Question

SQL Delete查询无法在骆驼中工作，因为它卡在SQL查询中，没有任何反应。试图直接在DB中执行相同的查询，它按预期工作正常。下面是代码的简要介绍。

            </onException>
        </route>
    </camelContext>
</beans>

我正在使用dbcp2，pool2和camel-sql组件连接到数据库。

有什么建议吗？

已经发现了问题，我已经创建了自己的表，但是错过了删除权限的授予，因此它没有从骆驼组件中删除数据库中的数据，所以我授予了表的权限，并且可以正常工作。

SQL删除查询不适用于Apache骆驼
