mysql用视图和事件实现数据间隔插入数据到表

创建视图

创建表

CREATE TABLE `getPerfdata` (
  `NO` bigint(20) NOT NULL AUTO_INCREMENT,
  `hostname` varchar(255) DEFAULT NULL,
  `servicename` varchar(255) DEFAULT NULL,
  `timeline` datetime DEFAULT NULL,
  `perfkey` varchar(255) DEFAULT NULL,
  `perfvalue` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`NO`),
  KEY `NO` (`NO`)
) ENGINE=InnoDB AUTO_INCREMENT=16739 DEFAULT CHARSET=utf8;

打开全局事件调度

mysql> set global event_scheduler=on;
Query OK, 0 rows affected (0.00 sec)

mysql> select @@event_scheduler;
+-------------------+
| @@event_scheduler |
+-------------------+
| ON                |
+-------------------+
1 row in set (0.00 sec

　　

创建事件实现视图数据按照计划插入表

CREATE DEFINER = `root`@`192.168.*.*` EVENT `insertPerfdata` ON SCHEDULE EVERY 6 MINUTE STARTS '2019-01-29 11:24:16' ON COMPLETION PRESERVE ENABLE DO
	INSERT INTO nagios.getPerfdata (
		hostname,
		servicename,
		timeline,
		perfkey,
		perfvalue
	) SELECT
		*
	FROM
		nagios.perfdata
