Mysql 汉字+英文字母拼音排序

–编码转换

select t.real_name from tb_common_user t where t.real_name is not null order by CONVERT(t.real_name USING gbk)

–非汉字

select * from tb_common_user where ascii(real_name)<127

第一种方式：

–编码转换

select t.real_name from tb_common_user t where t.real_name is not null order by CONVERT(t.real_name USING gbk)

缺点：对于纯英文字母无法 按照a b c 排序

第二种方式 :借助中间表 tb_coslers (在原有的基础上 增加了 小写a-z 和 A-Z 的转换) 解决了 第一种出现的问题.

示例：

SELECT t1.id, t1.name, t2.f_PY

FROM t_user t1, tb_coslers t2

WHERE CONV(HEX(LEFT(CONVERT(t1.name USING gbk ), 1)), 16, 10) BETWEEN t2.cBegin AND t2.cEnd

ORDER BY convert(t1.name using gbk) ASC

但是对于如下汉字 会超出限制 导致个别无法精确排序

—十六位进制 超过限制 如: 妞 嗯

select CONV(HEX(LEFT(CONVERT(t1.real_name USING gbk ), 1)), 16, 10) from tb_common_user t1 where real_name = ‘妞’;

备注：最好的方式是在数据库增加一个拼音字段。存字段的时候 把拼音也存进去

tb_coslers表：

–id 1-23 针对汉字

–id 34-59 针对大写英文字母

–id 60-85 针对小写英文字母
