使用Query :: executeWithMap（Map parameters）方法时的JDO异常

标签： sql exception jdo

我正在编写一个包含命名参数的动态SQL查询，其中一个是signerName。它在查询中用作以下内容：

"LOWER(`CG_TRANSACTIONSIGNER`.`FIRSTNAME`) LIKE :signerName"

将参数设置为params.put("signerName", signerName);时，Query::executeWithMap(Map parameters)方法将返回错误的[Ljava.lang.Object;集合。它应该返回Transaction的集合。这是完整的堆栈跟踪：

答案 0 :(得分：0)

我弄清楚出了什么问题。实际上，Query::executeWithMap(Map parameters)（[Ljava.lang.Object;的集合返回的结果是正常结果。 [Ljava.lang.Object;类型是java.lang.Object的数组，它是执行SQL查询的结果。此类型不可持久，这就是调用ClassNotPersistenceCapableException方法时抛出PersistenceManager::detachCopy(Transaction pc)异常的原因。
