This is what I have at the moment.
$db =& JFactory::getDBO();
$query = $db->getQuery(true);
$query->select('`#__catalog_commit`.`id` as id, `#__catalog_commit`.`date` as date, COUNT(`#__catalog_commit_message`.`commit_id`) as count,
(SELECT COUNT(`#__catalog_commit_message`.`type`) as count_notice FROM `#__catalog_commit_message` WHERE `#__catalog_commit_message`.`type` = 1 GROUP BY `#__catalog_commit_message`.`type`) as count_notice,
(SELECT COUNT(`#__catalog_commit_message`.`type`) as count_warning FROM `#__catalog_commit_message` WHERE `#__catalog_commit_message`.`type` = 2 GROUP BY `#__catalog_commit_message`.`type`) as count_warning,
(SELECT COUNT(`#__catalog_commit_message`.`type`) as count_error FROM `#__catalog_commit_message` WHERE `#__catalog_commit_message`.`type` = 3 GROUP BY `#__catalog_commit_message`.`type`) as count_error');
$query->from('#__catalog_commit_message');
$query->leftjoin('`#__catalog_commit` ON `#__catalog_commit`.`id` = `#__catalog_commit_message`.`commit_id`');
$query->group('`#__catalog_commit_message`.`commit_id`');
$query->order('`#__catalog_commit`.`id` DESC');
What I have is 2 tables with the following structures:
catalog_commit
==============
id
date
catalog_commit_message
======================
id
commit_id
type
message
Basically I want to have the count of each different types of messages per group items. In what I have it actually select every rows (Which is normal) but I'm looking for a way (nicier if possible) to have the count per messages type within the query.
EDIT: Just wanted to add that it's a JModelList.
From what I gather, this should be your query:
SELECT c.id
,c.date
,count(cm.commit_id) as ct_total
,sum(CASE WHEN cm.type = 1 THEN 1 ELSE 0 END) AS count_notice
,sum(CASE WHEN cm.type = 2 THEN 1 ELSE 0 END) AS count_warning
,sum(CASE WHEN cm.type = 3 THEN 1 ELSE 0 END) AS count_error
FROM catalog_commit c
LEFT JOIN catalog_commit_message cm ON cm.commit_id = c.id
GROUP BY c.id, c.date
ORDER BY c.id DESC
You had the order of your tables reversed in the LEFT JOIN. Also, you had weird subqueries in the SELECT list.

Dears,
I tried to create a view that sumarize transaction per category (row) and months (columns) on one year as this :
SELECT counterpart.id_category as catid, category AS Category, (
SELECT COALESCE(SUM(amount), 0)
FROM transaction
INNER JOIN counterpart
ON transaction.id_counterpart = counterpart.id_counterpart
WHERE YEAR(date) = YEAR(now())
AND MONTH(date) = 1
AND id_category = catid
) AS Jan, [...]
FROM transaction
INNER JOIN counterpart
ON transaction.id_counterpart = counterpart.id_counterpart
INNER JOIN category
ON counterpart.id_category = category.id_category
WHERE transaction.id_user = 2
AND YEAR(date) = YEAR(now())
GROUP BY category
I don't know if it's a good way or not, at least it works as single command but not as view.
On view, the WHERE id_category = catid for subquery doesn't work properly.
Thank you.
I suspect conditional aggregation would be more appropriate and quicker than a lot of sub queries.
for example
SELECT counterpart.id_category as catid, category AS Category,
sum(case when month(date) = 1 then 1 else 0 end) as Jan,
sum(case when month(date) = 2 then 1 else 0 end) as feb,
sum(case when month(date) = 3 then 1 else 0 end) as Mar
FROM transaction
INNER JOIN counterpart
ON transaction.id_counterpart = counterpart.id_counterpart
INNER JOIN category
ON counterpart.id_category = category.id_category
WHERE transaction.id_user = 2
AND YEAR(date) = YEAR(now())
GROUP BY counterpart.id_category,category
In my current query:
SELECT COUNT(WC.ID) AS "Regions"
FROM WHOLE_FEATURES_PDB_CHAINS AS WC
;
I COUNT(WC.ID) AS "Regions" .
However, we have multiple regions with WC.Type can be 1,2,3,4. I need to count each type occurrence into COUNT(WC.ID) AS "Region_1", COUNT(WC.ID) AS "Region_2" ... depending on WC.Type.
Is there any way to solve this in one query? I am looking at MySQL IF, yet do not know how to integrate it into the count function.
I need it to be in one row (the shown query here is reduced, it's a larger query)
SELECT COUNT(WC.ID) AS "Region_1" , COUNT(WC.ID) AS "Region_2" ...
