我有一個應用程序，它以xml格式從YQL表yahoo.finance.quotes下載財務數據，然後將此數據寫入MS Access數據庫。我正在使用Jackcess與數據庫進行交互，但我在添加行時遇到了一個奇怪的問題。Jackcess列不按順序？
當我打電話給.addRow（）所有的字段都被正確地寫入文件，除了少數被切換。這是我會下載和使用（與JAXB）的XML文件的例子...

而這裏的結果訪問數據庫的XML導出...

這裏是我的代碼從XML值添加到數據庫中，如果有幫助...

dBTable.addRow(id, bookValue, earningsShare, epsEstimateCurrentYear, epsEstimateNextYear, epsEstimateNextQuarter, daysLow, daysHigh,

peRatio, pegRatio, priceEPSEstimateCurrentYear, priceEPSEstimateNextYear, shortRatio, oneyrTargetPrice, volume, ask, averageDailyVolume, bid);
}
正如你所看到的只限於上次交易價格，短線比例，交易量爲和平均日交易量爲左右。
有人能告訴我爲什麼這是，以及如何糾正它？謝謝。
