mysql中文拼音排序实现方法

Jun 07, 2016 pm 05:51 PM

由于mysql对中文的支持不好,所以我们想要对中文进行按拼音排序也是一个不小不大的困难,今天我们利用convert函数来实现,不管什么编码都可以进行拼音进行排序哦,有需要的朋友参考一下。

对于包含中文的字段加上"binary"属性,使之作为二进制比较,例如将"name char(10)"改成"name char(10)binary"。
如果你使用编译MySQL,可以编译MySQL时使用 --with--charset=gbk 参数,这样MySQL就会直接支持中文查找和排序了(默认的是latin1)。也可以用 extra-charsets=gb2312,gbk 来加入多个字符集。
如果不想对表结构进行修改或者重新编译MySQL,也可以在查询语句的 order by 部分使用 CONVERT 函数。

比如

 代码如下 复制代码
* from mytable order by CONVERT(chineseColumnName USING gbk);

UTF8 默认校对集是 utf8_general_ci , 它不是按照中文来的。你需要强制让MySQL按中文来排序。

 代码如下 复制代码

select * from core_vender_info order by convert(vender_abbrev USING gbk) COLLATE gbk_chinese_ci


实例

 代码如下 复制代码
create table `test111cnnet` (                                
          `bid` int(4) unsigned not null auto_increment,      
          `namerean` varchar(20) character set gbk default null,
          primary key (`id`)                                
        ) ;

保存部份数据

 代码如下 复制代码

insert into `test1` (`id`, `namerean`) values('李');
insert into `test1` (`id`, `namerean`) values('邓');
insert into `test1` (`id`, `namerean`) values('站');

排序查询

 代码如下 复制代码

>select namerean fromtest111cnnetorder by namerean;

邓(d)
李(l)
站(z)

这样看上去mysql中文排序是没有任问题,因为我们的namerean是gbk编码,所以结果是满意的,那么如果是uft-8就不行了,所以我们构造了一条,

 代码如下 复制代码
select namerean from test111cnnet order by convert(namerean using gb2312) asc;

这样,不管当前字段为什么编码,他都能很好的按中文拼音进行排序
