我如何简化这些行。我有数百行设置每个表格单元格中的值。

         dailyResult("SELECT COUNT(*) FROM fault WHERE Type = 'E-MAIL FAULT' AND No_Fault_Number <> 'No Fault Number' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 77, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE Type = 'E-MAIL FAULT' AND No_Fault_Number = 'No Fault Number' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 78, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE CMTS = 'SJ1' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 80, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE CMTS = 'SJ2' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 81, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE CMTS = 'SJ3' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 82, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE CMTS = 'ALA1' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 83, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE CMTS = 'ALA2' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 84, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE CMTS = 'FVW' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 85, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE CMTS = 'MND1' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 86, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE Call_Concern = 'Slow Connection' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 88, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE Call_Concern = 'No Connection' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 89, 1); 
         dailyResult("SELECT COUNT(*) FROM fault WHERE Call_Concern = 'Intermittent Connection' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 90, 1);

只是看着它让我感觉很糟糕，我需要找出是否有一个循环来简化它？任何类型的帮助都会很棒。

这是顺便说一句的方法代码。

  public void dailyResult(String q, int x, int y){

    try{
        Statement stmtDr = (Statement)daily.createStatement();
        ResultSet rs = stmtDr.executeQuery(q);
    if(rs.next()){
        reportTable1.setValueAt(rs.getInt(1), x, y);
    }
    }catch(Exception e){
                   JOptionPane.showMessageDialog(rootPane, "Error 106\n\nAn error has occured with the resultset procedure method. Please try again later.", "Error!", JOptionPane.ERROR_MESSAGE);

您可以在查询中使用 group by，替换它

dailyResult("SELECT COUNT(*) FROM fault WHERE CMTS = 'MND1' AND CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year , 86, 1);

和

dailyResult("SELECT CMTS,COUNT(*) FROM fault WHERE CallTypeInt = 'TRI' AND DC_Month = " + month + " AND DC_Day = " + day + " AND DC_Year = " + year +" GROUP BY CMTS", 86, 1);

然后在 dailyResult

ResultSet rs = stmtDr.executeQuery(q);
while(rs.next()){  // we are expecting multiple rows now
    String faultType = rs.getString(1);//what fault is this?
    reportTable1.setValueAt(rs.getInt(2), getXOffset(faultType), y);
}

需要注意的是，如果没有发现错误，则不会返回任何行，但这与您现在的行为相同，所以我假设您正在满足这一点。

对这些查询使用存储过程，并使用group by命令来减少查询的长度。

实际上，我注意到 CMTS、Call_Concern 等在每个查询中的用途不同。也许您可以将一些查询合并为一个，但我不认为所有这些都可以以目前的格式组合在一起。参数化这些列。他们全部。也许您需要研究业务逻辑才能做到这一点。完成后，您可以对整个内容进行一次查询。
