1.手动建立一个分区

执行函数：
DROP PROCEDURE IF EXISTS `proc_create_partion_vehiclescores`;
DELIMITER ;;
CREATE DEFINER=`root`@`localhost` PROCEDURE `proc_create_partion_vehiclescores`()
BEGIN
/* 到系统表查出这个表的最大分区，得到最大分区的日期。在创建分区的时候，名称就以日期格式存放，方便后面维护 */
    SELECT REPLACE(partition_name,'p_vehiclescores','') INTO @P12_Name FROM INFORMATION_SCHEMA.PARTITIONS 
    WHERE table_name='vehiclescores' ORDER BY partition_ordinal_position DESC LIMIT 1;
     SET @Max_date= DATE(DATE_ADD(@P12_Name+0, INTERVAL 1 DAY))+0;
/* 修改表，在最大分区的后面增加一个分区，时间范围加1天 */
    SET @s1=CONCAT('ALTER TABLE vehiclescores ADD PARTITION (PARTITION p_vehiclescores',@Max_date,' VALUES LESS THAN (TO_DAYS (''',DATE(@Max_date),''')))');
    /* 输出查看增加分区语句*/
    SELECT @s1;
    PREPARE stmt2 FROM @s1;
    EXECUTE stmt2;
    DEALLOCATE PREPARE stmt2;
/* 取出最小的分区的名称，并删除掉 。
    注意：删除分区会同时删除分区内的数据，慎重 */
    /*select partition_name into @P0_Name from INFORMATION_SCHEMA.PARTITIONS 
    where table_name='tb_3a_huandan_detail' order by partition_ordinal_position limit 1;
    SET @s=concat('ALTER TABLE tb_3a_huandan_detail DROP PARTITION ',@P0_Name);
    PREPARE stmt1 FROM @s; 
    EXECUTE stmt1; 
    DEALLOCATE PREPARE stmt1; */
END
