MySQL中文转换成拼音的函数

发布时间：01/15 来源：浏览：关键词：

也是头一次看到关于在mysql中直接把中文自动转换成拼音两个例子，看上去非常的好用我整理一下与大家分享，希望文章给大家有帮助。

汉字转拼音全拼

代码如下

-- 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;
-- 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", 20242),("bao",

例子2 中文汉字转拼音函数

fristPinyin ：此函数是将一个中文字符串的第一个汉字转成拼音字母（例如："中国人"->Z）

代码如下

CREATE FUNCTION `fristPinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
BEGIN
    DECLARE V_RETURN VARCHAR(255);
    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');
    RETURN V_RETURN;
END
pinyin ：此函数是将一个中文字符串对应拼音母的每个相连 (例如："中国人"->ZGR)

CREATE FUNCTION `pinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
BEGIN
    DECLARE V_COMPARE VARCHAR(255);
    DECLARE V_RETURN VARCHAR(255);
    DECLARE I INT;

    SET I = 1;
    SET V_RETURN = '';
    while I < LENGTH(P_NAME) do
        SET V_COMPARE = SUBSTR(P_NAME, I, 1);
        IF (V_COMPARE != '') THEN
            #SET V_RETURN = CONCAT(V_RETURN, ',', V_COMPARE);
            SET V_RETURN = CONCAT(V_RETURN, fristPinyin(V_COMPARE));
            #SET V_RETURN = fristPinyin(V_COMPARE);
        END IF;
        SET I = I + 1;
    end while;

    IF (ISNULL(V_RETURN) or V_RETURN = '') THEN
        SET V_RETURN = P_NAME;
    END IF;

RETURN V_RETURN;
END
