Help with MySQL and CASE WHEN with a range of values
- by kickdaddy
I have an accounts table and a records table where accounts have multiple records. I would like to break down the account totals by "count of records" range. i.e. show the breakdown of
Count of Records | Count
0-25 | 100
25 - 50 | 122
50 - 100 | 300
etc.
I am using the following query, but I can't get it to group by "grp" which is what I want, any help on the best way to modify query? Thanks!
SELECT count(*) as ct,
CASE
WHEN COUNT(*) < 25 THEN '1-25'
WHEN COUNT(*) >= 25 < 50 THEN '25-50'
WHEN COUNT(*) >= 50 < 100 THEN '50-100'
WHEN COUNT(*) >= 100 < 250 THEN '100-250'
WHEN COUNT(*) >= 250 < 500 THEN '250-500'
WHEN COUNT(*) >= 500 < 1000 THEN '500-1000'
ELSE '1000+'
END AS grp
FROM records r,accounts a
WHERE r.account_id=a.id
ORDER BY ct
