I want to concatenate and count data of the same column, so I can concatenate but I can not count the repeated data.
Here's my table of data:
| ID | bills | class |
|-----|-------|-------|
| 1 | 0.5 | 2 |
| 2 | 1 | 1 |
| 3 | 0.5 | 2 |
| 5 | 1 | 3 |
| 6 | 0 | 2 |
| 7 | 0.5 | 1 |
| 8 | 1 | 2 |
| 9 | 1 | 3 |
| 10 | 0.5 | 1 |
| 11 | 0 | 2 |
| 12 | 1 | 1 |
| 13 | 0 | 3 |
| 14 | 1 | 2 |
| 15 | 0 | 1 |
| 16 | 0 | 1 |
| 17 | 0.5 | 3 |
| 18 | 0 | 3 |
| 13 | 0.5 | 3 |
Here's my sql query I'm using to concatenate data:
SELECT class AS lesson,
GROUP_CONCAT( bills ORDER BY bills ) AS bills
FROM tb_presence
GROUP BY class;
Here's my result below:
| class | bills |
|-------|------------------|
| 1 | 1,0.5,0.5,1,0,0 |
| 2 | 0.5,0,1,0,1 |
| 3 | 1,1,0,0.5,0,0.5 |
Now I would like to count the data that are equal, but continue with the same concatenation.
I want to "count" the data with the same values and display concatenated (column observation and only to help understanding)
| class | bills | observation |
|-------|-------|-----------------------------|
| 1 | 2,2,2 | (2=0+0) (2=0.5+0.5) (2=1+1) |
| 2 | 2,1,2 | (2=0+0) (1=0.5) (2=1+1) |
| 3 | 2,2,2 | (2=0+0) (2=0.5+0.5) (2=1+1) |
Is this really possible?
Here is a solution (thanks to #wchiquito for the sqlfiddle) See http://sqlfiddle.com/#!2/2d2c8/1
As you can see it cannot dynamically determine the bills' values and count them. But there is a count per bill value that you want.
SELECT class AS lesson,
GROUP_CONCAT( bills ORDER BY bills ) AS bills
,SUM(IF(bills=0,1,0)) AS Count0
,SUM(IF(bills=0.5,1,0)) AS Count05
,SUM(IF(bills=1,1,0)) AS Count1
,COUNT(*) AS totalRecords
,COUNT(*)
- SUM(IF(bills=0,1,0))
- SUM(IF(bills=0.5,1,0))
- SUM(IF(bills=1,1,0))
AS Missing
FROM tb_presence GROUP BY class;
I added an extra record to show how the 'missing' column could show if you were not taking all values into consideration.
Results
| LESSON | BILLS | COUNT0 | COUNT05 | COUNT1 | TOTALRECORDS | MISSING |
|--------|-----------------------------------------|--------|---------|--------|--------------|---------|
| 1 | 0.00,0.00,0.50,0.50,1.00,1.00,1.00,4.00 | 2 | 2 | 3 | 8 | 1 |
| 2 | 0.00,0.00,0.50,0.50,1.00,1.00 | 2 | 2 | 2 | 6 | 0 |
| 3 | 0.00,0.00,0.50,0.50,1.00,1.00 | 2 | 2 | 2 | 6 | 0 |

I have 3 tables: shows, seasons and ratings. I would like to get average ratings of specific seasons and then make an average of this for every show and sort them by this value asc or desc. I was able to get this result by this raw query:
$shows = Show::selectRaw('shows.*, avg(x.seasons_avg_points) as ratings_avg_points')
->fromSub(function($query){
$query->selectRaw('shows.id, avg(ratings.points) as seasons_avg_points')
->from('shows')
->join('seasons', 'shows.id', '=', 'seasons.show_id')
->leftJoin('ratings', 'ratings.item_id', '=', 'seasons.item_id')
->groupBy('seasons.id');
}, 'x')
->join('shows', 'shows.id', '=', 'x.id')
->groupBy('x.id')
->get()->sortBy('shows_avg_points');
However I prefer to use Laravel eloquent functions so I tried also this:
$shows = Show::with(['seasons' => function($query){
$query->withAvg('ratings', 'points');
}])->withAvg('seasons', 'ratings_avg_points')->get();
Unfortunately, it only works without ->withAvg('seasons', 'ratings_avg_points'), as there can't be made an average of a computed column (ratings_avg_points) and it can't be found.

