Mysql - Users Analysis with in a date range - php

Question

I've an activity tracker table with activity_id (Primary key, auto increment), user_id, api_function and date_added fields (please find the screenshot attached).
By using the below query I was able to count the number of entries per user in the last 28 days:
SELECT COUNT( DISTINCT date(date_Added) ) AS day_of_activity, user_id
FROM activity_tracker
WHERE date_added >= DATE( NOW() ) - INTERVAL 28 DAY
GROUP BY user_id
LIMIT 0 , 30
like:
days_of_activity user_id
34 1
1 3
13 9
2 10
1 11
8 12
I need to track the count of users who have:
more than 16 entries in the past 28 days
between 6 to 16 in the past 28 days,
1 to 6 in the past 28 days,
no entries in the past 30 days,
no entries in the past 90 days and
no entries in the past 180 days.
Is it possible to do this in single mysql query?
Please help me.
Thanks in advance.

Answer 1

Please find the answer below:
SELECT
SUM(
CASE WHEN day_of_activity>16 AND last_activity_date >= DATE(NOW()) - INTERVAL 28 DAY
THEN 1 ELSE 0
END)
as daily_users_count,
SUM(
CASE WHEN day_of_activity>6 AND day_of_activity <=16 AND last_activity_date >= DATE(NOW()) - INTERVAL 28 DAY
THEN 1 ELSE 0
END)
as weekly_users_count,
SUM(
CASE WHEN day_of_activity>=1 AND day_of_activity <=6 AND last_activity_date >= DATE(NOW()) - INTERVAL 28 DAY
THEN 1 ELSE 0
END)
as monthly_users_count,
SUM(
CASE WHEN DATE_SUB(CURDATE(),INTERVAL 30 DAY) >= last_activity_date OR last_activity_date IS NULL
THEN 1 ELSE 0
END)
as not_in_30,
SUM(
CASE WHEN DATE_SUB(CURDATE(),INTERVAL 90 DAY) >= last_activity_date OR last_activity_date IS NULL
THEN 1 ELSE 0
END)
as not_in_90,
SUM(
CASE WHEN DATE_SUB(CURDATE(),INTERVAL 180 DAY) >= last_activity_date OR last_activity_date IS NULL
THEN 1 ELSE 0
END)
as not_in_180
FROM (
SELECT COUNT(DISTINCT date(at.date_added)) as day_of_activity, a.user_id, max(at.date_added) as last_activity_date
FROM accounts a
LEFT JOIN activity_tracker at ON a.user_id = at.user_id
WHERE a.user_role_id = 2
GROUP BY a.user_id
)temp

Answer 2

try this query
select CASE WHEN dates_of_activity>16 THEN count(*) ELSE
CASE WHEN dates_of_activity>6 and dates_of_activity<17 THEN count(*) ELSE CASE WHEN dates_of_activity>0 and dates_of_activity<7 THEN count(*) ELSE count(*)
END
END END as count,
CASE WHEN dates_of_activity>16 THEN 'Above 16' ELSE
CASE WHEN dates_of_activity>6 and dates_of_activity<17 THEN ' >6 and<16' ELSE CASE WHEN dates_of_activity>0 and dates_of_activity<7 THEN '>0 and <6' ELSE 'never use'
END
END END as typeday
from (SELECT COUNT( DISTINCT date( date_Added ) ) AS dates_of_activity
, user_id
FROM activity_tracker
WHERE date_added >= DATE( NOW( ) ) - INTERVAL 28 DAY
GROUP BY user_id)a
LIMIT 0 , 30
