关于mysql触发器或SP的问题
原始数据表：

现在这个sp或者触发器应该怎么做呢？
请高手能给出具体代码
[解决办法]
create TABLE t10( branch_id INT(11), flow_total INT(11), flow_free INT(11), flow_nofree INT(11) , effect_time datetime); insert into t10 values (1,256,128,128,'2010-09-10 00:00:00'), (1,1024,256,768,'2010-09-10 00:05:00'), (2,1024,256,768,'2010-09-10 00:00:00'), (2,1024,256,768,'2010-09-10 00:05:00'); select * from t10; # 日 select branch_id,sum(flow_total),sum(flow_free),sum(flow_nofree),date_format(effect_time,'%Y-%m-%d') from t10 group by branch_id,date_format(effect_time,'%Y-%m-%d')；# 周select branch_id,sum(flow_total),sum(flow_free),sum(flow_nofree),yearweek(effect_time) from t10 group by branch_id,yearweek(effect_time)；# 月select branch_id,sum(flow_total),sum(flow_free),sum(flow_nofree),date_format(effect_time,'%Y-%m') from t10 group by branch_id,date_format(effect_time,'%Y-%m')； # 年 select branch_id,sum(flow_total),sum(flow_free),sum(flow_nofree),date_format(effect_time,'%Y') from t10 group by branch_id,date_format(effect_time,'%Y')；
