我有一个使用Advantage DB的客户机,我正在尝试使用JDBC进行连接。
我的网址如下
jdbc:extendedsystems:advantage://localhost:6262;catalog=C:\Program Files (x86)\company\CMWin\Data\cmwin.add
当我连接(当前使用数据报,但其他所有内容都是相同的错误)时,我得到一个
java.lang.AbstractMethodError: Method com/extendedsystems/jdbc/advantage/ADSDatabaseMetaData.supportsSavepoints()Z is abstract
我知道JDBC驱动程序工作正常,但我不完全确定出了什么问题。
现在我看到了这些表,但是当我试图访问它们时,我遇到了上面的错误,而且
