使用 OR 和 LOWER() 时出现 UnsupportedRepositoryOperationException

Question

我刚开始使用 JackRabbit 查询并面临这个问题。此查询在语义上是合理的，但它显示 Unsupportedxxx。删除 LOWER()，它运行没有错误。这是JackRabbit的错误吗？我该如何解决？

查询

SELECT t.*
FROM [nt:base] AS t
WHERE t.[jcr:primaryType] = 'someType'
    OR (LOWER(NAME(t)) = 'a')

例外情况

工单提交于 https://issues.apache.org/jira/browse/JCR-4234

解决方法是使用

... OR LOWER(LOCALNAME(t)) LIKE ...

使用 OR 和 LOWER() 时出现 UnsupportedRepositoryOperationException

UnsupportedRepositoryOperationException when using OR and LOWER()
