字符串是可能含有大小写的, 在String::compareTo中认为A和a是不同的, 那么在忽略大小写的场景中就不适用了;既然String提供了基于Comparator的内部类, 是不是对这种场景做了特殊处理呢?我们接下来看CaseInsensitiveComparator的核心实现: 可以看到compare的逻辑和String:compareTo大同小异, 只是在第二步的时候做了特殊...
CASE_INSENSITIVE_ORDER是CaseInsensitiveComparator类的对象，这个类是String类的内部类，并且实现了Comparator接口。那再看看这个CaseInsensitiveComparator是怎么实现Comparator接口的compare方法的吧。如图中代码所示，对两个字符串进行比较时，会将字符串中的字符转换成统一的大小写进行比较，这样就达到了忽略大小写的功能。这...
SELECT CASE WHEN 'abc'='ABC' THEN 1 ELSE 0 END AS MATCHED FROM DUAL; Since Oracle compares the content and casing as well, it will return 0. We can ignore case and compare only content by altering user session by using NLS_COMP and NLS_SORT parameters. To set these parameters, we c...
首先说一下为什么要比较完大写还要比较小写：因为在某些字母里面，例如格鲁吉亚字母表，转换大写是无效的，...
