Oracle sql如果在選擇語句中有條件或分組依據

Question

我有一個表名是ProductDirection。它包括這些列。

1. 操作代碼
2. messagecode
3. productno
4. messages_info
5. 的StatusCode
6. insertdate

我有一個批處理程序，該程序工作最大。一天產品3次。如果某一產品的操作成功批次，當天批次不適用於該產品。所以程序工作的同時它會成功並插入記錄失敗或成功。

我的記錄是：

ProductNo StatusCode MessagesInfo  InsertDate 
--------------------------------------------------------- 
1236895  0   Fail For xxx  01.01.2013 10:00:00 
1236895  0   Fail For yyy  01.01.2013 15:00:00 
1236895  1   Success   01.01.2013 19:00:00 
1236895  0   Fail For xxx  15.01.2013 10:00:00 
1236895  0   Fail For yyy  15.01.2013 15:00:00 
1236895  0   Fail For zzz  15.01.2013 19:00:00 

我想這個條件。如果它有可用的成功記錄，我只想在一天內獲得該記錄，並且如果所有記錄都在一天內失敗。所以我的記錄看起來像這樣。

ProductNo StatusCode MessagesInfo InsertDate 
------------------------------------------------------  
1236895  1   Success   01.01.2013 19:00:00 
1236895  0   Fail For xxx 15.01.2013 10:00:00 
1236895  0   Fail For yyy 15.01.2013 15:00:00 
1236895  0   Fail For zzz 15.01.2013 19:00:00 

我該如何解決？

SELECT * 
    FROM ProductDirection p 
WHERE p.operationcode = 6 
    AND p.messagecode = 2 
    AND trunc(p.insertdate) BETWEEN '01.01.2013' AND '21.06.2013'; 

Answer 1

試試這個。

編輯：

SELECT * 
    FROM productdirection 
WHERE (productno, TRUNC (insertdate)) IN (
             SELECT productno, 
               TRUNC (insertdate) 
              FROM productdirection 
             GROUP BY productno, 
               TRUNC (insertdate) 
              HAVING MAX (statuscode) = 0) 
    OR statuscode = 1;
