MySql每月增加一个分区以及查询所有分区

create PROCEDURE Usp_Partition()

BEGIN

DECLARE _time datetime;

DECLARE num int;

DECLARE _p VARCHAR(20)DEFAULT p;

DECLARE p1 VARCHAR(20);

/* 获取下一个月的第一天*/

select date_add(curdate()-day(curdate())+1,interval 1 month)as _time;

/*将时间中的‘-’去掉*/

SELECT REPLACE(_time,'-','')as num;

SELECT _p+num as p1;

 

 SET concat('alter table book8 ADD PARTITION (PARTITION p',p1,' VALUES LESS THAN (TO_DAYS (''',YEARWEEK(p1),''')))');

END

查询所有分区

select 

  partition_name part,  

  partition_expression expr,  

  partition_description descr,  

  table_rows  

from information_schema.partitions  where 

  table_schema = schema()  

  and table_name='book9';
