主要用于品牌排序,名字排序,地区排序等

第一种方法mysql函数

DELIMITER $$CREATE FUNCTION `fristPinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8  DETERMINISTICBEGIN     DECLARE V_RETURN VARCHAR(255);    DECLARE V_BOOL INT DEFAULT 0;          DECLARE FIRST_VARCHAR VARCHAR(1);     SET FIRST_VARCHAR = left(CONVERT(P_NAME USING gbk),1);    SELECT FIRST_VARCHAR REGEXP '[a-zA-Z]' INTO V_BOOL;    IF V_BOOL = 1 THEN      SET V_RETURN = FIRST_VARCHAR;    ELSE      SET V_RETURN = ELT(INTERVAL(CONV(HEX(left(CONVERT(P_NAME USING gbk),1)),16,10),             0xB0A1,0xB0C5,0xB2C1,0xB4EE,0xB6EA,0xB7A2,0xB8C1,0xB9FE,0xBBF7,             0xBFA6,0xC0AC,0xC2E8,0xC4C3,0xC5B6,0xC5BE,0xC6DA,0xC8BB,            0xC8F6,0xCBFA,0xCDDA,0xCEF4,0xD1B9,0xD4D1),         'A','B','C','D','E','F','G','H','J','K','L','M','N','O','P','Q','R','S','T','W','X','Y','Z');      END IF;    RETURN V_RETURN;END$$DELIMITER;

执行SQL

select intermediary_id, intermediary_name, fristPinyin(intermediary_name) as fristPinyinfrom t_second_agent_intermediarywhere city_id = 1337  and intermediary_type = 'zj'ORDER BY fristPinyin ;

第二种,直接sql语句查询

t_brand为品牌表

brand_ch_name品牌名称(需要排序的)

select  * from (select id,brand_ch_name,ELT(INTERVAL(CONV(HEX(left(CONVERT(brand_ch_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') as firstPinyin from t_brand ORDER BY firstPinyin ) t where     t.firstPinyin >= 'a' and t.firstPinyin <=  'c'
