Mysqlは日単位でテーブルパーティション化されます

1.データベース構造:テーブル名:income
id   income int_date
プライマリ・キー:id,int_date.int_を押すからdateパーティションなので、カラムのプライマリ・キーを追加する必要があります.
ストアド・プロシージャ:

DELIMITER $$
USE newdatabase$$

DROP PROCEDURE
IF EXISTS `create_Partition_income`$$

CREATE PROCEDURE `create_Partition_income`()label :
BEGIN
	/*     ，          ，                 。         23   ，Vlaue in    list  Rang less than*/
