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 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.

| 3 | show 3 | 32.5 |
| 2 | show 2 | 22.5 |

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);

I have table from mysql like below:
id | name | grade | k1 | k2 | k3 | s1| s2 | s3| e1 | e1 | e3 |
1 | Aa | 5 | 1 | 0 | 5 | 3 | 2 | 1 | 0 | 6 | 1 |
2 | Bb | 1 | 1 | 3 | 5 | 3 | 5 | 3 | 4 | 6 | 1 |
3 | Cc | 2 | 1 | 4 | 2 | 2 | 2 | 4 | 0 | 6 | 1 |
4 | Dd | 4 | 1 | 3 | 5 | 3 | 3 | 1 | 0 | 6 | 1 |
5 | Ee | 3 | 1 | 5 | 2 | 1 | 0 | 5 | 0 | 6 | 1 |
6 | Ff | 2 | 1 | 3 | 1 | 3 | 4 | 2 | 0 | 6 | 1 |
7 | Gg | 5 | 1 | 1 | 5 | 5 | 2 | 1 | 0 | 6 | 1 |
Using FOR and FOREACH looping, i do able to show all row. But in final view/table i want to
SUM [k1,k2,k3], SUM[s1,s2,s3] and SUM[e1,e2,e3]
So it will place new colum as K, S and E in each row.
Here are my code:
for ($i = 0; $i < Evaluation::model()->count(); $i++) {
foreach (Yii::app()->db->createCommand()
->from('evaluation')
->queryAll() as $item) {
// Row-Column start here
// id | name | grade | K | S | E |
}
}
thanks.
I love the query builder. So here is one of the solution.
$result = Yii::app()->db->createCommand()->
select('id, name, grade, (k1+k2+k3) AS K, (s1+s2+s3) AS S, (e1+e2+e3) AS E')->
from(MyModel::model()->tableName())->
queryAll();
var_dump($result);
select k1+k2+k3, s1+s2+s3, e1+e2+e3 from t
and it is not yii question, it is about MySql
If you want to express it in Yii, you can
Yii:app()->createCommands()
->select('k1+k2+k3, s1+s2+s3, e1+e2+e3')
->from('t')
->queryAll();
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.

ps_id is primary key
i am tying to make dynamic select list in php
i want a mysql query that can give service id which do not match with particular pack_id
like i have service_id 1,2,3,4,5
when i should select pack_id=1 then 3,4,5 should be displayed
and when i should select pack_id=2 then nothing should be displayed as it has all the 5 services.
thanks..
There are a few ways to handle this. The easiest is with a NOT IN subquery:
SELECT DISTINCT service_id
FROM
tbl_pack_service
WHERE service_id NOT IN (SELECT service_id FROM tbl_pack_service WHERE pack_id = 1)
