Compter les visites par aujourd'hui, cette semaine, le mois dernier et le total [requête MySQL]

Essayez-les. Je ne sais pas comment s'appelle votre table, je l'ai donc appelée 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());
