Question

UPDATE ，我发现问题，我在课程路径中有h2，而且camunda在h2上运行了

Camunda在本地oracle db上抛出错误，db为空。 Flyway脚本工作正常，但之后我可以在日志中看到此错误。。当我尝试在非本地的oracle上启动app（相同版本）时（再次使用干净的oracle db）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

我不了解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

Camunda在启动期间在本地oracle db上抛出错误
