当我使用存储过程运行以下简单路由时,会导致异常:“java.sql.SQLException: Non supported SQL92 token at position”

具有嵌入式 Derby 数据源的相同路由按预期工作。

问题

有任何想法吗?我的“实现”有问题还是底层 jar 文件有问题?

  • ojdbc7.jar

存储过程: 我知道该过程在 oracle db 中不起作用,但是在所涉及的类/方法识别到该过程不工作/甚至不存在之前“很长时间”抛出异常。

CREATE PROCEDURE INOUTDEMO(IN1 INTEGER, INOUT IN2 INTEGER, OUT OUT1 INTEGER)
 PARAMETER STYLE JAVA
 LANGUAGE JAVA
 EXTERNAL NAME
'org.apache.camel.component.sql.stored.TestStoredProcedure.inoutdemo';

对于 oracle 过程/函数参数,它应该是变量名,后跟输入/输出,然后是数据类型。例如“out1 out integer”

我让它“工作”的唯一方法是这样的:

<to uri="sql-stored: CALL HELLOWORLD(:#testValue,:#result)"/-->

这样 - 没有 IN、INOUT、OUT 或类型参数和“CALL” - 至少可以在 oracle db 中执行存储过程。

不幸的是,我仍在努力将存储过程的返回值映射回驼峰标头或主体变量。
