Oracle中文转拼音函数

最近两个项目都提出从中文转拼音的需求。我以前的做法是：从微软拼音输入法导出字库，建立中文拼音对照表，然后写一个函数从对照表查拼音。这种方法虽然思路简单，但是返回拼音的错误率太高，而且对每个字都要去查一遍3万记录的对照表，效率也不高。
  这两天重新写了一个函数来完成此功能，该函数利用了Oracle提供的NLSSORT，具有以下特点：

1. 不需要中文字库
2. 与数据库字符集无关
3. 支持Oracle 9i 及以上版本
4. 根据参数可分别返回全拼小写、全拼大写、全拼首字母大写，首字母小写、首字母大写
5. 不考虑多音字拼音上下文语义的正确性
6. 在2G内存、XP、10.2.0.1 上对3万中文返回拼音用时1.2秒
