mysql查詢按照查詢名字拼音首字母排序

第一步，先創建一個表插入幾條數據

-- Table structure for dygafans_fans
-- ----------------------------
DROP TABLE IF EXISTS `dygafans_fans`;
CREATE TABLE `dygafans_fans` (
  `id` int(10) NOT NULL AUTO_INCREMENT COMMENT '主鍵id',
  `user_id` bigint(32) NOT NULL COMMENT '用戶id',

  `status` varchar(32) DEFAULT NULL COMMENT '狀態：1-開通，2-關閉',
  `create_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP COMMENT '創建時間',
  `update_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新時間',
  PRIMARY KEY (`id`) USING BTREE,
  UNIQUE KEY `fans_phone_num` (`fans_phone_num`,`share_id`) USING BTREE COMMENT '手機號，行業不能重複',
  KEY `ind_dygafansfans_userid` (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT='粉絲表';

-- ----------------------------
-- Records of dygafans_fans
-- ----------------------------
INSERT INTO `dygafans_fans` VALUES ('1', '1', '17112345454', '1', '二狗', '二狗', '農信大廈18樓', '0', 'http://192.168.130.132/file/group1/M00/00/0C/wKiCSV3oroSAORwRAAM61UUASNg722.jpg', '1', '2019-12-10 16:45:45', '2019-12-11 10:21:56');
INSERT INTO `dygafans_fans` VALUES ('2', '1', '17112345678', '2', '啊三', '張三', '農信大廈18樓', '0', 'http://192.168.130.132/file/group1/M00/00/0C/wKiCSV3oroSAORwRAAM61UUASNg721.jpg', '1', '2019-12-10 16:46:03', '2019-12-11 10:34:37');
INSERT INTO `dygafans_fans` VALUES ('3', '1', '17123455432', '2', '王五', '王五', '農信大廈19樓', '0', 'http://192.168.130.132/file/group1/M00/00/0C/wKiCSV3oroSAORwRAAM61UUASNg723.jpg', '1', '2019-12-10 16:46:49', '2019-12-10 16:46:55');
INSERT INTO `dygafans_fans` VALUES ('4', '1', '17123438907', '1', '李海吵', '醜比', '農信大廈20樓', '0', 'http://192.168.130.132/file/group1/M00/00/0C/wKiCSV3oroSAORwRAAM61UUASNg721.jpg', '1', '2019-12-11 10:42:27', '2019-12-11 10:42:27');

第二步，創建pinyin自定義函數

CREATE DEFINER=`root`@`%` FUNCTION `pinyin`(P_NAME VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
BEGIN
    DECLARE V_COMPARE VARCHAR(255);
    DECLARE V_RETURN VARCHAR(255);
		DECLARE V_FPinyin VARCHAR(2);
    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_FPinyin = fristPinyin(V_COMPARE);
						IF (V_FPinyin != '') THEN					
							SET V_RETURN = CONCAT(V_RETURN, V_FPinyin);
						END IF;
        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

第三步，創建fristPinyin自定義函數

CREATE DEFINER=`root`@`%` 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

全部創建好以後爲這樣

第四步，拼寫sql腳本

1. 先查詢一下所有的數據。

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;

2. 在按照要求來查詢一下

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,按照拼音來排序。
