mysql 汉字按拼音字母排序获取拼音首字母拼音全拼

Posted 2021-02-19 毁乐乖狂，自有诪张

一、汉字utf-8 转gbk排序

 

ORDER BY  CONVERT(city_name USING gbk)

 

二、获取词语拼音首字母

创建函数

CREATE FUNCTION `firstPinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
BEGIN
    DECLARE V_RETURN VARCHAR(255);
    SET V_RETURN = ELT(INTERVAL(CONV(HEX(left(CONVERT(P_NAME USING gbk),1)),16,10), 
        0xB0A1,0xB0C5,0xB2C1,0xB4EE,0xB6EA,0xB7A2,0xB8C1,0xB9FE,0xBBF7, 
        0xBFA6,0xC0AC,0xC2E8,0xC4C3,0xC5B6,0xC5BE,0xC6DA,0xC8BB,
        0xC8F6,0xCBFA,0xCDDA,0xCEF4,0xD1B9,0xD4D1),    
    ‘A‘,‘B‘,‘C‘,‘D‘,‘E‘,‘F‘,‘G‘,‘H‘,‘J‘,‘K‘,‘L‘,‘M‘,‘N‘,‘O‘,‘P‘,‘Q‘,‘R‘,‘S‘,‘T‘,‘W‘,‘X‘,‘Y‘,‘Z‘);
    RETURN V_RETURN;
END

 

 

三、获取词语拼音

 

创建字典表

CREATE TABLE IF NOT EXISTS `tbl_dict_pinyin` (
  `pin_yin` varchar(255) CHARACTER SET gbk NOT NULL,
  `code` int(11) NOT NULL,
  PRIMARY KEY (`code_`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

 

插入字典数据

 

INSERT INTO tbl_dict_pinyin VALUES ("a", 20319), ("ai", 20317), ("an", 20304), ("ang", 20295), ("ao", 20292), ("ba", 20283), ("bai", 20265), ("ban", 20257), ("bang", 20242), ("bao", 20230), ("bei",