Here is the complete query if anyone is interested:
SELECT PCS.PDB_id, PCS.Chain, PPA.ENSEMBL_start, PPA.ENSEMBL_end, PPA.eValue, PIN.TITLE AS "pdbTitle", COUNT(WC.ID) AS "Regions"
FROM PDB_Chains AS PCS
LEFT JOIN WHOLE_FEATURES_PDB_CHAINS AS WC ON WC.PDB_CHAIN_ID = PCS.idPDB_chains, PDB_protein_alignment PPA, PDB_INFOS PIN
WHERE PCS.idPDB_chains = PPA.idPDB_Chains
AND PCS.PDB_id = PIN.PDB_ID
AND PPA.idProteins = (SELECT idProteins from Proteins WHERE ENSEMBL_protein_id = "'+submittedID+'")
GROUP BY PCS.PDB_id, PCS.Chain ORDER BY PCS.PDB_id;
Here's the working solutin based on your kind answers
SELECT PIN.TITLE AS "pdbTitle", COUNT(CASE WHEN WC.STRUCTURAL_FEATURES_ID = 1 then 1 end) AS "PPInterface" , COUNT(CASE WHEN WC.STRUCTURAL_FEATURES_ID = 4 then 1 end) AS "flexibleRegions"
FROM PDB_Chains AS PCS LEFT JOIN WHOLE_FEATURES_PDB_CHAINS AS WC ON WC.PDB_CHAIN_ID = PCS.idPDB_chains, PDB_protein_alignment PPA, PDB_INFOS PIN
WHERE PCS.idPDB_chains = PPA.idPDB_Chains
AND PCS.PDB_id = PIN.PDB_ID
AND PPA.idProteins = (SELECT idProteins from Proteins WHERE ENSEMBL_protein_id = "ENSP00000256078.4")
GROUP BY PCS.PDB_id, PCS.Chain ORDER BY PCS.PDB_id;
You can use case when statement inside your aggregate function.
Try this .
count(case when WC.type = 1 then 1 end) as region_1, similarly repeat for another column.
Select
...
...
sum(if WC.ID = 1 then 1 else 0) as Region1,
sum(if WC.ID = 2 then 1 else 0) as Region2,
sum(if WC.ID = 3 then 1 else 0) as Region3,
sum(if WC.ID = 4 then 1 else 0) as Region4
Might do what you want.
You can use GROUP BY with COUNT to get the required result, e.g.:
SELECT WC.Type, COUNT(WC.ID) AS "Regions"
FROM WHOLE_FEATURES_PDB_CHAINS AS WC
GROUP BY WC.Type;
Update
If you want the counts as pivoted column for each region then you can write inner SELECT queries, e.g.:
SELECT
(SELECT COUNT(ID) FROM WHOLE_FEATURES_PDB_CHAINS WHERE type = 1) AS "Region_1",
(SELECT COUNT(ID) FROM WHOLE_FEATURES_PDB_CHAINS WHERE type = 2) AS "Region_2",
other_column
FROM WHOLE_FEATURES_PDB_CHAINS AS WC
WHERE <some condition>;
I have Php program that outputs names with the corresponding events attended and the number of times each event was attended over a period of time. As an example of the output
Name | Run | Swim | Bike | Total
John 3 2 5 10
MySQL query look something like this:
$sql = 'SELECT
e.name as Leader,
SUM(CASE WHEN c.catid = 26 THEN 1 ELSE null END) as "Swim",
SUM(CASE WHEN c.catid = 25 THEN 1 ELSE null END) as "Bike",
SUM(CASE WHEN c.catid = 24 THEN 1 ELSE null END) as "Run",
COUNT("Swim"+"Bike"+"Run") as total
FROM
events as e
LEFT JOIN event_categories as c ON c.uid = e.uid
WHERE
(DATE(e.event_start) BETWEEN "'.$from_date.'" and "'.$to_date.'")
GROUP BY Leader WITH ROLLUP;';
This works well, however, if I want to sort my data by "total" in descending order I get no output if I replace the last GROUP BY line with the following:
GROUP BY total DESC, Leader WITH ROLLUP;';
so that I get a listing with names who have the highest totals to the lowest, and people with the same totals get listed in alphabetical order. What am I doing wrong?
As mentioned in the comments, the ORDER BY and ROLLUP can not be used together. It states this here (http://dev.mysql.com/doc/refman/5.0/en/group-by-modifiers.html) about half way down the page. To get around this, you'll have to do the ORDER BY in another query where your original query acts as the subquery:
SELECT *
FROM
(
SELECT
e.name as Leader,
SUM(CASE WHEN c.catid = 26 THEN 1 ELSE null END) as "Swim",
SUM(CASE WHEN c.catid = 25 THEN 1 ELSE null END) as "Bike",
SUM(CASE WHEN c.catid = 24 THEN 1 ELSE null END) as "Run",
COUNT("Swim"+"Bike"+"Run") as total
FROM
events as e
LEFT JOIN event_categories as c ON c.uid = e.uid
WHERE
(DATE(e.event_start) BETWEEN "'.$from_date.'" and "'.$to_date.'")
