1、建表插入数据
CREATE TABLE `s1` (
 `id` int(11) NOT NULL DEFAULT '0' COMMENT '',
 `max` int(11) NOT NULL COMMENT ''
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;

insert into s1 values(1,999999);

2、创建函数
DELIMITER $$
CREATE DEFINER=`root`@`%` FUNCTION `nextTrxSerno`() RETURNS varchar(30) CHARSET utf8
BEGIN
DECLARE v_id INT (11) ;
DECLARE v_max INT (11) ;
DECLARE EXIT HANDLER FOR SQLEXCEPTION RETURN '' ;


UPDATE
s1 s SET
s.id = s.id + 1 ;


SELECT
s.id,
s.max INTO v_id,
v_max
FROM
s1 s ;


IF v_id >= v_max - 10 THEN SET v_id = 1 ; END IF ;


UPDATE
s1 s SET
s.id = v_id + 1 ;


RETURN CONCAT(DATE_FORMAT(SYSDATE(), '%Y%m%d%H%i%S'), LPAD(v_id, 8, '0')) ;


END $$
DELIMITER ;

3、调用函数
select nextTrxSerno();

4、查看结果：
主库：
mysql> select * from s1;
+----+--------+
| id | max    |
+----+--------+
|  3 | 999999 |
+----+--------+
1 row in set (0.00 sec)


备库：
mysql> select * from s1;
+----+--------+
| id | max    |
+----+--------+
|  1 | 999999 |
+----+--------+
1 row in set (0.00 sec)
