将 NetBeans IDE 的数据库管理器与 UCanAccess JDBC 驱动程序一起使用
Using NetBeans IDE's database manager with UCanAccess JDBC driver
我正在尝试使用 NetBeans 的内置数据库服务系统和 UCanAccess JDBC 驱动程序连接到 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 该程序，我就会收到以下错误：

查看错误后，我认为这很可能是连接错误，但是在创建连接时没有显示任何错误，并且在服务选项卡中所有表都正确显示：

编辑：将 UCanAccess 从 2.0.9.5 更新到 3.0.0 后，我仍然收到错误，但略有不同

再次感谢您提供的任何帮助。
从 public 架构而不是 INFORMATION_SCHEMA 拖放可以解决问题。这是由于数据库元数据错误已在 3.0.0 中解决。
