我在我的web應用程序中使用了Quartz作業。當我使用Quartz 1.6.5和Teradata數據庫版本13.10時，一切正常。石英錯誤：沒有合適的驅動程序
我在石英老版本中遇到了頻繁的死鎖問題。所以，我將我的版本升級到Quartz2.2.1。當我在Teradata數據庫版本13.10中使用Quartz 2.2.1時，一切正常。
後來我們在Teradata 13.10中遇到了一個奇怪的charset問題，所以我們升級到了Teradata 14.0。現在
，我們面臨着一個奇怪的問題，當我們用石英2.2.1和Teradata數據庫版本14.0
我們得到了以下異常，

我們正面臨着只有上面說的，當石英數據庫表是空的。如果石英錶包含作業細節，作業運行良好。
任何一個建議可以引起什麼問題？我在這裏做錯了什麼？
