列索引超出範圍：1，列數：0

-1

我更新了UPSERT_DELETE_JOB_COUNTERS。現在我認爲「upsert」與新的Query =一起工作）或者你認爲如何？列索引超出範圍：1，列數：0

問候，彼得

`private static final String UPSERT_DELETE_JOB_COUNTERS = 
     "UPDATE rating.delete_job_counters SET delete_count = delete_count + ? WHERE fee_group_id = ? AND delete_job_id = ?; "+ 
     "INSERT INTO rating.delete_job_counters(delete_job_id, fee_group_id, delete_count) "+ 
     "SELECT ?, ? , ? " + 
     "WHERE NOT EXISTS (SELECT 1 FROM rating.delete_job_counters WHERE fee_group_id = ? AND delete_job_id = ?); "; 

@Override 
public Boolean insertIntoDeleteStatistic(final CachedRowSet deletedEntries, 
             Long deleteJobId, 
             Transaction transaction) throws SQLException { 
    boolean finish = true; 
    if (deletedEntries.size() == 0) { 
     return finish; 
    } 
    final Connection connection = transaction.getConnection(); 
    final Timer executeTimer = Timer.start("Insert took "); 
    try { 
     PreparedStatement pstmt = connection.prepareStatement(UPSERT_DELETE_JOB_COUNTERS); 
     while (deletedEntries.next()) { 
      pstmt.setInt(1, deletedEntries.getInt(2)); 
      pstmt.setInt(2, deletedEntries.getInt(1)); 
      pstmt.setLong(3, deleteJobId); 
      pstmt.setLong(4, deleteJobId); 
      pstmt.setInt(5, deletedEntries.getInt(1)); 
      pstmt.setInt(6, deletedEntries.getInt(2)); 
      pstmt.setInt(7, deletedEntries.getInt(1)); 
      pstmt.setInt(8, deletedEntries.getInt(2)); 
      pstmt.execute(); 
     }...

我相信'deleteCdr.getInt（2）'是問題的原因。你確定這個緩存結果集實際上有兩列嗎？ –

與您的問題沒有直接關係，但需要關閉「Statement」和「Connection」。考慮[try-with-resources]（https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html）。 – bradimus

'UPDATE rating.delete_job_counters SET delete_count = delete_count +？在哪裏fee_group_id =？ AND delete_job_id =？; INSERT INTO rating.delete_job_counters（delete_job_id，fee_group_id，delete_count） SELECT？，？，？ WHERE NOT EXISTS（SELECT 1 FROM rating.delete_job_counters where fee_group_id =？AND delete_job_id =？）; '這個查詢好嗎？我的第一個測試是積極的。 – user3181885

不能使用參數化java.sql.PreparedStatement與DO聲明。

爲什麼不使用INSERT ... ON CONFLICT DO UPDATE（自PostgreSQL 9.5以後可用）？

對於舊版本的PostgreSQL，你可能有這樣的僞代碼樣本代碼的「無限循環」：

while (1) { 
    INSERT ... 
    if (insert went ok) break; 
    UPDATE ... 
    if (update changed one row) break; 
}

我們有PostgresSql 9.4 =（你有另一個想法嗎？ – user3181885

我已經編輯了答案;我想這是你唯一的選擇。 –
