通过oracle的NLSSORT函数对汉字按照拼音排序,然后根据汉字的区间返回对应的首字母. 效果1,获取拼音简码: 效果2,获取姓名首字母: 创建函数: /* 获取拼音简码函数 */ CREATE OR REPLACE FUNCTION GET_PYJM (P_NAME IN VARCHAR2) RETURN VARCHAR2 AS V_COMPARE ); V_RETURN ); BEGIN DECLARE FUNCTION F_NLSSORT (P_WORD IN VARCHAR2) RE
select * FROM organ_new where city_code = 'SZ0755' and organ_type = 'H' and state = '1' ORDER BY FIELD(organ_category,'三级','二级','一级') ,#自定义排序 CONVERT(organ_name USING gbk) COLLATE #中文首字母排序 gbk_chinese_ci DESC
有一个person对象如下: public class Person { private String id;private String nam; } 一个list集合如下: List<Employee> personList= Arrays.asList( new Person("1",“张小同"), new Person("2",”靖大同"), new Person("3",”王五"), new P
1.对判断的字段进行拆分 select substr(要区分的字段,0,1) from 表 : 得到一个 首字母 2.对这个字符进行大小写判断 查出以小写字符为开头的 select substr(要区分的字段,0,1) from 表 where substr(要区分的字段,0,1)=lower((substr(要区分的字段,0,1) )) ; 查出以小写字符为开头的 select substr(要区分的字段,0,1) from 表 where substr(要区分的字段,0,
public class ABD { public static void main(String[] args) { //Collator类是用来执行区分语言环境的String比较的,这里是选择CHINA Comparator comparator = Collator.getInstance(Locale.CHINA); String[] a = {"乔飞", "687","乔巴", "路飞","Cat"
CREATE OR REPLACE FUNCTION F_TRANS_PINYIN_CAPITAL(P_NAME IN VARCHAR2) RETURN VARCHAR2 AS V_COMPARE VARCHAR2(); V_RETURN VARCHAR2(); FUNCTION F_NLSSORT(P_WORD IN VARCHAR2) RETURN VARCHAR2 AS BEGIN RETURN NLSSORT(P_WORD, 'NLS_SORT=SCHINESE_PINYIN_M');
Java 字符串数组首字母排序 字符串数组按首字母排序:(区分大小写) String[] strings = new String[]{"ba","aa","CC","Ba","DD","ee","dd"}; Arrays.sort(strings); for (int i = 0; i < strings.length; i++) { System.out.p
