数据插入不覆盖更新
INSERT INTO user_role(
user_id,
role_id,
type,
is_del
)SELECT
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)
 
查看event是否开启
show variables like '%sche%';
 
将事件计划开启
set global event_scheduler=1;
 
创建存储过程add_user_role
CREATE PROCEDURE add_user_role()
BEGIN
INSERT INTO user_role(
user_id,
role_id,
type,
is_del
)SELECT
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;
