我有一個Stored procedure在PLSQL其中根據某些條件插入和更新記錄。更新列在Oracle PLSQL中不起作用
現在這裏的問題是。在第一次插入記錄時，它根據需要正確插入記錄，但是
在更新它時不更新表的記錄。
下面是SP

注意
雖然更新記錄我的TBL_INSERT收益爲NULL
'tbl_insert'似乎沒有被定義，並且在第54行之前缺少右括號，但那些將是編譯錯誤。你能否確認'vsat_detail_id'是通過觸發器設置的？你可能會得到一個例外，但是因爲你在別人的時候被你壓制/隱藏它。通常在程序中提交/回滾通常不是一個好主意，但是如果你必須捕捉異常，你應該重新提高它。 （在'rollback'之後加'raise;'）。也看看保存點.... –
@AlexPoole：真的非常感謝您的評論，是'vsat_detail_id'通過觸發器設置。另外我怎麼能知道它給我一個'例外'，因爲我無法找到它。如果你讓我知道處理這件事，IT會很棒。 – BNN
我已經說過了，在用'when others'緩存後重新拋出異常。但是，正如user7294900指出的那樣，您用於更新的值設置爲零，而不是您期望的值 - 來自之前的「select」....但您仍然可能會遇到異常，例如如果'v_count'大於1，而不是完全爲1. –
