定时建表

每天凌晨一点建一个第二天的表
DELIMITER //
CREATE PROCEDURE test.create_tab_every_day()
BEGIN
DECLARE `@i` VARCHAR(15);
DECLARE `@sqlstr` VARCHAR(2560);
SET `@i` = DATE_FORMAT(DATE_ADD(NOW(),INTERVAL 1 DAY),'%Y_%m_%d');
SET @sqlstr = CONCAT(
"CREATE TABLE day_tab_",
`@i`,
"(
  `prop` VARCHAR(40)
);"
);
PREPARE stmt FROM @sqlstr;
EXECUTE stmt;
END;

CALL test.create_tab_every_day();
/*****DROP PROCEDURE test.create_tab_every_day;*****/
/*****drop table test.day_tab_2015_09_11;*****/

DELIMITER $$
CREATE EVENT event_create_tab_days
ON SCHEDULE EVERY 1 DAY
STARTS '2015-09-10 01:00:00'
ON  COMPLETION  PRESERVE
ENABLE
DO
BEGIN
CALL test.create_tab_every_day();
END
$$
DELIMITER ;


每月的11号建一张下个月的表

DELIMITER //
CREATE PROCEDURE test.create_tab_every_mon()
BEGIN
DECLARE `@i` VARCHAR(15);
DECLARE `@sqlstr` VARCHAR(2560);
SET `@i` = DATE_FORMAT(DATE_ADD(NOW(),INTERVAL 1 MONTH),'%Y_%m');
SET @sqlstr = CONCAT(
"CREATE TABLE mon_tab_",
`@i`,
"(
  `prop` VARCHAR(40)
);"
);
PREPARE stmt FROM @sqlstr;
EXECUTE stmt;
END;


CALL test.create_tab_every_mon();
/*****DROP PROCEDURE test.create_tab_every_mon;*****/
/*****DROP TABLE test.mon_tab_2015_10*****/


DELIMITER $$
CREATE EVENT event_create_tab_mons
ON SCHEDULE EVERY 1 MONTH
STARTS '2015-09-11 01:00:00'
ON  COMPLETION  PRESERVE
ENABLE
DO
BEGIN
CALL test.create_tab_every_mon();
END
$$
DELIMITER ;
