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
### The error may exist in org/camunda/bpm/engine/impl/mapping/entity/Job.xml
### The error may involve org.camunda.bpm.engine.impl.persistence.entity.JobEntity.selectNextJobsToExecute-Inline
### The error occurred while setting parameters
### SQL: select RES.* from ACT_RU_JOB RES where (RES.RETRIES_ > 0) and (RES.DUEDATE_ is null or RES.DUEDATE_ <= ?) and (RES.LOCK_OWNER_ is nu

from ACT_RU_JOB J2 where J2.PROCESS_INSTANCE_ID_ = RES.PROCESS_INSTANCE_ID_ -- from the same proc. inst.

最佳答案
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
关于java - Camunda 在启动期间在本地 oracle 数据库上引发错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50641551/
