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

CREATE FUNCTION `fristPinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8BEGIN    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

二.pinyin ：此函數是將一個中文字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 utf8BEGIN    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
