Question

我刚刚开始使用JackRabbit查询并面临此问题。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

在https://issues.apache.org/jira/browse/JCR-4234

提交的票证

解决方法是使用

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

使用OR和LOWER（）时UnsupportedRepositoryOperationException
