FROM sugon_jzg_jbxx b
where not exists (select 1 from user_role a where a.user_id=b.zgh)
檢視event是否開啟
show variables like '%sche%';
將事件計劃開啟
set global event_scheduler=1;
建立儲存過程add_user_role
CREATE PROCEDURE add_user_role()

zgh as user_id,
126 as role_id,
2 as type,
0 as is_del
FROM sugon_jzg_jbxx b
where not exists (select 1 from user_role a where a.user_id=b.zgh);
END;
每天定時執行任務，設定第一次執行時間為'2018-11-15 03:00:00'，並且每天執行一次
create event if not exists e_add_user_role
on schedule every 1 day starts '2018-11-15 03:00:00'
