这篇文章主要介绍了Mysql中文汉字转拼音的实现,并且每个汉字会转换全拼,使用Mysql自定义函数实现,需要的朋友可以参考下
第一步：我们将在mysql中新建必要的函数
一、创建拼音对照表
-- 创建汉字拼音对照临时表
CREATE TABLE IF NOT EXISTS `t_base_pinyin` (
`pin_yin_` varchar(255) CHARACTER SET gbk NOT
NULL,
`code_` int(11) NOT NULL,
PRIMARY KEY (`code_`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
二、插入对照数据
-- 插入数据
INSERT INTO t_base_pinyin (pin_yin_,code_)VALUES
("a", 20319),("ai", 20317),("an", 20304),("ang", 20295),("ao",
20292),("ba", 20283),("bai", 20265),("ban", 20257),("bang",

10262),("zui", 10260),("zun", 10256),("zuo", 10254);
三、创建汉字转换拼音函数
-- 建立汉字转换拼音函数
DROP FUNCTION IF EXISTS to_pinyin;
DELIMITER $
CREATE FUNCTION to_pinyin(NAME VARCHAR(255) CHARSET gbk)
RETURNS VARCHAR(255) CHARSET gbk
BEGIN
DECLARE
mycode INT;
DECLARE
tmp_lcode VARCHAR(2) CHARSET gbk;
DECLARE
lcode INT;
DECLARE
tmp_rcode VARCHAR(2) CHARSET gbk;
DECLARE
rcode INT;
DECLARE mypy
VARCHAR(255) CHARSET gbk DEFAULT '';
DECLARE lp
INT;
SET mycode =
0;
SET lp =
1;
SET NAME =
HEX(NAME);
WHILE lp
< LENGTH(NAME) DO
SET tmp_lcode = SUBSTRING(NAME, lp, 2);
SET lcode = CAST(ASCII(UNHEX(tmp_lcode)) AS
UNSIGNED);SET tmp_rcode = SUBSTRING(NAME, lp + 2, 2);
SET rcode = CAST(ASCII(UNHEX(tmp_rcode)) AS
UNSIGNED);IF lcode > 128 THEN
SET mycode =65536 - lcode * 256 - rcode ;
SELECT CONCAT(mypy,pin_yin_) INTO mypy FROM t_base_pinyin WHERE
CODE_ >= ABS(mycode) ORDER BY CODE_ ASC LIMIT 1;
SET lp = lp + 4;
ELSE
SET mypy = CONCAT(mypy,CHAR(CAST(ASCII(UNHEX(SUBSTRING(NAME, lp,
2))) AS UNSIGNED)));
SET lp = lp + 2;
END IF;
END
WHILE;
RETURN
LOWER(mypy);
END;
$
DELIMITER ;
四、使用方法
select to_pinyin('测试')
