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'); |
排序查询
代码如下 | 复制代码 |
>select namerean fromtest111cnnetorder by namerean; 邓(d) |
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

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
