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："李"->l）,包括特殊字符处理，可以进行动态添加

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："李佳航"->ljh（或者说"张伟"-zw）)

        CREATE FUNCTION `pinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
BEGIN

    DECLARE V_RETURN VARCHAR(255);

    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));
