Question

UPSERT_DELETE_JOB_COUNTERS가 업데이트되었습니다. 이제 "업서 트"가 새로운 쿼리 =와 함께 작동한다고 생각하십니까? 아니면 어떻게 생각하십니까?

관련, 피터

`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(); 
     }...

당신은 DO 문을 매개 변수화 java.sql.PreparedStatement을 사용할 수 없습니다.

INSERT ... ON CONFLICT DO UPDATE (PostgreSQL 9.5부터 사용 가능)을 사용하지 않는 이유는 무엇입니까?

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