MySQL中文轉換成拼音的函數

也是頭一次看到關於在mysql中直接把中文自動轉換成拼音兩個例子,看上去非常的好用我整理一下與大家分享,希望文章給大家有幫助。

漢字轉拼音全拼

 代碼如下 復制代碼

-- 創建漢字拼音對照臨時表
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;

例子2 中文漢字轉拼音函數

fristPinyin : 此函數是將一個中文字符串的第一個漢字轉成拼音字母 (例如:"中國人"->Z)

 代碼如下 復制代碼

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 :此函數是將一個中文字符串對應拼音母的每個相連 (例如:"中國人"->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;
