Question

Okay, I have a single table like this:

id  query  results  ip
---------------------------------
1   milk   17       10.10.10.1
2   milk   17       10.10.10.1
3   milk   17       10.10.10.2
4   bread  8        10.10.10.2
5   bread  8        10.10.10.2
6   cheese 12       10.10.10.1

I have this query right now:

SELECT COUNT(DISTINCT(id)) as cnt, query, results, ip
FROM table
GROUP BY query
ORDER BY results ASC
LIMIT 20

This query returns these results:

count  query  results
---------------------
2      bread  8
1      cheese 12
3      milk   17

I need to expand on that query (or redo it completely) to return something like this, preferably with the IP’s in a nested array as part of the query’s array:

query  count  results  ip
--------------------------------
bread  2      8        10.10.10.2 (2)
cheese 1      12       10.10.10.1 (1)
milk   3      17       10.10.10.1 (2)
                       10.10.10.2 (1)

I’ll be outputting this with php, attaching the IP list with that count to the query count display (click to show/hide a modal with the info populated).

Any direction or help to get the data I need out would be wonderful!

Answer 1

The answer to this (despite numerous claims to the contrary) is “Yes you can, with a derived table”:

SELECT
  SUM(cnt) as cnt,
  query, results,
  GROUP_CONCAT(ip SEPARATOR '\n') AS ip
FROM (
  SELECT
    query, results,
    COUNT(DISTINCT(id)) as cnt,
    CONCAT(ip, '(', COUNT(ip), ')') AS ip
  FROM test
  GROUP BY query, ip
) t
GROUP BY query
ORDER BY results ASC
LIMIT 20

Sample…

The one thing you cannot do is have PHP understand that the value of ip is an array with no other interference. However, you could do this slightly nasty thing to dynamically construct the data into JSON, and then it can simply be passed to json_decode() in PHP to easily convert it to a PHP vector type.
