Question

我正在努力创建一个动态查询，使用弹簧数据在spel中使用null检查日期。我的疑问是：

 @Query(nativeQuery = true, value = "select a.* from TABLE a where"
        + "(:#{#DateFrom} is null or a.F_DATE >= trunc(:#{#DateFrom}))")
List<Acc> getAccList(@Param("DateFrom") @Temporal(TemporalType.DATE) Date datefrom);

当我使用有效日期运行此查询时，它可以正常工作，但是当我传递null日期时，我会收到以下错误：

org.springframework.dao.InvalidDataAccessResourceUsageException：无法提取ResultSet; SQL [不适用];嵌套异常是org.hibernate.exception.SQLGrammarException：无法提取ResultSet

堆栈追踪：

Answer 1

似乎oracle认为NULL值是二进制值，而不是在尝试对其执行trunc时失败。 Casting it to a Date应该有所帮助。因此，生成的查询应如下所示：

select a.* from TABLE a where (:#{#DateFrom} is null 
or a.F_DATE >= trunc(CAST(:#{#DateFrom} AS DATE))

Answer 2

您需要在'where'关键字后添加一个空格。

import AVKit

使用spring数据在spel中使用日期数据类型进行动态查询
