๐Ÿšจ SQL Challenge โ€” Real-World Use Case

Youโ€™re given a log table with 3 columns:
๐Ÿ“… record_date,
๐Ÿฆ account_id,
๐Ÿ‘ค user_id

Task:
๐Ÿ” For each account, identify users who came back after 7+ days of inactivity.

Sounds simple, right?
But to solve this, youโ€™ll need to:

* Use LAG() to compare login dates
* Calculate gaps between logins per user
* Filter only those who returned after 7+ days
* Do all of this per account, not globally

This is exactly the kind of logic youโ€™ll face in interviews and real projects.

Hereโ€™s the SQL solution ๐Ÿ‘‡

๐Ÿง  SQL Solution:


WITH user_logins AS (
SELECT
account_id,
user_id,
record_date,
LAG(record_date) OVER (
PARTITION BY account_id, user_id
ORDER BY record_date
) AS prev_login
FROM user_activity_log
),
login_gaps AS (
SELECT *,
DATEDIFF(day, prev_login, record_date) AS gap_days
FROM user_logins
)
SELECT DISTINCT
account_id,
user_id
FROM login_gaps
WHERE gap_days >= 7;
