MySQL - multiple count, min, max query - mysql

Question

SELECT
`name`, count(`cid`) AS count, Min(`price-3`) AS min, Max(`price-3`) AS max
FROM ed_prices
WHERE type="M"
GROUP BY cid, type
This query gives me what I want for type M. But I have 4 different types like M and a result for every one of them is necessary. While this query gives me a result like this:
name, count, min, max
I need a result like this:
name, countM, minM, maxM, countP, minP, maxP, countZ, minZ, maxZ ...
How can I achieve this?

I know this is not exactly what you're looking for but could you maybe work with this:
SELECT `name`
, type -- you'll want to include the type for each line item
-- to be able to identify which type the values refer to
, count(`cid`) AS count
, Min(`price-3`) AS min
, Max(`price-3`) AS max
FROM ed_prices
WHERE type IN ("M","P","Z","Q") -- where M, P, Z, Q are the different product types
GROUP BY cid, type
You could also try a self join on this to combine the results into one line, to get the results as you requested in the question but it is less scalable for anything more than a handful of products..
SELECT `name`
, countM
, minM
, maxM
, countZ
, minZ
, maxZ
, countP
, minP
, maxP
, countQ
, minQ
, maxQ
FROM
(SELECT `name`
, count(`cid`) AS countM
, Min(`price-3`) AS minM
, Max(`price-3`) AS maxM
FROM ed_prices
WHERE type = "M"
GROUP BY cid) MType
INNER JOIN
(SELECT `name`
, count(`cid`) AS countP
, Min(`price-3`) AS minP
, Max(`price-3`) AS maxP
FROM ed_prices
WHERE type = "P"
GROUP BY cid) PType ON MType.`name` = PType.`name`
INNER JOIN
(SELECT `name`
, count(`cid`) AS countZ
, Min(`price-3`) AS minZ
, Max(`price-3`) AS maxZ
FROM ed_prices
WHERE type = "Z"
GROUP BY cid) ZType ON MType.`name` = ZType.`name`
INNER JOIN
(SELECT `name`
, count(`cid`) AS countQ
, Min(`price-3`) AS minQ
, Max(`price-3`) AS maxQ
FROM ed_prices
WHERE type = "Q"
GROUP BY cid) QType ON MType.`name` = QType.`name`