GROUP BY Leader WITH ROLLUP
) as rolldup
ORDER BY Total DESC
ORIGINAL (WRONG) ANSWER:
You do not put Sorts in a GROUP BY clause. You put them in your ORDER BY clause:
$sql = 'SELECT
e.name as Leader,
SUM(CASE WHEN c.catid = 26 THEN 1 ELSE null END) as "Swim",
SUM(CASE WHEN c.catid = 25 THEN 1 ELSE null END) as "Bike",
SUM(CASE WHEN c.catid = 24 THEN 1 ELSE null END) as "Run",
COUNT("Swim"+"Bike"+"Run") as total
FROM
events as e
LEFT JOIN event_categories as c ON c.uid = e.uid
WHERE
(DATE(e.event_start) BETWEEN "'.$from_date.'" and "'.$to_date.'")
GROUP BY Leader WITH ROLLUP
ORDER BY total DESC;';
You don't want to GROUP BY Total you just want to ORDER BY total.
So the two last lines of your query should be
GROUP BY Leader WITH ROLLUP
ORDER BY total DESC
I have a table where I keep messages and one where I keep users.
I want to get all the users that interactioned (send or received a message) with user_id 1.
This query works:
http://sqlfiddle.com/#!2/6a2f3/1
EDIT:
SELECT DISTINCT
(CASE WHEN `user_to_id` = 1 THEN `user_from_id` ELSE `user_to_id` END) `user_id`,
users.*
FROM `messages`
INNER JOIN users
ON (CASE WHEN `user_to_id` = 1 THEN `user_from_id` ELSE `user_to_id` END) = users.user_id
WHERE `user_to_id` = 1 OR `user_from_id` = 1
ORDER BY `time` DESC
But if I add to SELECT the message column, it returns duplicate records:
http://sqlfiddle.com/#!2/6a2f3/2
EDIT:
SELECT DISTINCT
(CASE WHEN `user_to_id` = 1 THEN `user_from_id` ELSE `user_to_id` END) `user_id`,
`messages`.`message`,
users.*
FROM `messages`
INNER JOIN users
ON (CASE WHEN `user_to_id` = 1 THEN `user_from_id` ELSE `user_to_id` END) = users.user_id
WHERE `user_to_id` = 1 OR `user_from_id` = 1
ORDER BY `time` DESC
How can I fix that?
And also, I see that it orders the results after the "DISTINCT" selection was made. The first query should return the results inverted because the row with message_id 2 has time 3.
Is there a way I can order them before the "DISTINCT"?
EDIT 2: I wasn't clear about the question. I want to select only the last message for a matched user_id.
Do you want something like this?
SELECT *
FROM (
SELECT
users.*,
(SELECT `message` from messages
WHERE
(CASE WHEN `user_to_id` = 1 THEN `user_from_id` ELSE `user_to_id` END) = users.user_id
AND (`user_to_id` = 1 OR `user_from_id` = 1)
ORDER BY `time` DESC limit 1
) AS message
FROM users
) a
WHERE message IS NOT NULL
SQL Fiddle
It's not returning duplicate records, you have two records with User_ID = 2.
I'm confused by what you want them to be ordered by. If you want to order them in the inverted order, just remove 'DESC'
I have a select statement with a order by command. Now the order by command has a case statment based on the status of the record it sort by a different column. However, I need to also the order by DESC if the status = 1 else order by ASC.
How can I do this?
This is my current statement:
SELECT ph.phone_call_id AS id, ph.call_subject AS callSubject,
ph.trigger_on AS triggerOn,
ph.isAppointment,
IFNULL(ph.last_attempt_on, "") last_attempt_on,
ind.name AS industry,
ac.account_id,
ac.account_name AS accountName
FROM phone_calls AS ph
INNER JOIN accounts AS ac ON ph.account_id = ac.account_id
INNER JOIN industries AS ind ON ind.industry_id = ac.industry_id
INNER JOIN call_codes AS cc ON ph.call_code_id = cc.call_code_id
WHERE ac.status = 1
AND ph.status = '.$call_status.'
AND ph.owner_id = '. USER_ID .'
AND ac.do_not_call = 0
ORDER BY CASE WHEN ph.status = 1 THEN ph.trigger_on ELSE ph.last_attempt_on END
Is this what you want?
ORDER BY (CASE WHEN ph.status = 1 THEN ph.trigger_on end) DESC,
(case when ph.status <> 1 then ph.last_attempt_on END) ASC
