------+---------+ 
| 1/2/2011-1/8/2011 | jsmith  | 24  | 
|     |    |   | 
+-------------------+---------------+---------+ 

我需要做的是編譯爲每個用戶每次操作的報告。從我看到這樣做的最好辦法是有類似的格式：

     +--------------+--------------+            +--------------+--------------+ 
        | jsmith | packaging |            | jsmith  | machining | 
+--------------------+--------------+--------------+----------------+--------------+--------------+--------------+--------------+----------------+--------------+--------------+ 
| DATE   | time_elapsed | hours_worked | estimated_work | minor_faults | major_faults | time_elapsed | hours_worked | estimated_work | minor_faults | major_faults | 
+--------------------+--------------+--------------+----------------+--------------+--------------+--------------+--------------+----------------+--------------+--------------+ 
| 1/2/2011-1/8/2011 |   24 |   40 |    36 |   1 |   2 |   24 |   40 |    36 |   1 |   2 |    
+--------------------+--------------+--------------+----------------+--------------+--------------+--------------+--------------+----------------+--------------+--------------+ 

這樣JSMITH將加工和包裝單獨的條目，因爲我們希望能夠排名使他對所有加工經營和所有包裝經營者。我怎樣才能最好地做到這一點，以便我每次添加新用戶時都不必再添加12個條目（因爲有12個操作）？

做到這一點的最好方法似乎是簡單地寫一個應用程序，而不是強大的武裝Excel。