Is there a way I can get Show models with their average rating values without using that 'ugly' query above?
I am generating sequential reference numbers like complaint/1, complaint/2 when an insertion is made. I get what the previously generated value is (complaint/2) and then increment.
But when two users submit at the same time, I sometimes get same reference nos for both complaints.
How do I prevent this?

As mentioned in comments, just store an autoincrementing id. All the other stuff can be handled by trivial queries and/or your presentation layer.
By way of example...
DROP TABLE IF EXISTS my_table;
CREATE TABLE my_table
(id SERIAL PRIMARY KEY
,user INT NOT NULL
);
INSERT INTO my_table (user) VALUES
(1),(1),(3),(3),(5),(2),(1),(8),(4),(5),(7),(5),(5),(4),(1),(2),(3),(6),(4),(6),(1),(5),(1),(8);

could you pls help me. Thank you in advance.
Try this:
SELECT
roleID AS role,
GROUP_CONCAT(DISTINCT permID ORDER BY permID ASC SEPARATOR '|') AS permissions
FROM role_perm
GROUP BY roleID
ORDER BY roleID
I suppose you could do this with a nifty MySQL query as well (which would supposedly be better for performance), but since I'm not that good at SQL, here's the PHP solution:
$arrRoles = array();
while ($row = mysql_fetch_assoc($result)) {
if (!isset($arrRoles[$row['roleID']])) {
$arrRoles[$row['roleID']] = array();
}
$arrRoles[$row['roleID']][$row['permID']] = $row['value'];
}
var_dump($arrRoles);
I have a database table campaign_data. I need to select the customer_id where in the campaign there is difference in tariff. How can i do that with MySQL query. Here is some sample data.
SQL Fiddle Schema
| CAMPAIGN_ID | CUSTOMER_ID | CAMPAIGN_NAME | TARIFF |
---------------------------------------------------------
| 1 | 1 | Richmond | 100 |
| 2 | 1 | Sutton Coldfield | 75 |
| 3 | 1 | Putney | 100 |
| 4 | 1 | Kentish Town | 100 |
| 5 | 1 | Woking | 100 |
| 6 | 2 | Chiswick | 90 |
| 7 | 2 | Ealing | 100 |
| 8 | 2 | Camden | 100 |
| 9 | 3 | Croydon | 75 |
| 10 | 3 | Croydon1 | 100 |
| 11 | 3 | Archway | 100 |
| 12 | 4 | Ealing0 | 100 |
| 13 | 4 | Ealing01 | 100 |
| 14 | 4 | Ealing02 | 100 |
| 15 | 4 | Chingford | 100 |
| 16 | 4 | chingford01 | 100 |
Now as you can see customer id 1 , and 3 has different tariffs. I want to select them and leave the customer id 4 because it has campaigns with same tariffs.
Desired Output
| CUSTOMER_ID |
---------------
| 1 |
| 2 |
| 3 |
For clearification you can see customer 1 has 5 records. If in his 5 records the tariff is same (100) i want to avoid but if the tariff is not some as 4 records have 100 and one has 75, i want to select.
SELECT customer_id, count(DISTINCT tariff) as tariffs
FROM campaign_data
GROUP BY customer_id
HAVING tariffs > 1
you looking for this maybe
SELECT customer_id
FROM campaign_data
GROUP BY customer_id
HAVING count(DISTINCT tariff) > 1
http://sqlfiddle.com/#!2/48b6e/31
select
customer_id,
tariff
from campaign_data
group by customer_id
having sum(tariff)/count(tariff) <> tariff;
Would like to get the following as a result from the table structure below (MYSQL + PHP)

The problem I have with a simple SELECT, JOIN and GROUP_CONCAT is that the values duplicate after selecting all the images.
I've tried various other ways for example selecting the data by row combined with a foreach loop in PHP, but I end up with lots of duplicates, and it looks very messy.
I also though about splitting it into multiple selects instead of using one, but I really would like to know if it can be done with one select.
Could someone help me with an MYSQL select? Thanks

When you do a JOIN that involves more than a 1:1 mapping between tables you're going to have duplicate data, and there's no way to get around that in the query.
You can break it out into multiple selects, or you can loop through the result set and pare out whatever duplicate information you don't want.
