How to use having condition in SQL query - sql

Question

SELECT
userid,
CASE
WHEN (COUNT(CASE
WHEN onlinesportsgamewagers != 0
THEN 1
ELSE null
END)
+ COUNT(CASE
WHEN depositmade_amt != 0
THEN 1
ELSE null
END)) >= 10
THEN "VIP"
ELSE "NON-VIP"
END as VIPcheck
FROM
player_activity
WHERE
userid = 2023410
GROUP BY
year(txndate), month(txndate)
This query determines the user's VIP status for each month.
Ultimately, I want to have a query that determines if the user achieved VIP status for at least 3 months (including the current month). For the time being, it's only user 2023410, but eventually I want to run this for the whole database.
Therefore my ultimate output would be:
User - VIPcheck (3 different months w/ active status)
(one row per userID)
HAVING COUNT(CASE WHEN (COUNT(CASE WHEN onlinesportsgamewagers != 0
THEN 1
ELSE null
END)
+ COUNT(CASE WHEN depositmade_amt != 0
THEN 1
ELSE null
END)) >= 10
THEN 1
ELSE 0
END)
Tried the above having statement, but it didn't work. Any suggestions?

Answer 1

If I understand correctly, this gets the VIP status for one user by month:
SELECT userid, year(txndate), month(txndate),
(CASE WHEN SUM(CASE WHEN onlinesportsgamewagers <> 0 THEN 1 ELSE 0 END) +
SUM(CASE WHEN depositmade_amt <> 0 THEN 1 ELSE 0 END) >= 10
THEN 'VIP'
ELSE 'NON-VIP'
END) as VIPcheck
FROM player_activity
GROUP BY userid, year(txndate), month(txndate);
Another aggregation will get what you want:
SELECT userid,
(CASE WHEN SUM(VIPcheck = 'VIP') >= 3 THEN 'SUPER-VIP'
WHEN SUM(VIPcheck = 'VIP') >= 1 THEN 'VIP'
ELSE 'HOI POLLOI'
END) as status
FROM (SELECT userid, year(txndate), month(txndate),
(CASE WHEN SUM(CASE WHEN onlinesportsgamewagers <> 0 THEN 1 ELSE 0 END) +
SUM(CASE WHEN depositmade_amt <> 0 THEN 1 ELSE 0 END) >= 10
THEN 'VIP'
ELSE 'NON-VIP'
END) as VIPcheck
FROM player_activity
GROUP BY userid, year(txndate), month(txndate)
) uym
GROUP BY userid;
