启动Mysql5.1x事件EVENT动态生成报表

最近有需求，更加基准表，每季度从基准表获得统计报表。
优点：实时，快速。减少程序带来的复杂。可维护性强，自动化。
要求：1定时。2报表
首先是确定启动Mysql EVENT： SET GLOBAL event_scheduler = 1;
第二定义EVENT：
CREATE EVENT myevent ON schedule every 10 second do
INSERT INTO dangfei (dyid,dangfei,dyname,djyear,jidu) SELECT id,jizhun,dyname,YEAR(curdate()),QUARTER(curdate()) FROM dangyuan;

CREATE  EVENT TOTAL_SEASON_EVENT  
  
ON SCHEDULE EVERY 1 QUARTER STARTS DATE_ADD(DATE_ADD(DATE( CONCAT(YEAR(CURDATE()),'-',ELT(QUARTER(CURDATE

()),3,6,9,12),'-',23)),INTERVAL 1 QUARTER),INTERVAL 1 HOUR)  
ON COMPLETION PRESERVE ENABLE  
DO
INSERT INTO dangfei (dyid,dangfei,dyname,djyear,jidu) SELECT id,jizhun,dyname,YEAR(curdate()),QUARTER(curdate()) FROM dangyuan;

从现在开始每隔九天定时执行
CREATE EVENT EVENT1

ON SCHEDULE EVERY 9 DAY STARTS NOW()
ON COMPLETION PRESERVE ENABLE
DO
BEGIN
   CALL TOTAL();
END




每个月的一号凌晨1 点执行
CREATE EVENT EVENT2  

ON SCHEDULE EVERY 1 MONTH STARTS DATE_ADD(DATE_ADD(DATE_SUB(CURDATE(),INTERVAL DAY(CURDATE())-1 DAY), INTERVAL 1 MONTH),INTERVAL 1 HOUR)
ON COMPLETION PRESERVE ENABLE
DO
BEGIN
    CALL STAT();
END



每个季度一号的凌晨2点执行

CREATE EVENT TOTAL_SEASON_EVENT

ON SCHEDULE EVERY 1 QUARTER STARTS DATE_ADD(DATE_ADD(DATE( CONCAT(YEAR(CURDATE()),'-',ELT(QUARTER(CURDATE()),1,4,7,10),'-',1)),INTERVAL 1 QUARTER),INTERVAL 2 HOUR)
ON COMPLETION PRESERVE ENABLE
DO
BEGIN
    CALL SEASON_STAT();
END




每年1月1号凌晨四点执行
CREATE EVENT TOTAL_YEAR_EVENT

ON SCHEDULE EVERY 1 YEAR STARTS DATE_ADD(DATE(CONCAT(YEAR(CURDATE()) + 1,'-',1,'-',1)),INTERVAL 4 HOUR)
ON COMPLETION PRESERVE ENABLE
DO
BEGIN
    CALL YEAR_STAT();
END
