使用 ij 工具工作的 Java 代码拒绝连接到 Derby 数据库 10.11.1.1

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，该应用程序仅在与运行任意查询的 Java 应用程序通信时才起作用。 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';

不能这样做，抱怨正在使用错误的版本，如下：

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.

我不明白为什么我只能从 Java 应用程序进行连接，而不能通过其他方式进行连接？有什么特别的地方我做错了吗？

Answer 1

您的 ij 会话使用的是旧版本的 Derby。

这由运行 ij 时设置的 CLASSPATH 控制。

仔细查看您用来启动 ij 的脚本或命令，看看它正在运行哪个版本的 Derby。

然后调整您在run ij 时使用的 CLASSPATH，使其使用 Derby 10.11，这是您的 Java 应用程序正在使用的版本。
