Question

目前我有一个Derby数据库......版本10.11.1.1通过Java应用程序创建，该应用程序仅在运行任意查询的Java应用程序进行通信时才起作用。 Maven依赖如下：

   <dependency>
        <groupId>org.apache.derby</groupId>
        <artifactId>derby</artifactId>
        <version>10.11.1.1</version>
   </dependency>

当我尝试使用ij工具或任何其他第三方应用程序时：

i.e. connect 'jdbc:derby:/home/username/dev/db-agents/TESTDB';

无法这样做，抱怨使用了错误的版本，如下所示：

Caused by: java.sql.SQLException: Database at /home/username/dev/db-agents/TESTDB has an incompatible format with the current version of the software.  The database was created by or upgraded by version 10.11.

我无法理解为什么我可以从Java应用程序连接而不是其他任何东西？有什么特别的我做错了吗？

Answer 1

您的ij会话使用的是旧版本的Derby。

这是由运行ij时设置的CLASSPATH控制的。

仔细查看用于启动ij的脚本或命令，以查看它正在运行的Derby版本。

然后调整run ij时使用的CLASSPATH，以便它使用Derby 10.11，这是Java应用程序使用的版本。

使用工具java代码的ij工具拒绝连接到Derby数据库10.11.1.1
