获取汉字拼音首字母

获取汉字拼音首字母  获取汉字拼音首字母

很好用....觉的不错的帮顶!!!!!!!!!!!!!! 

1.下面的不上乱码是字节

--第一步建立一个函数
CREATE OR REPLACE FUNCTION F_TRANS_PINYIN_CAPITAL(P_NAME IN VARCHAR2) RETURN VARCHAR2 AS

BEGIN
RETURN NLSSORT(P_WORD, 'NLS_SORT=SCHINESE_PINYIN_M');
END;

END LOOP;
RETURN V_RETURN;

--第二步 执行下面语句更 改业务

update sdc_industrypartition set pinyin = F_TRANS_PINYIN_CAPITAL(industryname)

怎么是个jar包啊，能不能贴出源码来
