尝试SQL: 统计每天每个类型操作个用多少用户
select *
from (select trunc(created_time), action_type, user_id
from t_shq_task_operate_log l
where l.created_time > trunc(sysdate - 7)
and l.created_time < trunc(sysdate)
and l.action_type in (0, 1, 2, 3, 4)) pivot(count(distinct user_id) for action_type in (0,1, 2, 3, 4));
