java - Camunda 在启动期间在本地 oracle 数据库上引发错误

Question

更新，我发现问题，我在类路径中有 h2，而 camunda 在 h2 上运行它

Camunda 在本地 Oracle 数据库上引发错误，数据库为空。 Flyway 脚本工作正常，但之后我可以在日志上看到此错误。 。当我尝试在非本地的 oracle 上启动应用程序(相同的版本)(再次使用干净的 oracle db)时，我没有收到任何错误。

查询数据库时出错。原因:java.sql.SQLSyntaxErrorException:ORA-00933:SQL命令未正确结束

Answer 1

我不认识Camunda，但日志中显示的查询确实没有正确结束。

LIMIT ? OFFSET ?

这看起来像 Postgres 。 Oracle top-n syntax将是:

offset ? rows fetch next ? rows only
