Question

我试图使用NetBeans＆＃39;内置数据库服务系统和UCanAccess JDBC驱动程序，以连接到MS Access数据库。从服务面板拖放表以将它们连接到我的Swing GUI中的JTable后，一切似乎都在工作，但是一旦我尝试运行程序，我就会收到以下错误：

在查看错误之后，我认为它很可能是连接错误，但是在创建连接时没有显示错误，并且在服务选项卡中所有表都显示正确：

Services Tab

有谁知道我的问题可能是什么？

编辑：将UCanAccess从2.0.9.5更新到3.0.0后，我仍然收到错误但是有点不同

再次感谢您提供的任何帮助。

Answer 1

要从公共架构拖放，而不是从INFORMATION_SCHEMA拖放，解决了这个问题。这是由于3.0.0中已经解决的数据库元数据错误。

使用NetBeans IDE的数据库管理器和UCanAccess JDBC驱动程序
