计算今天，本周，上个月的访问次数和总数[MySQL查询]

Question

大家好，这是我的表格的非常简化的版本：

我想对该表进行四个mysql查询。 所有这些都必须计算id_user等于某个特定值且类型不同于click的总访问次数。 一个查询必须计算今天的访问次数，另一个查询要计算本周的访问次数，月份和总访问次数。 我不是MySQL的专家，我当然可以使用PHP解决此问题，但我更喜欢将负载放在我的sql服务器上。 谢谢你的帮助！

Answer 1

放手去吧。 我不知道您的表格叫什么，所以我将其称为trafficTable ：

-- Visits today
select count(*) as visits_today
from trafficTable tt
where tt.type != 'click'
and tt.id_user = '19d71'
and datetime >= curdate();

-- Visits this week
select count(*) as visits_this_week
from trafficTable tt
where tt.type != 'click'
and tt.id_user = '19d71'
and yearweek(datetime) = yearweek(curdate());

-- Visits this month
select count(*) as visits_this_month
from trafficTable tt
where tt.type != 'click'
and tt.id_user = '19d71'
and year(datetime) = year(curdate())
and month(datetime) = month(curdate());

-- Total visits
select count(*) as total_visits
from trafficTable tt
where tt.type != 'click'
and tt.id_user = '19d71';

--- if you want the last month - this help other ppl in other thread
    select count(*) as visits_this_month
    from trafficTable tt
    where tt.type != 'click'
    and tt.id_user = '19d71'
    and year(datetime) <= year(curdate())
    and month(datetime) <= month(curdate());

您可能想看看这个页面：

函数month() ， date() ， curdate() ， week()和其他一些功能应该可以解决问题
