# 第二步，创建pinyin自定义函数 #

    						IF (V_FPinyin != '') THEN					
    							SET V_RETURN = CONCAT(V_RETURN, V_FPinyin);
    						END IF;
            END IF;
            SET I = I + 1;

        RETURN V_RETURN;

# 第三步，创建fristPinyin自定义函数 #

    BEGIN
        DECLARE V_RETURN VARCHAR(255);

# 第四步，拼写sql脚本 #

1.  先查询一下所有的数据。

SELECT
    	id,
    	user_id,
    	fans_phone_num,
    	share_id,
    	fans_name,
    	fans_alias,
    	address,
    	sex,
    	fans_photo_url,
    	`STATUS`,
    	create_time,
    	update_time
    FROM
    	dygafans_fans
    ORDER BY
    	CONVERT (fans_name USING gbk) ASC;

1.  在按照要求来查询一下

SELECT
    	id,
    	user_id,
    	fans_phone_num,
    	share_id,
    	fans_name,
    	LEFT (pinyin(fans_name), 1) AS firstName,
    	fans_alias,
    	address,
    	sex,
    	fans_photo_url,
    	`STATUS`,
    	create_time,
    	update_time
    FROM
    	dygafans_fans
    ORDER BY
    	CONVERT (fans_name USING gbk) ASC;

新增了一列`firstName`,按照拼音来排序。
